Porsche unveils a pair of incredibly expensive electric bikes

Porsche unveils a pair of incredibly expensive electric bikes


Porsche is another automaker that has tried its hand at making and selling electric bicycles. The result is both very interesting and very expensive. The Volkswagen-owned company has announced that it will begin selling a pair of advanced electric bikes this spring.

Porsche’s e-bike models are named Sport and Cross. The first is a road bike designed for everyday use, with full suspension, a carbon fiber frame, integrated front and rear lights, a Shimano engine, and a price that might surprise many. Sport, which weighs a little less than 22 kg, will cost about $ 10,700 – more expensive than most standard LADA cars.

Bicycles with carbon fiber frames are traditionally expensive, though, and the Porsche badge on the head tube also explains the price. In addition, racing bike enthusiasts spend a lot of money not only on the bike itself, but also on the expensive equipment associated with it.

In turn, the Cross, according to Porsche, is more suitable for off-road races. It also features Shimano drive, carbon fiber frame and full suspension, and oversized Magura-MT Trail hydraulic disc brakes that are “heat resistant”. It weighs exactly 22kg and will sell for $ 8,549.

The Shimano EP8 motor, which is used in both bikes, is described by Porsche as ultra-compact – it delivers up to 25 km / h speed in addition to the pedals. This may not seem high enough to many, but we are talking about the maximum legal speed allowed by the rules of the European Union.

Porsche bikes will surely find an audience with people who love the 911 or the Taycan, but it remains to be seen if this will translate into a long-term business for the automaker or remain a one-off experiment. Both bikes will be available for purchase starting in the spring of 2021.

Тарелка SpaceX в процессе разборки (Ken Keither)


SpaceX says it is building a facility in Austin, Texas to build systems that will help mass and efficiently manufacture phased array dish antennas, Wi-Fi routers and other equipment for Starlink satellite broadband customers. The news was made public by an automation and control engineer vacancy pointed to by the local news channel KXAN.

“To meet global demand, SpaceX opens new, state-of-the-art manufacturing facility in Austin, Texas, – says the message about the vacancy. – The automation and control engineer will play a key role as we strive to produce millions of consumer devices that we will start shipping directly to customers (plates Starlink, Wi routers-Fi, mounting equipment and so on) “

The plant presumably will not manufacture the plates and routers themselves on site, but instead design systems that will improve the manufacturing process. “Specifically, specialists will design and develop control systems and software for equipment of production lines – ultimately solving the most complex mechanical, software and electrical problems that arise in large-scale production, while maintaining an emphasis on flexibility, reliability, maintainability and simplicity. use “, – the message says.

Starlink is in beta testing and currently serves more than 10,000 customers, and the company has asked the FCC for permission to deploy up to 5 million user terminals across the country. SpaceX calls this piece of equipment “Dishy McFlatface” and it receives transmissions from SpaceX satellites in low Earth orbit. Starlink charges $ 99 per month plus a one-time $ 499 fee for a custom terminal, mounting stand, and router. Starlink recently began accepting pre-orders for a service that will be available in the second half of 2021.

The new vacancy said the successful candidate would work in Austin, but spend up to 25% of the time at SpaceX’s Los Angeles headquarters until the Austin facility is fully built. The new engineer will have an impact on Starlink’s ability to supply equipment this year. “The specialist will set, implement and adhere to schedules and budgets to ensure the completion of the project, as the company aims to roll out services in more than 25 countries by the end of the year,” – says the job posting.

The vacancy also states: “The engineer will design, develop and lead automation and control projects for consumer electronics manufacturing that are easy to use for people around the world, but technically very challenging – this includes an initial factory idea, online commissioning and validation of technical feasibility. in practice, with the subsequent transfer of the project to operational teams. He will also lead the project and the initial conceptual design of the equipment, carefully balancing product specifications, process requirements, layout complexity, cost and lead times. ”

SpaceX’s new plant will be located next to Tesla’s planned car plant. SpaceX founder and CEO Elon Musk is also Tesla’s CEO.

By the end of the decade, Europe plans to produce up to 20% of the world’s leading chips

Источник изображения: TSMC


Since last year, European countries have been trying to work out a general program for the development of the semiconductor industry, which would make it possible to organize the production of 2nm products in the region. The updated plans imply an increase in the share of European products to 20% in the segment of advanced lithography by 2030 in value terms.

The development of a new policy document was announced this week by Bloomberg. It is planned to consider it by the European Commission next week, but the main provisions of the program may still be changed. The local authorities considered the organization of the production of advanced semiconductor components in Europe earlier, now the scope of this production is being set – in value terms, they should amount to at least 20% of the world by 2030, if we talk about advanced lithographic technologies with norms below 5 nm.

The establishment of technological sovereignty will be achieved by reducing the degree of Europe’s dependence on other regions in critical areas, as stated in the preliminary version of the document. It received the provisional name “digital compass”, and describes the program for the development of the region in several directions. By the end of the decade, Europe plans to have at least 10,000 carbon footprint data centers operational, and to provide fifth-generation connectivity to all populated areas. By 2025, Europe expects to launch its quantum supercomputer. The number of young companies with a capitalization of more than $ 1 billion is planned to double by the end of the decade. Additional funds will be allocated for their development.

The development program provides for monitoring the intermediate stages of implementation, a detailed forecast of progress will be published annually. To adopt the program, it must be approved not only by all members of the European Union, but also by the regional parliament. Back in October last year, there were calls to develop such a plan by March this year, so so far the initiative is being implemented in accordance with the planned schedule.

ISS service life was extended until 2028, RSC Energia said

ISS service life was extended until 2028, RSC Energia said


According to network sources, the operation of the International Space Station in Earth orbit will be extended until 2028. RBC writes about this with reference to the words of the Deputy Head of the Center for Flight Operation of Spacecraft and Launch Vehicles of RSC Energia Yuri Gidzenko.

We are already thinking, and a decision on this at the upper levels has already been made, so that the station will fly until 2028“, – said Mr. Gidzenko, adding that the recently discovered microcracks in the ISS skin after sealing will not affect the service life of the orbital station.

It was also said that the cosmonauts are currently working to eliminate a crack 22 mm long and 0.1 mm wide in the Russian Zvezda module. Work to eliminate the second crack should begin on March 8-9, and it is planned to complete them by March 12. Official representatives of the state corporation “Roscosmos” refrained from commenting on this issue.

For the first time, a small air leak on the ISS was recorded in the fall of 2019. Since then, the station crew has been able to locate the leak in the intermediate chamber of the Russian Zvezda module. Several times they tried to seal the crack with the help of improvised means, but this did not bring any result. In February, the ISS was delivered the equipment necessary to search for and eliminate microcracks.

TSMC auctioned off surplus capacity despite huge orders

TSMC auctioned off surplus capacity despite huge orders


Currently, manufacturers of semiconductor products are actively working on fulfilling the accumulated orders in order to somehow solve the global problem of the shortage of microcircuits. Despite this, the Taiwanese TSMC, according to a network source, auctioned off its “excess capacity” for the production of silicon wafers.

According to the available data, the buyer was determined in the framework of the auction. However, the source does not specify what TSMC production facilities are in question, as well as who won the auction, but it is assumed that the winner was a representative of the automotive industry. It is worth noting that automakers suffer more than others from a shortage of semiconductor products. Many of them have already had to cut back on vehicle production or have voiced such a possibility, citing a shortage of car chips.

The coronavirus pandemic, complex manufacturing processes, logistical problems, the U.S.-China trade war have all led to an unprecedented shortage of semiconductor products around the world, despite silicon wafer makers increasing production by 40% last December.

The bad news is that most likely it will not be possible to cope with the shortage of microcircuits in the near future. According to many analysts, the current situation will continue until next year, when supply should catch up with demand and the situation will stabilize.

The model in question is the most modest in the ConceptD series both in screen diagonal (23.8 inches) and in resolution (Full HD). At the same time, the price is expected to be the lowest in the series: overseas CP1241YV is offered without discounts in the Acer online store for $ 230 (with a discount that was in effect at the time of preparing the material, the cost was even more attractive – $ 200).

With a price tag that is quite humane for a fast IPS model with a functional stand, the traditional advantages of the ConceptD series are promised: factory calibration with a DeltaE deviation level of <2 and wide possibilities for working with color. In theory, everything looks great, but it's time to test it with practice.

The declared characteristics of the monitor clearly show the gaming origin of the model, and it is also easy to establish the possible “progenitors”. They seem to be representatives of the budget-gaming line of Acer Nitro, namely the VG240YS or VG242YP models, which coincide with our test subject in all the main parameters, except for the presence of factory calibration and the functionality of the stand. And the monitor of the same series Acer Nitro XV240YP differs only in color.

The monitor uses the TPM238WF1-LF1F-Q matrix, which we learned about from the device’s service menu. This matrix is ​​also used, for example, in ASUS TUF Gaming VG249Q and VP249QGR gaming monitors (but without overclocking to 165 Hz).

⇡ #Packaging, delivery set, appearance

The monitor comes in a box made of unpainted cardboard with a rather laconic, but quite informative design. The “facades” and the ends of the box look absolutely identical. In the first, there is a stylized image of the monitor, information about the series, model, diagonal and resolution. Some more detailed information (matrix type, response time up to 0.1 ms, refresh rate up to 165 Hz, 95% DCI-P3 coverage, Adaptive Sync and HDR10 support) is given at the ends of the box.

On the upper edge, the main technical characteristics are once again duplicated and the unpacking diagram is applied.

The dimensions of the package are quite modest and the weight is small. On the sides there are small cutouts for a more comfortable grip – it is quite handy to carry the box.

From the sticker on the side of the box, you can find out a number of technical characteristics of the model, batch and copy number, as well as the date and place of release (December 2020, China).

The delivery set includes:

  • power cable with Schuko plug;
  • HDMI cable;
  • DisplayPort cable
  • multilingual user manual;
  • Warranty brochure
  • a leaflet with the addresses of the company’s offices in the EMEA region;
  • a sticker with information about the power consumption of the model;
  • Factory Calibration Report Sheet.

The display has narrow bezels on three sides, but is quite thick.

On the sides in the lower part of the case there are built-in two-watt stereo speakers.

On the right there is a small signal LED that lights up in orange during operation. You cannot turn it off, but due to its small size and low brightness, it does not distract when working.

There is a protrusion on the back of the display, at the top of which there are ventilation holes. The glossy manufacturer’s logo in the corner is initially protected with a transparent film.

In the lower part of the case, on the back, there are connectors for connection and controls.

The set of connectors is not very rich, but it is quite sufficient: one DisplayPort 1.2 input, two HDMI 1.4 and a headphone output.

Management is traditional for monitors of this company based on a combination of a mini-joystick and three separate buttons. The power off button is located just above the control buttons. On the side of the screen opposite the controls, there are notches that make it easier to navigate by touch.

The technical information on the sticker under the connector panel does not add anything new to what we already learned from the sticker on the box.

Above there are two more small stickers: with the manufacturer’s contact information and with the model’s energy efficiency parameters.

The stand is traditionally assembled from two parts. The metal base of the structure is covered from above with plastic pasted over with a wood-like film.

There are four large anti-slip stickers on the base of the stand. To connect the stand pieces, it may be necessary to rotate the base plate until the hole in it aligns with the anchor point of the center column.

No screwdriver is required for assembly: the fixing screw is equipped with a hinge.

If the central column is made of metal, then the hook for fixing the wires near it (the only hint of cable management provided in the monitor design), which also looks metal, is actually made of plastic.

Adjustment is available in the angle of inclination of the screen (in the range from -5 to 25 °), in height (in the range of 120 mm), and rotation is possible through 360 °.

It is also available to rotate the screen to portrait mode in both directions (this allows you to dock two monitors when working together with narrow upper frames).

Despite the abundance of adjustments, the centering is done very well: there is practically no need to adjust the angle from the position in which the screen is fixed when the force drops during the turn.

The build quality is generally satisfactory. You can only find fault with some unevenness of the screen adherence to the lower and upper frames. Other gaps are uniform and minimal, the color quality of the elements is good.

With normal adjustments, the monitor does not emit any sounds; when you try to twist the screen, you can hear a slight crunching sound.

⇡ #Menu and control

In general, the organization and design of the menu is well known to us from other models in the series.

The first press on any of the control buttons brings up a small menu at the right edge of the screen.

Pressing the mini-joystick leads to a transition to the main menu, and to the control buttons – a transition to the action assigned to them (changing the image mode, brightness or selecting an active input).

When entering the main menu, the value of the actions of the additional keys changes: the upper one is responsible for calling up an information window with data on the current operating mode, the lower one closes the main menu, and the middle one serves for quick selection of the image mode.

The information window displays information about the signal source, resolution, horizontal and vertical frequency, current image mode and serial number of the monitor. Also, it is from this window that you can reset to factory settings.

In total, the menu includes six main sections, the first of which is devoted to adjusting the basic elements of the image. Here you can adjust brightness, contrast, black gain, blue filter, enable dynamic contrast, HDR mode and high sharpness mode (we recommend turning off the latter even in those modes where it is active by default, since it does not affect the display of fonts in the best way).

In the second section of the menu, you can adjust the color settings. On the first page of the section, there is a choice of gamma and color temperature (both from the preset modes, and through amplification and RGB mixing in the user mode).

On the second page of the section, there is a choice of image mode and color space (options are available sRGB, Adobe RGB, Rec. 709, EBU, DCI-P3, P3-D65, SMPTE-C, HDR and standard mode with full matrix gamut). You can switch to grayscale mode and adjust the Hue and Saturation in six components.

The set of tools for fine-tuning the color is more than solid, but you can take advantage of these possibilities only with a standard color gamut. In modes with a choice of limiting the color gamut, it is possible to change only the brightness (which, however, is already better than that of some competitors).

The third section is devoted to sound settings. You can adjust the volume or mute the sound altogether.

The fourth section is devoted to game settings. Here you can adjust the responsiveness, enable adaptive frame sync, enable display of refresh rate in the corner of the screen, VRB with black frame insertion (available at refresh rates 144 and 165 Hz) and ultra-low latency.

The next section concerns the menu settings: language, display time on the screen, transparency and blocking.

The default language is English (for a change, we used it this time), but, as in the case of the models already familiar to us, the Russian localization is done quite well.

The last of the main sections of the menu is responsible for system settings. Active input selection, auto input selection, aspect ratio selection, button reassignment, DDC / CI control, HDMI black level, monitor quick start (no splash screen).

The buttons can be programmed to perform actions such as selecting a mode, adjusting brightness, contrast, volume, turning on the blue light filter or overclocking.

Also in the main menu there is a sub-item that allows you to save the current settings to one of the preset picture profiles.

We were able to access the service menu of the monitor. With its help, you can find out the model of the monitor and matrix, the firmware version, adjust the RGB gain for various presets, find out the backlight operating time and the status of Adaptive Sync (which is directly called FreeSync here), as well as make some other changes.

⇡ #Testing technique

The ConceptD CP1241YV monitor was tested using the X-Rite i1 Display Pro colorimeter and Argyll CMS software with DisplayCAL and HCFR Colormeter. All operations were carried out in Windows 10. During testing, the monitor was connected via the DisplayPort 1.2 interface to a GeForce GTX 1070 video card with the current driver at the time of testing. The refresh rate of the screen during testing was the maximum available 165 Hz.

In accordance with the methodology, we will measure the following parameters of the monitor:

  • brightness of white, brightness of black, contrast ratio at backlight power from 0 to 100% in 10% steps;
  • color gamut;
  • color temperature;
  • gamma curves of three primary RGB colors;
  • gray gamma curve;
  • color deviation DeltaE (according to the CIEDE1994 standard);
  • uniformity of illumination with brightness in the central point of 100 cd / m22

All measurements described above were performed before and after calibration. During our tests, we measure the main monitor profiles: default, sRGB and Adobe RGB (if available). Calibration is carried out in the default profile, with the exception of special cases, which will be discussed further. For monitors with wide color gamut, we select sRGB hardware emulation if available. Before starting all tests, the monitor warms up for 3-4 hours, and all its settings are reset to factory settings.

We will also continue the practice of publishing calibration profiles for the monitors we tested – the link can be found at the end of the article. At the same time, the 3DNews test laboratory warns that such a profile cannot 100% correct the shortcomings of your particular monitor. The fact is that all monitors (even within the same model) will necessarily differ from each other by small color errors. It is physically impossible to make two identical matrices, so a colorimeter or spectrophotometer is required for any serious monitor calibration. But a profile created for a specific instance can improve the situation for other devices of the same model, especially in the case of cheap displays with pronounced color rendering defects.

⇡ #Working parameters

By default, the settings for the main parameters are as follows:

  • image mode – Standard;
  • brightness – 80;
  • contrast – 50;
  • gain black – 5;
  • gamma 2.2
  • RGB gain – 50/50/50;
  • mixing RGB – 50/50/50;
  • response time – Normal;
  • high sharpness – off

During manual tuning (100 cd / m22 and 6500 K), the parameters took the following form:

  • image mode – User;
  • brightness – 0;
  • contrast – 50;
  • gain black – 5;
  • gamma 2.4;
  • RGB gain – 38/43/39;
  • mixing RGB – 50/50/50;
  • response time – Normal;
  • high sharpness – off

The edits affected not only the usual changes in brightness and RGB gain, but also the gamma setting: with preset 2.2, the actual gamma level does not even reach 2! The choice of 2.4 turned out to be optimal, although even with this setting, the result is slightly below the standard level of 2.2.

⇡ #White Brightness, Black Brightness, Contrast Ratio

The initial check was carried out in the default “Standard” mode with the factory settings of the main parameters with the HDR mode disabled in the Windows 10 display settings and the brightness was set from 0 to 100 in increments of 10.

Brightness in the menu White Brightness (cd / m22) Black luminance (cd / m22) Static contrast (x: 1)
one hundred 291 0.2092 1391
90 268.2 0.1929 1390
80 245.1 0.1764 1389
70 221.4 0.1593 1390
60 205.1 0.1477 1388
fifty 188.6 0.1359 1388
40 172 0.1239 1388
thirty 163.5 0.1178 1388
20 146.2 0.1055 1387
ten 128.6 0.0927 1387
0 110.7 0.0797 1389

Maximum screen brightness declared at 250 cd / m22, turned out to be significantly higher – it stepped over the mark of 290 cd / m22… However, the minimum luminance level of the screen turned out to be unpleasantly high – more than 110 cd / m22, which will not suit every user (especially if he prefers to work in the dark). The target level for our testing conditions is 100 cd / m22 managed to achieve only at zero brightness with reduced RGB Gain on all channels.

But the contrast in the entire brightness measurement range turned out to be significantly higher than the level declared by the manufacturer, amounting to approximately 1390: 1, which is an excellent result for IPS matrices.

VRB mode with black frame insertion can be activated by selecting a refresh rate of 144 or 165 Hz – when a frequency of 75 Hz is selected, the VRB option in the menu is disabled. Luminosity of the white field in VRB Normal mode is 224 cd / m22, and in VRB Extreme mode – 114 cd / m22, the contrast does not change compared to the standard mode. The brightness level in VRB-modes is locked: an attempt to change this parameter (as well as a number of others) leads to the transition to the standard mode.

On the whole, the implementation of the mode with black frame insertion is quite successful. VRB Normal mode will be appreciated lovers of bright pictures, and it is perfectly suitable for playing even in well-lit rooms. And VRB Extreme can be recommended those who do not like high brightness, andfor playing in a dark room.

⇡ #Measurement results

During testing, we focused on measurements in the standard mode with the full color gamut of the monitor, as well as with emulation of the sRGB color space.

⇡ #Standard mode, default settings

Let’s start with the results shown at the factory default settings of the monitor in the “Standard” mode.

The full color gamut of the matrix is ​​132.9% sRGB, 91.2% Adobe RGB and 93.7% DCI-P3. The coverage of these spaces, of course, is more modest: 99.7% sRGB, 81.7% Adobe RGB and 91.6% DCI-P3 (which is slightly less than the promised 95%).

The color temperature is fine-tuned: except for very low gray levels, the deviation from the target value does not exceed 100 K.

The grayscale is grouped quite tightly, but the white point is far from the target position.

The gamma curves run well above the reference level (average gamma value is 1.94), although the discrepancy between the individual colors is minimal.

The Argyll test with standard settings did not pass in any of the parameters, which is quite easily explained by a significant deviation of the white point from the target position, a greatly underestimated gamut and an extended color gamut.

⇡ #“Standard” mode after setting

Changes in RGB gain parameters have practically no effect on the color gamut of the matrix.

The color temperature has increased slightly, but remains fairly close to the target value of 6500 K.

The white point is noticeably closer to the target location, but the grayscale has lost some of its density.

The average gamma level was 2.17: the curves pass slightly above the reference level in the middle and right parts of the graph, and slightly below it on the left. A low level of discrepancy between the curves of individual colors was preserved.

Ручная настройка усиления RGB и изменение гаммы позволили значительно улучшить ситуацию с точкой белого. Примерно в полтора раза уменьшился и уровень отклонений на цветовых патчах, хотя и остался выше требований теста (максимальный уровень отклонений лишь чуть превышает запросы Argyll, но средний существенно выходит за допуски теста).

Впрочем, и это тоже предсказуемо: с учетом расширенного цветового охвата помочь уменьшить цветовые отклонения может либо ограничение цветового охвата на уровне sRGB, либо калибровка — и именно эти шаги мы последовательно и предпримем.

⇡ #Режим sRGB

В режиме sRGB единственной доступной настройкой является яркость, но даже при уменьшении ее до минимума она превышает 110 кд/м2

В режиме эмуляции цветового пространства sRGB цветовой охват матрицы оказался ограничен возле всех вершин цветового треугольника, причем эта работа в области зеленой вершины цветового треугольника была проведена не слишком аккуратно — «отрезано» оказалось явно больше необходимого. В итоге покрытие пространства sRGB составило 92,1% при общем охвате 92,4%.

Цветовая температура выше, чем в стандартном режиме, и примерно соответствует тому, что получилось у нас после ручной настройки.

Расположение точки белого и группировка оттенков серого близки к стандартному режиму, что уже навевает некоторый пессимизм.

Гамма-кривая светимости в режиме sRGB пролегает практически на том же уровне, что и в стандартном режиме (среднее значение 1,93), но расхождение между кривыми отдельных цветов свелось к минимуму — они почти совпадают друг с другом.

Результат заводской настройки режима sRGB, увы, разочаровывает — даже с допусками на погрешность измерений он не укладывается в обещания производителя. Очень сильно заниженная гамма и очевидно неточная установка точки белого, зафиксированные нами при измерениях, вряд ли оставляют шанс на точную настройку.

Цветовой баланс в режиме sRGB

Цветовой баланс в режиме sRGB

Стоит также отметить явную потребность в подстройке RGB Gain: при достаточно точно подобранной «средней по больнице» цветовой температуре наблюдается явный дисбаланс между оттенками: «недобор» по зеленому и «перебор» с синим.

На всякий случай мы провели измерения во всех трех вариантах, которыми можно получить цветовой охват sRGB через меню монитора (выбор цветового охвата в стандартном режиме, выбор режима sRGB и загрузка калибровочного пресета №2, который по умолчанию соответствует пространству sRGB), но результаты измерений во всех этих режимах различались на уровне погрешности — в пределах нескольких сотых DeltaE.

⇡ #Режим sRGB, результаты после калибровки

Поскольку в предустановленном режиме sRGB настройки усиления RGB Gain и гаммы недоступны, единственным способом улучшить результаты остается калибровка. Проведем мы ее в режиме ограничения цветового пространства sRGB, используя в качестве базы заводской пресет монитора для этого цветового пространства.

Цветовой охват после калибровки самую малость — на десятые доли процента — расширился.

График цветовой температуры после калибровки приобрел несколько изломанную форму по сравнению со стандартными установками или ручной настройкой, но при уровне серого более 25% отклоняется от целевого значения 6500 К весьма незначительно.

Расположение точки белого максимально приблизилось к требуемому, плотность группировки оттенков серого при этом не пострадала.

Гамма-кривые после калибровки пролегают вплотную к эталонной кривой (средний уровень — ровно 2,2), расхождение между кривыми отдельных цветов минимально.

Итоги теста Argyll после калибровки вполне ожидаемы: все тесты пройдены с хорошим запасом от рекомендованных показателей. Отклонение точки белого от идеала — 0,27 DeltaE, средний уровень цветовых отклонений — 0,25 единицы, а максимальный — ровно единица. Но подобный результат не редкость и для моделей, не претендующих на качественную настройку «из коробки».

⇡ #Прочие режимы

В целом остальные режимы, в которых может работать ConceptD CP1241YV, нам уже известны по другим моделям этой серии, поэтому подробно останавливаться на них вряд ли имеет смысл — тем более что в них все так же проявляются уже отмеченные нами недостатки заводской настройки в виде заниженного уровня гаммы и существенной ошибки в точке белого.

Цветовой охват в режиме Adobe RGB

Цветовой охват в режиме Adobe RGB

Предустановку Adobe RGB, несмотря на ее наличие, мы также на этот раз решили обойти стороной: охвата чуть больше 80% этого пространства (вдобавок «подрезанного» ограничением возле зеленой и красной вершин треугольника цветового охвата) явно недостаточно для полноценной работы с цветом.

⇡ #Равномерность подсветки

Равномерность подсветки дисплея проверялась после снижения яркости в центральной точке монитора до уровня 100 кд/м2 и установки цветовой температуры ~6500 кельвин.

Примерно так выглядит в темноте белый фон, выведенный на экран.

Картинка выше демонстрирует фотографию белого поля при определённой экспопоправке в ходе съёмки (в темноте) и дальнейшей программной обработке для более наглядного представления равномерности подсветки.

Наиболее заметны небольшие проблемы в углах (что вполне привычно), других явно выраженных недостатковне наблюдается (что приятно).

При измерении яркости по 45 точкам среднее отклонение от центральной точки составило всего лишь 4,03%, а максимальное — 13,79% (причем «в плюс» от центральной точки — в верхней правой части экрана!). Максимальное снижение светимости зафиксировано посередине левого края экрана и составило 12,88%. Этот результат можно назвать великолепным для IPS-матриц даже по меркам подобной скромной диагонали.

Отклонение цветовой температуры в единицах DeltaE в среднем составляет 2,08, а максимальное в правой части нижнего края экрана не превышает 3,4, что также можно назвать отличным показателем.

Отметим почти уникальный (по крайней мере, для моделей без компенсации неравномерности подсветки) факт: ни один из 45 квадратов не обведен красным цветом, свидетельствующим о превышении допустимых значений отклонений яркости или оттенка.

А при повышении яркости белого поля до 170 кд/м2 значительно уменьшается и число «желтых» зон.

При взгляде на черный экран в темноте невооруженным глазом заметна лишь небольшая засветка в левом нижнем углу.

После дополнительной экспоправки и обработки снимка становятся заметны небольшие засветки и по другим углам. В целом же с черным фоном дела обстоят вполне хорошо: традиционные угловые засветки почти незаметны, а других проблем на тестируемом экземпляре не отмечено.

⇡ #Качество градиентов и скорость отклика

Качество отображения градиентов до калибровки не вызывает нареканий. После калибровки границы между некоторыми группами оттенков становятся чуть более заметными, но общее ухудшение качества весьма незначительное — что можно назвать немалым достижением для матрицы 6 бит + FRC.

Скорость отклика в обычном режиме

Скорость отклика в обычном режиме

Модель ConceptD CP1241YV имеет три предустановки скорости отклика, из которых по умолчанию выбрана средняя, «Normal» (она же единственная работоспособна при активации функции Adaptive Sync). Этот выбор можно назвать оптимальным (по крайней мере, для высокой частоты обновления): шлейфы за объектами чуть короче, чем в режиме Off, но при этом не проявляют себя артефакты, явно заметные в режиме Extreme.

Скорость матрицы весьма хороша, но все же мы видели и более быстрые IPS-матрицы (например, на Acer Nitro VG272UV).

Скорость отклика в режиме VRB

Скорость отклика в режиме VRB

В «стробоскопическом» режиме VRB со вставкой черного кадра длина шлейфов меняется незначительно. Артефакты, как и в обычном режиме, заметны лишь при установке времени отклика Extreme.

При максимально доступной для монитора частоте обновления 165 Гц пропуска кадров не наблюдается.

⇡ #Углы обзора и Glow-эффект

При незначительных изменениях угла просмотра в горизонтальной плоскости картинка на экране совсем не меняется. Если увеличить угол до 30-45 градусов, то изображение становится чуть менее контрастным, немного снижается насыщенность некоторых цветов, слегка высветляются тени, появляются незначительные паразитные оттенки в той или иной части экрана — ничего необычного. При изменениях в вертикальной плоскости картинка на экране портится быстрее.

Glow-эффект у рассматриваемой модели выражен во вполне типичной для IPS-матриц мере. При обычном расположении пользователя перед монитором даже на темном фоне он практически не беспокоит, а при взгляде под более острым углом хоть и становится явно заметным, но раздражающие паразитные оттенки не бросаются в глаза.

⇡ #Кристаллический эффект, Cross-hatching, ШИМ

В мониторе ConceptD CP1241YV используется матрица с полуматовой защитной поверхностью, практически не вызывающей проявлений кристаллического эффекта, но достаточно эффективно борющейся с бликами.

Эффекту Cross-Hatching монитор также не подвержен.

Проработка мелких деталей и шрифтов достаточно хорошая и не требует дополнительных настроек (кроме отключения функции «Высокая резкость» в режимах, в которых она включена по умолчанию).

По заявлениям производителя, дисплей обладает Flicker-Free-подсветкой, что и было подтверждено в ходе наших тестов. При любом уровне яркости ШИ-модуляция не используется либо её частота составляет несколько килогерц или даже десятки килогерц.

В режиме VRB со вставкой черного кадра частота работы подсветки совпадает с частотой смены кадров (поддерживается работа при частоте обновления более 75 Гц). Нагрузка на глаза в этом случае, безусловно, возрастает, но и движущиеся объекты на экране становятся чётче. Для непродолжительной игры подобный режим может быть интересен, но в случае долгой работы за монитором его точно следует избегать.

С файлового сервера 3DNews.ru можно скачать цветовой профиль для этого монитора, который мы получили после калибровки в режиме эмуляции sRGB с отсечением выходящих за пределы этого цветового пространства областей.

Выводы

Надо сказать, что если рассматривать ConceptD CP1241YV как игровой монитор, то он получился более чем удачным — какими, вероятно, являются и его непосредственные «родственники» из серии Nitro, с которыми мы пока еще не знакомились. В его активе быстрая матрица с высокой частотой обновления, достаточный запас яркости и прекрасная для IPS-матрицы контрастность. Даже никогда не значившийся в числе ярких достоинств мониторов этой компании режим VRB со вставкой черного кадра настроен весьма удачно: с высокой для подобного режима яркостью и возможностью использования при различной частоте обновления, включая максимальную. Словом, как игровой Full HD-монитор наш сегодняшний знакомец если и не идеален, то как минимум очень хорош.

Проблема же заключается в том, что мониторы серии ConceptD позиционируются как профессиональные инструменты с высоким качеством заводской настройки и низким уровнем цветовых отклонений — а здесь у CP1241YV кроме похвально высокого уровня равномерности подсветки и цветовой температуры (подобных результатов можно было бы ожидать от моделей с системой компенсации неравномерности подсветки) нет заметных преимуществ.

Полученные нами результаты показывают заниженный уровень гаммы, ошибки в определении точки белого и отклонения цветов даже в режиме sRGB, к которому относятся обещания производителя об уровне отклонений DeltaE<2. Кроме того, не слишком аккуратно выполнена и эмуляция этого цветового пространства: от практически полного покрытия осталось лишь чуть больше 92%.

Возможно, проблема кроется в нашем экземпляре монитора (ведь все опробованные нами ранее модели серии ConceptD всегда в целом соответствовали обещаниям производителя по уровню цветовых отклонений, даже если к прочим параметрам настройки и имелись определенные претензии). Но для прошедшего через наши тесты экземпляра мы можем сделать вывод, что в качестве решения для работы с цветом он способен показать достойные результаты только после аппаратной калибровки.

Advantages:

  • хорошее качество материалов и сборки;
  • функциональная подставка с полным набором регулировок;
  • наличие VESA-крепления;
  • расширенный цветовой охват и возможности, который он дарит;
  • большое количество предустановок с эмуляцией различных цветовых пространств (в т. ч. и sRGB);
  • богатые возможности по настройке цвета (но лишь при расширенном цветовом охвате по умолчанию);
  • уровень яркости и контрастности ощутимо выше заявленного производителем;
  • хорошие градиенты без калибровки и лишь незначительное падение их качества после калибровки;
  • очень хорошая равномерность подсветки;
  • быстрый отклик матрицы при частоте обновления до 165 Гц;
  • наличие достаточно удачно настроенного режима VRB со вставкой черного кадра;
  • приятно оформленное и логичное меню с качественным переводом;
  • поддержка технологий адаптивной кадровой синхронизации, совместимой с видеокартами разработки как AMD, так и NVIDIA;
  • отсутствие Cross-hatching и различимого кристаллического эффекта при обычных условиях просмотра.

Недостатки:

  • откровенно слабый (особенно для метящей в профессиональный сегмент модели) уровень заводской настройки.

Может не устроить:

  • высокая минимальная яркость;
  • отсутствие USB-хаба;
  • возможность задействовать функции работы с цветом только при стандартном (полном) цветовом охвате матрицы.

Qualcomm launches Snapdragon Sound, a program to enhance audio quality in wireless headphones

theverge.com


Qualcomm today announced Snapdragon Sound technology, which the company itself describes as a collection of software and hardware innovations in the field of sound. Its goal is to deliver audio quality on wireless models comparable to high-end wired headphones.

theverge.com

Snapdragon Sound will take advantage of the latest Qualcomm processors, the company’s Bluetooth chips and audio codecs such as aptX Adaptive for Hi-Fi audio playback up to 24-bit 96 kHz. It’s worth noting that the concept of high-quality wireless audio is not new to Android device manufacturers. Sony has made a significant contribution here with the introduction of LDAC technology, which can transfer three times more data than the standard SBC Bluetooth codec is capable of.

Qualcomm components are used in headphones from many well-known companies, including Bose, Jabra, 1More, Sennheiser, Audio-Technika and Anker. However, the company said that existing devices will not receive support for the new technology. The Snapdragon Sound badge will appear on the packaging of upcoming smartphones and audio devices in the next few months. It is known that the first two partners of Qualcomm under the Snapdragon Sound program will be Xiaomi and Audio-Technica.

theverge.com

Qualcomm says the Snapdragon Sound certification will mean more than just that the device is capable of reproducing high quality audio. It is reported that the focus will also be on improving audio quality during voice calls and reducing latency during games to 89 milliseconds. In addition, high stability of the connection is a priority.

It’s worth noting that today’s Snapdragon Sound launch announcement follows Spotify’s recent announcement that it will offer premium subscribers access to lossless streaming audio by the end of this year. Other popular services like Amazon Music already offer similar options.

The Sims 4 fans accused EA of stealing over new paid bundles

The Sims 4 fans accused EA of stealing over new paid bundles


Recently, The Sims 4 has added $ 400 paid bundles that add exclusive content such as dust-fighting vacuums and special rewards associated with the activity. Not everyone liked the innovation. Some fans began to criticize Electronic Arts, accuse the publisher of theft, and urge it to ignore the sets.

A post from a user under the pseudonym Slaughter-Laughter appeared on the Reddit forum. In his message, a disgruntled player wrote: “I’m definitely not going to support EA anymore. I think they are a bunch of thieves. I don’t know if that matters, but I feel like the Sims community needs to act and share their opinions. One person won’t do anything. A hundred will do nothing, but if we increase this number to thousands or more? Don’t buy kits from EA. Maybe you should write EA and complain too. For me, the price of these kits is insane and clearly not what the community wanted. “

Next, Slaughter-Laughter accuses Electronic Arts of trying to cash in on The Sims 4 fans and not developing the game. He contacted EA support and received one set for free. Let us recall that by now the cost of the project with all the additions has already exceeded 50 thousand rubles.

A disgruntled fan post on Reddit garnered 2,000 positive comments. After him, similar publications from other users began to appear on the Web. As for Electronic Arts, it has not yet commented on the situation.

The Nord 2 will be the first OnePlus smartphone to be powered by MediaTek. Presentation – next quarter

The Nord 2 will be the first OnePlus smartphone to be powered by MediaTek. Presentation - next quarter


Last year, the mid-range smartphone OnePlus Nord debuted with support for 5G networks. As it has now become known, a second-generation device is being prepared for release, in which OnePlus will for the first time refuse to use the Qualcomm processor.

Let’s briefly recall the key characteristics of the current OnePlus Nord (in the pictures). This is a Qualcomm Snapdragon 765G chip, a 6.44-inch Full HD + Fluid AMOLED screen, 8 or 12 GB of RAM, a 128/256 GB flash drive. The front has a dual camera with sensors of 32 and 8 million pixels, and the rear quad camera has a configuration of 48 + 8 + 5 + 2 million pixels.

The Android Central resource told about the next generation device. It is claimed that the new product will enter the commercial market under the name OnePlus Nord 2, and the official presentation will take place next quarter.

For the first time in its practice, OnePlus will use a MediaTek processor instead of one of Qualcomm’s solutions. It will be the flagship 6-nanometer Dimensity 1200 chip. This product contains eight processing cores with a clock speed of up to 3.0 GHz, an accelerator Mali-G77 MC9 and a 5G modem (up to 4.7 Gbps).

Other characteristics of the novelty have not yet been disclosed. But it’s safe to say that the screen resolution will be at least Full HD +, and the main camera will absorb three or four components.

Samsung unveils ISOCELL 2.0 technology to improve camera quality in smartphones

Samsung unveils ISOCELL 2.0 technology to improve camera quality in smartphones


Samsung today officially unveiled ISOCELL 2.0 technology to improve light sensitivity and reduce noise in image sensors for advanced smartphone cameras.

The South Korean giant first introduced ISOCELL technology in 2013. It reduces color cross-talk between pixels by creating a physical barrier. As a result, small pixels are able to provide more accurate color reproduction.

In the first version of ISOCELL technology, physical barriers were fabricated using metal. This was followed by the ISOCELL Plus method: it assumes that the “walls” around the pixels are made on the basis of a new optimized material.

And now the ISOCELL 2.0 technology has been announced, which provides for further improvement of the structure of the barriers. As a result, light sensitivity is increased and color cross-talk is minimized.

As a result, even tiny pixels are able to absorb enough light to produce crisp, colorful, high-resolution images. Below you can watch a video with a story about ISOCELL technology:
