We know LG for its sleek aesthetics, and the LG 27UN850-W’s design confirms a long tradition of looking great. The 27-inch UHD (3,840-by-2,160) panel is enclosed in a bezel-free white cabinet with black trim.

Setup And Settings

Like most LG gaming screen monitors, the LG 27UN850-W utilizes a four-way joystick to get to and explore the settings menu. You can use the joystick to change input sources, activate the game mode, and turn the monitor on/off. Additional settings include brightness, contrast, color temperature, and black stabilizer. There are a total of 14 picture presets on this monitor, including Reader, sRGB, Color Weakness, and SMPTE-C, to enhance the viewing experience.

For gamers, there are three gaming presets (two FPS and one RTS), two custom presets, and the general calibration presets. If you work a lot, you have a choice of the 2-screen split, 3-screen split, 4-screen split, 6-screen split, and 8-screen split, but most of these options go well beyond the basics. Operating system supports. You also have a picture-in-picture (PIP) option, which you can use for productivity tasks.


The LG 27UN850-W easily takes its place among the favorites in the gaming category with AMD FreeSync and a slew of features that help it improve the gaming experience. Being an Ultra HD panel, it is limited to a refresh rate of 60Hz, which is typical of all Ultra HD panels available right now. Despite this, it offers relatively low input lag and fast response times, further enhanced by overdrive-reducing motion blur. In fact, a lag time of 61ms is right for casual gamers, however, pro gamers are higher served by the quicker refresh rate.

Keeping that 60-fps limit in mind and with a mid-level graphics card, the LG 27UN850-W runs on modern titles like Crysis 3 (PC) and Grand Theft Auto V (Sony PlayStation 4) without any obvious ghosting or tearing artifacts. Provides fluid action. If you enable FreeSync, your game looks quite smooth.

As a professional monitor, the LG 27UN850-W checks essential boxes like Ultra HD resolution and impressive handling of HDR 400 signals, and decent film cadence. Notably, it won’t render your images with full contrast, it still does a respectable job at improving the scene with added dynamic range.

For a professional use monitor, there are two aspects missing here, the obvious one being DCI-P3 color and, although the factor feature sheet shows spot-on gamma, grayscale, and color, it does not specify which mode was tested. Was.

Input Lag

Input lag (the time it takes for a monitor to respond to controller commands) came in at a speedy 9.8 milliseconds, a few seconds behind our fastest monitors, the BenQ XL2430T and BenQ SW2700PT, both at 9.5 milliseconds. The 27-inch monitor consumes 40 watts of power once set to the FPS1 preset and 27 watts of power once set to the sRGB preset. It’s additional energy-efficient than the Acer Nitro XV272U and Viewsonic VP2780-4K, at 41 watts and 31 watts.

Our Rating | Excellent

As mentioned, the LG 27UN850-W is HDR certified, however in contrast to its different relative to the LG 27UK850-W that supports HDR10, this panel rocks VESA DisplayHDR 400 and 99% sRGB color gamut coverage.
