AOC U2879VF vs LG 27UD88-W

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 screen can be very bright, at 320 nits, above the industry average of 240 nits. This means it can be used with no problems in well lit rooms. The screen is coated with a matte finish, preventing errant glare and reflections.

The bezel is barely visible, except for the bottom part of the screen, resulting in an elegant look and an illusion that the screen is bigger than it actually is.

The settings of the monitor are adjusted using a joystick at the bottom of the monitor. It's easy to reach, precise and all the controls are displayed on the screen. The OSD menu is clear and understandable.

The LG 27UD88 offers a wide choice of connectivity options. It includes two HDMI 2.0 ports, one Display port 1.2 and USB-C port that can be used as a video input port as well. There are also two USB 3.0 ports for external hardware or media devices.

It is made from plastic, but feels robust and solid. The back is white and the foot has a silver metallic finish. The stand has a large footprint, but should fit on most of the tables and still feel stable. Overall it looks premium more expensive than it actually is.

Height and tilt adjustment can be made on this screen, although the height adjustment interval is rather small. Pivot is also available, so it can be used in portrait mode, when needed.

The monitor has outstanding sharpness, brightness, color accuracy and an almost perfect sRGB color coverage. It comes factory pre-calibrated that will satisfy most users, but there are also plenty of calibration options if needed. The viewing angles are excellent at nearly 180 degrees, meaning pictures will look good even from extreme angles, without any noticeable color distortion.

This screen suits multi monitor setups particularly well, since it has almost no visible bezels.

Users will be able to find the best preset for their specific use of the monitor as it comes with 14 different ones. These include an sRGB preset, a preset for eased reading, for color blindness, multiple broadcasting standards and gaming presets. There are also several picture-by-picture presets, but only for two inputs at once. You can make your own presets as well and switching between them is quick and easy using the joystick at the bottom of the screen.

Laptop users with USB type-C connector can transmit video signals directly to the monitor. When connected, you can also use the monitor as a USB port for data transfer as well as charge your laptop if it supports type-C charging. All of this can be done simultaneously through just one wire.

The screen can produce 1.07 billion colours and covers 99% of the sRGB color spectrum. This means great performance in nearly every situation, from gaming to professional photo/video color correcting and post-processing. Color accuracy is one the best among its competitors, and is on par with more expensive monitors. This monitor comes factory calibrated for accurate color accuracy, but can be further adjusted with LG’s True Color Pro calibration software.

Even the most experienced gamers will like this monitor as27UD88 has one of the lowest input lags currently available for 4K display, measuring only at 9,8ms, making it ideal for virtually lag free gaming. The pixel response time measures at 5ms that is not the best result, but still is really good and should not cause any noticeable problems for majority of the users.
