The path 4K to the usual user is long and thorny, despite all the attention that is surrounded. Everything is in order with the monitors themselves, but there are still few films in this format, the players have not reached retail shelves yet, and the programs are not all optimized … Buying a monitor with a resolution of 3840 x 2160, you need to remember that the productivity of the rest of the system must correspond. Fortunately, the 28-inch monitor AOC U2868PQU is quite humane to finance the upgrade of the video card. In addition, for many years, the resolution of such a display will remain relevant and will be the pride of its owner.
AOC U2868PQU design is quite classic: black plastic with a textured surface, rounded corners and standard width of the frame around a slightly drowned screen of the screen plane.
The screen has a matte coating. The TN type panel is used here, which positively affects speed-the response time (Grey-to-Grey) is 1 ms. The use of an honest 8-bit matrix combined with FRC (Frame Rate Control technology, also called Disering) allows us to declare 1.07 billion support (!) flowers instead of the usual 16.77 million. Brightness 300 KD/m2 allows you to work at the monitor in well -lit rooms. Contrast 1000: 1 standard, but quite sufficient. The viewing angles are typical for TN – 178/170 degrees.
The most interesting characteristic of the display is its resolution: 3840 x 2160 pixels – this is four times more than Full HD. By the way, with a diagonal of 28 inches, the density of pixels comes out as much as 157 pixes/inch, that is, almost like smartphones. Another important parameter is the update frequency, which is honest 60 Hz when connecting via Display Port. This is important because some budget 4K monitors give such a permit at a frequency of 30 Hz-in this case, you can forget about games.
AOC U2868PQU provides complete freedom in the connection options: there are ports D-Sub, Dual-Link DVI, HDMI and Display Port. However, due to restrictions in the standards themselves, the frequency of update 60 Hz can only be obtained through Display Port-for full work with 4K, the video card must have such a connector. The remaining ports are useful to connect other signal sources.
The monitor can work in the “picture in the picture” and “picture next to the picture”, that is, simultaneously give a signal from two devices. Taking into account a large diagonal and huge resolution, this function is of great importance. The HDMI port with MOBILE High-Definition Link is useful users of Android devices-with it you can directly broadcast the contents of the smartphone or tablet for a large screen.
The manufacturer for conscience worked on the stand. It allows you to adjust the height of the monitor by 130 mm, change the angle of inclination (from -5 to +21.5 degrees vertically) and even turn the screen 90 degrees. From the portrait regime, the benefits will be in multi -screen configurations: AMD Eyefinity and Microsoft Flight Simulator fans will surely be appreciated. Finally, if you want to mount the panel on the wall, you can use the standard Vesa mount. All connectors are available on the side, so connecting cables to the monitor hanging close to the wall will not be difficult. And if the monitor still stands on the table, then do not ignore the cable loop on the back of the display: it will help restore order on the desktop and carefully lay the wires.
The presence of an audit suggests that the monitor can reproduce sound. Built-in 3-watt speakers will not surprise anyone with acoustic capabilities, but if you wish, you can do without multimedia acoustics on the table. Plus, the audio output can be used to connect headphones: reaching the monitor is much easier than to the system unit.
The manufacturer endowed the U2868PQU with a full-fledged USB-concentrator for four ports: Two USB 2.0 and two USB 3.0 (one of them supports the function of fast charging of connected devices). All USB connectors are hidden behind the right edge of the screen. Color coding will help not confuse the port type: black – usb 2.0, yellow – USB 3.0 with Quick Charge, blue – just USB 3.0. There is also a square “incoming” generation of generation 3.0, through which it is necessary to connect the monitor to the PC for the work of the hub.
Software

The touch buttons of monitor control are concentrated in the lower right corner of the frame. The menu consists of six items through which the numerous parameters of the display are configured.
The “Brightness” section allows you to adjust the brightness, contrast, gamut, choose one of 6 pre-installed eco-mode, as well as enable the function of dynamic contrast or overdrave.
The “Image Settings” section controls the sharpness, the image of the image on the screen horizontally and verticals, as well as synchronization parameters to reduce possible interference.
In the point “Flowers Settings” you can configure the color temperature, select one of the 5 available flow modes or manually set the coefficients of separately increased red, green and blue.
The “Improvement” menu is responsible for individual brightness settings and contrast for the screen chosen by the user – this can be very convenient for working with several windows of different programs at the same time or “Pictures in the picture”.
The neighboring section “Picture in the picture” allows you to choose the sources of the signal for the main and additional screens, configure the size and location of the second screen, and also switch the sound between the main and secondary sources.
The “Express menu settings” tab controls the menu itself, and also makes it possible to adjust the speed of the Display Port and enable a reminder of the need to make a break after 1 hour of work is a very useful and important function.
Finally, in the “Additional Settings” section, you can choose a signal source (Display Port/HDMI/DVI/D-SUB), configure the automatic shutdown timer, select the image format, enable DDC/Ci support or reset all the settings for factory.
This is not to say that using the menu is so convenient – this is the technology of the last century. Therefore, AOC has developed the I-Menu program, which duplicates all the features of the screen menu, but at the same time simple and pleasant to control. In addition, the software includes E-Saver and Screen programs+. Using the first, you can control the monitor turning off in different modes, and the second to break the desktop into several panels.
Testing
Let me remind you once again that for a comfortable game in resolution 4K the video card should be at least the GeForce 780 Ti or Radeon 290X class, and the monitor is connected through the DisplayPort connector. Since the system will have to calculate four times a more image than in FullHD, even such resources may not be enough – the SLI or Crossfire video cards in the SLI or Crossfire mode will be in handy if you plan to get stable 60 FPS.
Impressions from 4K, of course, mass. It seems that the monitor is much more than it actually is – so many windows are placed on one screen. You get used to the good quickly: you can simultaneously hold the browser open, Skype and photoshop. By the way about the latter-the monitor allows you to edit 8-megapixel photos on a 1: 1 scale.
If you start the film in 4K, it is found that the usual FullHD is actually not so detailed … It is a pity that so far there is not much content as we would like. But in the future films there will be more and more, and they themselves are more affordable.
In games, if there is enough computing power, the effect is even more impressive. The good news is also that the modes of full -screen smoothing and anisotropic filtration become almost unnecessary. Usually they noticeably decorate the picture, but also reduce performance – and in resolution of 2840×2160 the problem of uneven edges of models and shadows solves by itself, the pixels are so small that this is not visible.
The quality of the image of the AOC U2868PQU is very good, as for a monitor with a matrix type TN. The margin of brightness is enough for adequate behavior in different lighting, the backlight is uniform, the colors are displayed correctly. "Light black" color – typical for TN, but does not cause discomfort. When looking at the screen on the side, the brightness drops approximately when the angle is 45 degrees – with ordinary use, everything is fine.
In fact, there is only one obstacle before buying AOC U2868PQU, like any other 4K monitor-this is the insufficient power of the computer to which you are going to connect it. If you are sure that the PC configuration will pull your favorite games in resolution of 3840×2160 – there are no objective reasons not to buy a monitor of this class now.
AOC product pleased with good behavior in games, a combination of technical characteristics and humane price. At the time of testing, an average of 35,000 rubles is asked for it. Given how many years 4k will remain an actual standard, such a purchase will be an excellent back for the future, and now it will allow you to feel yourself on the crest of a technological wave. By the way, an extensive three -year guarantee from the manufacturer also adds arguments in favor of this device.
