After she became the first manufacturer of computer displays, which submitted a production model – ASUS PQ321QE. By the way, this reminds breakthrough, in our opinion, the similarity of ASUS and Samsung: Taiwanese, as Koreans tend to be better in all areas at once. And have to admit it is perfectly possible.

    Our guest today – a special monitor in all senses. First, he has a giant diagonal – 31.5 inches. Second, it has an unprecedented panel of computer monitors resolution 3840×2160. Third, the matrix display is based on the latest technology IGZO, developed by Sharp. And fourthly, ASUS PQ321QE – so far the only monitor on the market with such characteristics. But first things first.

    Rising diagonal screens, as we mentioned, caused an increase in resolution panels. Array corresponding to the resolution of Full HD, for example, for monitors with 27-inch matrices have been enough, since each point can be seen on the screen with the naked eye at normal distance that separates the user from the display. Therefore, advanced models have screens with a resolution of 2560×1440 or 2560×1600. Apparently, ASUS has decided not to wait for the moment when such an array would be enough for an expanding diagonal monitors and equipped the new model panel with a 4K.

    There are as many as four versions of this format: full-frame (4096×3112), academic (3656×2664) widescreen (4096×1714) and kashetirovanny (3996×2160). However, resolution of the matrix of our guest today does not match any of the substandards. In fact, everything is simpler than it seems: 3840h2160 – this four-screen Full HD. Thus, in our view, familiar. Most likely, in the future, manufacturers of computer monitors will specifically target this permission. As for support from the video card manufacturers, for the image of today’s video cards to play with any aspect ratio is not particularly difficult.

    As we have already mentioned, the matrix is ​​based on ASUS PQ321QE technology IGZO. The name is an acronym and stands for Indium Gallium Zinc Oxide – indium, gallium, and zinc. ” This is also a semiconductor material, and is designed to replace the amorphous silicon in the active layer of liquid crystal screens. One of its key features is the ability to control the thin film transistor smaller. This, in turn, reduces the size of the picture element, to increase its speed and pixel density and reduce power consumption. Furthermore, the matrix may themselves be thinner analogs produced by other processes. All of these benefits are important primarily in mobile devices, which explains the interest in the technology from the company Apple. However, the firm Sharp demonstrated that can produce displays of almost any size.

    Among other things, it is worth mentioning the internal representation of the basic colors in the form of a ten-digit binary numbers. This allows to display a total of over one billion colors. Such a huge amount of color gradations needed primarily for smoother display different color gradients, such as the dawn sky or water surface of the lake. All these advantages suggest ASUS PQ321QE really innovative product. And we can not wait to try it in the case.

    By the way, our guest today, apparently, will not remain alone: ​​Dell has announced a summer display Dell UltraSharp 32, which has similar characteristics and will be available in the near future. A firm Sharp additionally equips its model Sharp PN-K322B touch layer. It should be noted that for those who screen size 31.5 inches seems appropriate enough for work, ASUS has shown at Computex 2013 another display with the same resolution, but with a diagonal of 39 inches.

    So, the display brightness is declared at 350 cd/m2. It does not record the value, but still one of the highest. 800:1 contrast ratio. Compared with most models on the market which claim 1000:1, our guest today looks a bit tatty. However, in our view, a value much closer to the truth – and it can not command respect. Dynamic contrast is absent – and correctly.

    Response time is as much as 8 ms. In these times when even a relatively slow IPS-panel pulled up to 5 ms, it is quite a lot. With regard to support video interfaces, everything is very simple: developers equipped model only connector DisplayPort – in this case, a necessary and sufficient. External power supply – it is not very convenient for wall placement of the monitor. In our opinion, in such considerable size model could try to mark the secondary voltage source inside. Display to hang on the wall, the developers provided a seat for a standard VESA mount size of 200×200. Indeed, this format is better suited for such a huge panel than normal 100×100. By the way, for the dismantling of support will have to use a screwdriver.

    Power consumption model, despite assurances from developers panel quite high – 93 watts. In our opinion, the reason for this in the first place is an impressive statement brightness, as well as a solid screen sizes. However, even this does not explain such high values, if you count the proportion relative to the area of ​​the screen with a diagonal of 27 inches with the same luminosity passport, it should turn out just 59 watts. Solid weight – 13 kg – gives the monitor additional stability on the work surface.


    Package models – to match the display, such as large, and its weight is as much as 17 pounds! These data should be borne in mind in the case of shopping as usual plastic handle on the top face of the box is not (she just can not cope with such a mass), and on the sides with only a couple of slots for fingers. If the monitor image is not on the package, you would think that is inside the TV.

    We have before us a monitor that has managed to get on the test, so checking with the instructions, which can be downloaded on the official website of the company, and find out how grade coincides with the list of accessories attached to the display.

    ASUS PQ321QE – package

    In addition to the monitor, the box contains the following accessories:

    • Cable DisplayPort to DisplayPort;
    • Cable USB to USB;
    • Cable RS-232C to mini jack;
    • Power supply;
    • Power cable;
    • Set of clamps for cable;
    • Set of screws;
    • Allen key;
    • Quick Start Guide;
    • Manual;
    • Warranty card.

    ASUS PQ321QE – supplied

    The list of accessories is identical to what we found inside. In addition, it is worth considering the undocumented cable USB to USB. It is worth noting, and it is traditional for the company ASUS, grade monitor that very rich. It has everything to begin work immediately, as well as several other pleasant things, such as plastic clips that will tidy display all cable connections.

    As usual, in order to use the space inside the package more effectively, the developers made a structure consisting of three parts: the base of support, the support itself and the liquid crystal panel. To connect these parts require a screwdriver and hex key, bundled. Next will only connect the power cable and interface cables, and then you can start to work.

    ASUS PQ321QE – Package: panel and prop assembly

    Design, assembly

    Even a brief introduction to the design of the model to evaluate how our guest today will be convenient in everyday use. Its design means that the user can adjust the position of the panel as it is comfortable, and quickly modify it according to the current task. And the appearance of the display will not distract the attention – I f it were not outstanding size, ASUS PQ321QE nothing would be no different from dozens of similar displays. Here, everything is designed for practicality and ease of use for a long time, not instant wow effect. Crisp geometric lines drawn with a ruler like. Matte texture go well with various shades of gray. The front panel is decorated with a company logo and discreet icon DisplayPort.

    To say that the device looks impressive on the desktop – then only voice obvious. The screen takes up almost the entire visible area user, leaving only a small part of it to another situation. And when the screen image is there, the user ASUS PQ321QE definitely feel what it means to be “absorbed by the spectacle.”

    Our guest today uses LED backlighting, however, despite the use of an external power supply, the panel can not be considered absolutely fine. In our opinion, the reason for this is the increased screen frame design and serious passive cooling for silent operation.

    Similar models, if we talk about flagships, usually equipped with all possible interfaces. However, in our case, the developers have installed a connector DisplayPort. And rightly so. The fact that the whole video stream can pass extensive lossless only this digital interface. For comparison, to ensure full operation of a similar model ASUS PQ321Q, requires just two HDMI-cable. Well, about analog protocols and no speech.

    It should be noted that in the model of this level would not prevent a complete USB-hub third version. But he’s not here. But our guest today is a complete multimedia device. It is very convenient because you can watch a movie or listen to music without having to worry about additional equipment. Moreover, for this purpose need only one cable. However, for demanding users always have the ability to connect external speakers. By the way, built sound sources do not give out your location even with careful examination.

    Of course, it should be noted multifunction support. This adjustment is available all possible degrees of freedom: the height, tilt the panel around the pivot axis of the support – and the rotating display from the horizontal to the vertical position. However, it is worth noting that the change in elevation occurs several tugovato: mechanism as if something is held in place – need to apply a force to move the panel. Moreover, despite the stated possibility portrait and landscape orientation, rotate the panel could not be implemented, as excessive force may damage the mechanism.

    Controlling the Monitor made using classical keys located on its right side wall. They are pressed gently and allow to configure the display. Unfortunately, during testing finger periodically hitting the off button on the screen, which, by reason of the video led to the need to reboot the computer. Well, as usual, no backlight controls manufacturer has not provided, and in fact, this solution could be very helpful for users who prefer to work in low ambient lighting. It should be noted that the controls can not only navigate through the menu, but also adjust the brightness and volume built-in speakers.


    Menu model clearly structured – to understand it will not be difficult. However, such a design that the impression that before us is not a serial pattern, and engineering.

    “Image” allows you to adjust the picture settings such as brightness, contrast, black level, hue and sharpness. Additionally, there are additional color adjustments, where you can select the image processing component of the gamma curve and one of the color temperature presets, and set it by adjusting the basic colors per channel. In addition, you can define the color range of the input signal, as well as to carry out a general reset all settings to the factory level.

    Submenu “Setup” is responsible for such functions of the monitor as interface language, the choice of inputs for audio and data transfer rate to the service port.

    Item “Monitor” allows you to select the orientation of the panel, and enable hibernation during prolonged.

    In the submenu “Other”, you can activate the suppression of residual images, choose the method of displaying input, mute, as well as to display all the information about the monitor.

    In addition to all of these settings are available in the main menu, there are additional hidden adjustment. A certain combination of buttons displays a special window with the title “Options”, which allows a complete reset of all parameters locked to other users the ability to configure the monitor and control the service port, define a mapping of the main menu to activate the LED and output hardware error messages and overheating monitor.

    It is worth noting excellent written instruction manual. Here is everything – from the assembly and laying methods monitor power and signal cables to describe settings and display control using a service COM-port. This instruction is useful to both novice and experienced users.

    As for the quality of localization menu, it is generally good, but some of the terms such as “mute AUDIO” raise a smile.

    How 4K works

    With connection 4K-screen business while things are not so simple. Firstly, ASUS PQ321QE, as his future colleagues, is a “tile” monitor. This means that it contains two controllers, each of which serves a matrix half. The computer takes it as two separate logical display that you want to connect in one piece with the help of such software solutions like AMD Eyefinity and NVIDIA Surround.

    Why is it so difficult? Just on the market is no controller for monitors, which could in real time to process such a crazy amount of data. For example, if the resolution 4096×2160, 24-bit color and a refresh rate of 60 Hz over a flow of 500 M / s. Hence the need for “tile” design until the relevant performance chips.

    Do not be embarrassed that ASUS PQ321QE to connect to the video card is content with a single cable DisplayPort. In this case the interface should operate in a MST (Multi-Stream Transport), to transmit data to multiple (in this case, logic) displays via a shared port. Among the specifications of discrete graphics cards DisplayPort 1.2, which include the MST, satisfy the model on GPU NVIDIA, since GeForce 600 architecture Kepler, and AMD – the Radeon HD 6000. Integrated Graphics Intel received support DisplayPort 1.2 processors Haswell, and APU from AMD again a little earlier – in the generation of Trinity. We must keep this in mind because when earlier versions DisplayPort maximum resolution the screen limited modest standard WQHD – 2560×1440.

    Moreover, unlike the model ASUS PQ321Q, in the case of ASUS PQ321QE impossible workaround – can not be connected to two separate video card HDMI cables into force complete absence of such ports. In practice, the combined assembly of the desktop displays two logical gone quite smoothly. Driver NVIDIA Surround mode automatically includes two monitors, correctly guessing the mutual arrangement of “tiles”. Software requires AMD Eyefinity enabled and configured independently, but afterwards it works equally well on both video cards manufacturers. Only claim to AMD: when reconnecting the cable signal is lost, it is necessary to restart the PC.

    ASUS monitor displays without problems everything that happens before loading Windows, with one caveat: if the graphics card from AMD, the display switches to intelligently SST (Single-Stream Transport), in which a low-resolution picture is centered. In conjunction with the NVIDIA monitor does not wish to leave the MST, and the result is displayed in the BIOS “tile”, which, however, does not matter from a practical standpoint. Well, now for the tests.

    As usual, all the picture presets are ready combination of brightness, contrast, hue, gamma curve index and color temperature. And within each preset, you can adjust all the options available, and these settings are retained even after switching to other modes. In addition, part of the indices can be changed regardless of the mode. Due to the availability of adjustments all the possible options and the lack of impact of any installation mode “Standard” at the moment becomes a major contender for the title of the user.

    Testing Methodology

    Testing conducted using a colorimeter Spyder4. For most measurements used Spyder4Elite software for Windows (version at the time of this testing – 4.5.4).

    At the moment, to measure following image options are available:

    • white field parameters for different values ​​of the brightness setting of the display;
    • brightness of black and white field;
    • contrast;
    • color gamut;
    • gamma curve shown in white;
    • the stability of the color temperature of the white area for different values ​​of brightness video;
    • ΔE – a measure of color accuracy;
    • uniformity of the backlight.
    1. In the first phase of testing, our goal is to study the possibilities of the monitor, which can get a user without special equipment. To do this, we will measure the basic modes of image parameters are set by default. We first examine the preset monitor compliance gamma curve reference graphics, explore color temperature constancy in the entire brightness range, and will test the maximum width of the display color gamut and fidelity of individual colors.
    2. Further, if possible, we subject mode, claiming the title of the user (and thus equipped with the maximum possible number of settings), additional tests. Typically, these measures include the study of stability and color temperature of the transfer function for compliance with the standard with different indices of the gamma curve, as well as studying the brightness and contrast with certain preset white point. Note that all measurements are made with the maximum brightness and contrast by default.
    3. After that, we have to analyze all the results and select the combination of settings for further research. Priority is given to modes with maximum brightness and contrast, however, attention is also fidelity of individual colors, the transfer curve, as well as the stability of the color temperature.
    4. Further, this setting is used to measure the brightness and contrast settings for different levels of display luminance, and then – to measure the uniformity of illumination on the field screen.
    5. When all the initial measurements were carried out and we have learned that the monitor can provide a standard user, it’s time to explore the boundaries of the display, that is, to find out what the maximum parameters of the device, which can be obtained using special equipment. For the implementation of this phase of testing, we will need to conduct the calibration process. As you know, after reduction to the standard parameters of the monitor some indicators are better (usually a separate fidelity of colors), and some (such as brightness and contrast), in contrast, subside. Therefore, we analyze the performance before and after calibration and make a conclusion about the effectiveness of this process.

    Note: The attentive reader will notice that the performance maximum brightness in the different dimensions are slightly different. Of course, nothing critical in this: range of values ​​- it is a natural phenomenon, because even if you hold two successive measurements of the same parameter keeping all other conditions, its value will usually differ slightly from each other. Knowing this property gauges, testers usually lead all the results together with an error, but in our case this is not possible: Spyder4Elite Calibrator provides only average.

    Test Results

    Engineers monitor equipped with only three specialized image processing modes: “Standard”, “Chroma” and sRGB. Agree, does not sound as smooth as we would like, but we give the names as they appear in the menu. These preset with default parameters and we shall study in the first place.

    By the end of the brightness range width measurements our guest today demonstrated just great results. The maximum level of the white point was as much as 413.9 cd/m2. Excellent! Our experience suggests that it is better – 416 cd/m2 – made ​​only professional model NEC PA241W. Aside from a peak of contrast equal to 3900:1, at the beginning of the range, the maximum value – 730:1 – achieved with 75% of the highest luminosity. It should be noted that this level is only slightly less than the stated value of 800:1. Furthermore, such a result can be called great, because it higher than any IPS-monitors visited we tested.

    On the analysis of the results of the measured brightness values ​​revealed that the best in this category was the measurement mode “Standard” His record of the white level was a record 416.9 cd/m2. Great! NEC PA241W Professional now only in second place. Following the preset “standard” – literally neck and neck – should be preset sRGB, the result of which was 416 cd/m2. Excellent record. By the way, normally with the same name can not boast of outstanding achievements in this category. And closes the three preset “Color.” His level of luminosity – 414.8 cd/m2, which is also safe to assume a remarkable result.

    In the category of the measured contrast modes were all the same, and equally great. Since all indicators brightness presets are very close, and black levels did not change during the measurement, the average ratio of the luminosity of the white and black all presets found to be 780:1. It should be noted that this is not only a great figure in absolute terms, especially in comparison with IPS-performance monitors, but also – for the first time in a long time – a result very close to the declared level.

    As for color temperature, then we were in for a very unexpected result. Absolutely all modes showed the same white point – 7200 K. It should be noted that these figures can be called satisfactory compared with the reference value of color temperature – 6500 K. Apparently, this bias can be corrected by calibration.

    The studies revealed that the developers have provided a huge amount of color temperature presets. Thus, the user can select a preset white point from 3000 to 10,000 K, adjust the color temperature by adjusting the contrast and per-channel offset base colors, and turn off all color signal processing, image showing “as is”. We did not explore all possible options, but only measured the performance presets “Installation” with a value of 6500 K, “User” and “straight.”

    So, as in the case of the picture presets, preset color temperature indicators have been very close. Nevertheless, the category leader in measuring the brightness became preset “Direct.” Its brightness was 415.9 cd/m2. Followed by a preset “Installation” – 414.4 cd/m2. And closes the list of preset “User”. Its measured brightness was 414 cd/m2.

    Black level decreased only during measurements preset “User”, and that is what has defined its leadership in the category measured contrast. Result – 760:1. Excellent! Two other pre-shared the following line in the list, as their ratio between white and black was 730:1, which can also be considered a good indicator that quite a bit behind the passport 800:1.

    In the category of color temperature is about the same situation, however places are distributed as otherwise. Presets “Installation” and “User” made ​​the same way – with a score of 7400 K, and the preset “Direct” showed a temperature of about 7500 K. All these results are quite far from the standard 6500 K.

    Frankly, all previous measurements suggest that the preset modes do not differ from each other. However, it is not – it is the measurement step gamma curve are the main differences between presets and manifested most clearly. Best addressed mode sRGB – his schedule almost coincided with the reference curve. Slightly worse than the preset proved himself a “standard”, the third place was preset “Color.”

    With regard to the stability of the color temperature, here, by contrast, has shown himself mode “Color.” Its range of values ​​was only 160 K, which can be called simply an excellent result. The remaining two presets demonstrated the stability of the white point at 300 K, which is also a great indicator.

    Developers gave users a choice of five coefficients of the transfer function – “standard”, “1.8”, “2.0”, “2.2” and “2.4” – and we have to explore them all. After analysis of the results revealed that the best reference curves correspond to the preset schedule “2.2” and “2.4”. Mistakes are certainly present, but any of the curves can be used both for work and for calibration. For further measurements, we focus on the meaning of “2.2”, since in this case the variation of color temperature less.

    Analysis revealed almost complete identity of measurements of color coverage of all modes. For example, presets “Standard” and “Color” showed many shades corresponding to 94% of the sRGB color space and 73% of AdobeRGB, and color gamut sRGB preset to 94% of the sRGB color space and 72% AdobeRGB. These are good results.

    Spread of values ​​in the category of precision display of individual colors to be a rather significant. Proved to be the best to sRGB. Its mean deviation was only 1.87. This is a great indicator. Followed by a preset “standard.” His result was 5.79, which is satisfactory level. And closes the list of preset “Color”, ΔE which appeared at 10.01. This is too much.

    ASUS PQ321QE, color accuracy in different modes
    Mode Standart Color sRGB
    Minimum 0.27 0.2 0.3
    Maximum 10.5 16.14 4.63
    Average 5.79 10.01 1.87

    Hardware calibration

    So, at the first stage of research, we studied all preset modes monitor with default settings, and then further measured all the options preset color temperature and gamma curve parameters in the user preset. Based on these studies, we chose the combination of settings that will be used for further measurements and calibration mode “Standard” preset color temperature “User” and the preset transfer function “2.2.”

    Analysis of the calibration process allows that the results were outstanding. For example, ΔE was reduced from 5.79 to 0.77. Excellent! Thus, our guest today can rightly be considered a professional display means. White point almost exactly coincided with the reference value of 6500 K. Indicator gamma curve is getting closer to the standard: 2.22 vs. 2.09 before calibration. Color coverage has not changed: 94% of the sRGB color space and 73% of AdobeRGB. Brightness slipped slightly – from 416 to 408.1 cd/m2. When this stock luminosity compared with the declared value is still very high. Since the black level is not changed, the brightness contrast after also decreased slightly – from 770,4:1 to 755,7:1. All these results once again confirm the selection mode for calibration, because we were able to put in order the color reproduction due to a slight decline in brightness and contrast.

    Average 5,79 0,77

    The uniformity of the backlight

    Spread on the field screen brightness depending on the level of illumination was from 15 to 16%. Given the technology of light sources – is a bit much. Analysis of two-dimensional graphs luminosity distribution suggests that the brightest point is at the bottom, in the center, and by the dark – in the upper right corner.


    In the beginning of this article we mentioned the most notable and significant advantages of our guest today: a huge matrix made by technology IGZO, no less great resolution 3840×2160 and constructed to meet the highest demands of professional models. Of course, these characteristics allow the monitor to expect an equally excellent results, and in the first place – a high quality image. Decides whether our guest today with this serious problem?

    In our opinion – completely. During the measurements, the display showed the highest, sometimes even record brightness, remarkable contrast ratio which exceeds the IPS-performance models, exact schedule of the transfer function to the standard, the high stability of color temperature, as well as good color gamut. In addition, the magnificent design of the monitor allows you to fine-tune the position of the panel to work comfortably for a long time. Disadvantages, however, there are also: the color temperature of the white point, which is still far from the standard 6500 K, and the most impressive display precision of individual colors. However, these two shortcomings were easily corrected during the calibration process, and so well that ASUS PQ321QE deservedly received the title of professional display means.

    Our guest today is more reminiscent of an engineering sample for testing, a kind of demonstration of the capabilities. However, even with all these irregularities, all that can be said about the first monitor with a resolution 3840×2160 one word – it’s impressive! Yes, there are still some difficulties with support from the video card manufacturers and developers of gaming software, but we believe this is only because the model ASUS PQ321QE actually ahead of its time. This means that progress can not be stopped. Five years and such monitors will certainly become a mass product and win popularity, especially as all the prerequisites for this are available. And we have the opportunity to touch the future now.
