Pros
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 Fast response time, great for gaming
With a response time of just 1ms, the AOC U2879VF is one of the fastest monitors on the market. Ideal for fast-paced gaming situations such as first person shooters.
Pro Thin bezel makes it ideal for multi-screen setups
The bezel of this display measures a thin 17 mm, which doesn't only result in a smaller build, but it makes the U2879VF also more suitable for multi-display setups.
Pro Support for MHL allows you to quickly connect a media device
This monitor supports MHL - short for Mobile High-Definition Link - which allows you to connect an Android smartphone or tablet to the U2879VF monitor.
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.)
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 Great value for the money
The AOC U2879VF is a cheap Ultra HD display with good image quality, the price/quality ratio of this display is quite high.
Pro Superb color accuracy and picture reproduction
ViewSonic takes color accuracy seriously with this monitor, as it is comes calibrated out of the box. The monitor uses a 10-bit panel and can display 99% of the sRGB color range. On top of that, it has almost no issues with screen uniformity, color accuracy and gamut. This makes it great for editing photos, videos and other types of work that require accurate colors.
Pro Plenty of input options
ViewSonic has equipped this monitor with very generous input options. It has three HDMI 2.0, one DisplayPort and one DisplayPort mini. It also has four USB 3.0 ports, two of which are on the right side of the monitor for easy access.
Pro Allows you to view from four inputs at once
If needed, the monitor allows you to view from four inputs at once, or to show them picture-on-picture.
Pro Easily adjustable
Its height, swivel, tilt and orientation can all be freely adjusted, and is attachable to a VESA compatible wall mount or stand.
Pro Excellent input lag, decent pixel response time
Input lag is almost non-existent on this screen, at only 9.9ms if the “Extreme” input mode is selected. This makes this monitor among the fastest in the market. Since it uses a slower IPS panel (compared to TN panels), the pixel response time measures just 5ms, which isn’t the best, but is good for most situations.
Cons
Con Disappointing input lag
The absolute input lag measured on this display is quite high at 87 ms. Although this won't disturb casual players, it's definitely not ideal for fast-paced gaming situations - despite a fast response time.
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.
Con 4K resolution doesn't scale well with all software
Due to the native 4K resolution and the relatively small 28 inch screen size, text can be hard to read in Windows and other non-gaming environments, such as Adobe's software. Not everything scales well in 4K (yet).
Con Red is slightly under-saturated
The display suffers from a slight under-saturation of the red color, which is a caveat for some graphical applications. This also can't be fixed through software, it's a hardware limitation of the panel.
Con Doesn't offer support for VESA mounts
The design of this display is proprietary and there is no support for the universal VESA standard. As a result, wall-mounting this display isn't possible, and alternative stands aren't compatible as well.
Con Gaming presets do not bring any real improvements to the visual quality
Although there are a lot of gaming presets to choose on the monitor, they are either too bright or dark and do not bring any real improvements on the visual qualities.
