AOC U2879VF vs Dell P2217H

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.

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.

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.

This monitor supports MHL - short for Mobile High-Definition Link - which allows you to connect an Android smartphone or tablet to the U2879VF monitor.

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.)

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.

The AOC U2879VF is a cheap Ultra HD display with good image quality, the price/quality ratio of this display is quite high.

The Dell P2217H offers good gaming experience for a general purpose display in this price range because of its reasonably low input lag and good motion handling capabilities.

The monitor feels responsive because of its input lag of 9.8 ms. Only gaming monitors in this price range outperform such result.

Motion looks reasonably clear because only tiny traces follow fast-moving objects on the screen. The monitor's pixels need only six milliseconds to change their color, which reduces motion blur.

This monitor doesn't put additional stress on your eyes as its backlight doesn't flicker. This is important as monitor flickering is one of the leading causes of eye fatigue.

You can leave the monitor on for long periods without having to worry about pixel damage because the Dell P2217H does not have any problems related to image retention.

You won't have any trouble setting this monitor according to the needs of your workspace since the Dell P2217H supports all of the necessary ergonomic adjustments. Additionally, you can easily change its orientation from landscape to portrait, and vice versa.

You can charge external USB devices and connect them to a computer using the monitor's USB 3.0 hub.

The hub consists of four downstream ports that are used for connecting peripherals and a single upstream port that connects the hub to a computer.

The monitor's contrast ratio, peak brightness, color accuracy, and gamma are on par with what the majority of competitors in this price range offer.

The monitor's IPS panel displays good-looking picture, with bright and saturated colors, reasonably deep blacks, and lifelike intermediate mid-tones. The colors pop thanks to the monitor's peak brightness of 250 nits. Dark scenes look pretty as the monitor's native contrast ratio of 1147:1 is high enough to make the IPS panel display good-looking blacks. The intermediate tones are well balanced as the monitor's gamma of 2.18 is only 1% away from the ideal value.

Additionally, color inaccuracies are very hard to spot because of its average color error dE of only 3.2.

While it does not excel in any aspect, the Dell P2217H has enough versatility to be a decent general purpose monitor. It features good picture quality and excellent connectivity, combined with an impressive range of ergonomic adjustments.

The monitor is also suitable for occasional, non-competitive gaming since its input lag and pixel response time are low enough to grant reasonably smooth and responsive gaming experience.
