The LG 27GP850-B is okay for console gaming. It can’t take full advantage of the Xbox Series X|S and PS5 as it lacks HDMI 2.1 bandwidth and has a 1440p resolution, but it still works well with the consoles. That said, it offers good gaming performance with a fast response time and low input lag for a responsive feel. Unfortunately, it has limited picture quality, especially in HDR, as it has a low contrast ratio and lacks a local dimming feature to further improve the picture quality.

It overcomes glare in a bright room, with great peak brightness and good reflection handling. It displays a wide range of colors in SDR, which is great if your work requires accurate colors, with excellent accuracy before calibration. While it has good overall ergonomics, it doesn’t offer any swivel adjustment, making it difficult to adjust to your preferred position.
The LG 27GP850-B is decent for media creation. The large screen makes it easy to see more of your work at once, and it has good text clarity. It’s also ideal for sharing your screen with others thanks to its wide viewing angles, though the stand can’t swivel. It has great gray uniformity, exceptional gradient handling, and displays a wide range of colors in SDR, ensuring content looks accurate. It handles glare effectively, with great peak brightness and good reflection handling, but it doesn’t look as good in a dark room as deep blacks appear gray, and the screen looks cloudy.
The LG 27GP850-B has good brightness. It gets bright enough to fight glare in a well-lit room, but it fails to make highlights pop in HDR.
The LG 27GP850-B has a great overall response time. It maintains its response time consistently fast across its entire refresh rate range. While fast-moving objects look sharp, it doesn’t eliminate all motion blur and inverse ghosting.
The LG 27GP850-B is terrible for HDR. It has a low contrast ratio and lacks a local dimming feature to improve the picture quality in HDR. It also has limited HDR color volume as it can’t display bright and dark colors really well.
The LG 27GP850-B has okay SDR picture quality. It’s mainly limited by its low native contrast ratio, so blacks look gray in the dark, and it has disappointing black uniformity as there’s clouding throughout.
