The AOC U2879VF is a 28 inch 4K (3840 x 2160) monitor with support for HDMI, VGA, DVI and DisplayPort.
Pro Extremely sharp
The AOC U2879VF uses a 4K-display with a resolution of 2160 x 3840 pixels, which is four times the amount of pixels of a Full HD display. This results in an extremely sharp image and overall great image quality. In terms of pixel density (measured in pixels per inch), this display measures at 163 ppi. For comparison - a Full HD display of the same size will only achieve half of that - 81.5 pixels per inch.
Pro Varied inout options
This monitor has four different inputs–DisplayPort, HDMI 2.0, DVI and VGA. You can even view the displays from two inputs simultaneously. Although DVI and VGA connections can be useful to connect older laptops or PCs with old graphic cards, they do not support 4K signal transmission.
Pro Excellent screen uniformity
The AOC U2879VF has excellent screen uniformity, both in terms of luminance and color. In fact, this panel scores extremely well with a luminance deviation of 6.32 percent - which is better than most displays with IPS panels. No backlight bleeding or hotspots are present.
Pro Excellent grayscales in sRGB preset, great for graphical work
When using the sRGB preset - which is particularly useful for graphical editing - the grayscale error readings of the U2879VF are quite low for a relatively inexpensive panel. The error measures was 0.93 Delta E - that's only a tad worse than specific graphical displays which retail for a much larger price. For comparison, a standard 28" TN panel measures at 1.60 Delta E. (Lower is better.)
Con Maximum refresh rate limited to 75 Hz, less ideal for fast-paced action
The maximum supported refresh rate of this monitor is 75 Hz or 75 frames per second which is a tad faster than non-Freesync monitors, but is not as good as 120 or 144 Hz displays. Especially fast-paced games benefit from a higher refresh rate, for a more fluid gaming experience.
Out of Date Pros + Cons
Con High-end GPU required in order to enjoy 4K gaming
Because 4K offers four times the amount of pixels compared to a Full HD screen, that also means your graphics card will have to work a lot harder. You'll need a high-end GPU or even multiple graphics cards in order to fully enjoy games in 4K resolution with maximum settings, although you can always choose to display in 1080p.
