Having a 4K monitor today is more a fad than truly practical. Offering the opportunity to design movies, games and photos at huge resolutions, 4K monitors must be on average higher than a classic full HD monitor. There's nothing wrong with that, but when your computer cannot live up to the expectations offered by such a monitor, your experience will be one largely confined to the same 1080p resolutions used before, but appear worse because the larger area of the screen.
AOC U2879VF Introduction
AOC monitor is a 4K UHD U2879VF which offers a resolution of 3840x2160 on a screen with a diagonal of 28inches, or 70 centimeters and a pixel density of 157 PPI. The device offers a dynamic color contrast of 80 million: 1 with full RGB color range by 1.07 million supported colors. With 1ms response time, the monitor will not make ghosting when playing games on it and standard 60Hz frequency is variable, thanks to AMD FreeSync technology. The frequency of the monitor will automatically calibrate framerate rendered images, thus providing a more seamless viewing experience.
When it comes to connectivity, the monitor provides VGA port, DisplayPort 1.2s (Adaptive-Sync), HDMI 2.0 (with MHL), DVI and even a 3.5mm audio jack. Like any respectable 4K monitor, U2879VF supports PIP (Picture in Picture) and Picture by Picture (PBP) modes.
AOC U2879VF pros
Perhaps the biggest advantage of the new monitor from AOC is the screen diagonal. After years of facing the same screen full HD 22-inch clearly feels it's time for a change. Eventually we are no longer in 2011 to settle for a 1080p monitor, and even more so when it comes to "classic" screen diameter. Offering a diagonal slightly larger than those already encountered everywhere, the monitor from AOC with its 28 inch feels like a true upgrade without taking up too much space on your desk.
Coming up with a large number of video ports, including VGA, HDMI, DVI, DisplayPort and MHL, it is clear that this monitor can connect both your first computer on which you have already given to you grandparents and newest smartphone equipped with micro-USB cable.
All you have to do is, however, make sure you have enabled the latest versions of DisplayPort or HDMI. Otherwise, you better move on DVI or VGA, for sure you will not like it. Frequency will remain locked on 30Hz and even if it will not bother you too much in games, working on the desktop can be an ordeal.
FreeSync from AMD is another feature that caught our attention. Aimed to transition period from computers that excel in 1080p resolution satisfactory to those that can run games in 4K resolutions, FreeSync function will allow you to play at the highest resolution available with a lag of images as small as possible.
The image quality is also a great asset of the screen. Thanks to the response time of 1ms, will not escape any detail at shooters or racing games, and colors will have a much wider range than any Philips monitor thanks to a 10-bit screen Deep Color Full RGB. In this way both games and movies viewed on the monitor will enjoy a much wider range of colors than conventional monitors could offer at full HD resolutions.
AOC U2879VF Points Against
Lack of VESA may disappoint those who sought to put a monitor on the wall. In addition to tilt the monitor front and rear, there isn't another way to reposition the monitor on the table.
AOC is a very decent monitor. Even if doesn't want to impress anyone, 4K resolution can now be a nuisance that later to become a blessing. Clearly, the major electronics manufacturers such as Samsung, BenQ, Philips and AOC rushed with 4K monitors offers at a time when consumer PCs simply cannot support such resolutions constantly. Ultimately, regardless of our opinion, investing in such a monitor would be a good choice.
