Our Verdict
LG 27GP950-B
ASUS ROG Strix XG27UQR
The LG 27GP950-B is a better gaming monitor than the ASUS ROG Strix XG27UQR. The main advantage is that it supports HDMI 2.1 bandwidth, which the ASUS model doesn't have, and it lets you take full advantage of gaming consoles or HDMI 2.1 graphics cards. The LG also has better motion handling, particularly at lower refresh rates. However, the ASUS gets brighter and has better reflection handling, making it the better choice for well-lit rooms.
