Pros
Pro Excellent grayscales in sRGB preset, great for graphical work
When using the sRGB preset, which is particularly useful for color-sensitive work, the grayscale error readings of the U2879VF are quite low for a relatively inexpensive panel. The error measures 0.93 Delta E which is only a tad worse than specially-designed graphical displays which retail for a much larger price. For comparison, a standard 28" TN panel measures at 1.60 Delta E, with lower values being generally better.
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 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 at 81.5 pixels per inch.
Cons
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. Fast-paced games benefit from a higher refresh rate for a more fluid gaming experience.
