Our Verdict

LG 48 CX OLED

ASUS ROG Strix XG27UQ

Although the ASUS ROG Strix XG27UQ and the LG 48 CX OLED score similarly overall, they're very different types of displays. The ASUS is an IPS monitor with a slightly higher refresh rate, lower input lag, and higher peak brightness. It allows for ergonomic adjustments, which the LG doesn't offer, and its smaller screen results in a higher pixel density, so images and text look sharper. On the other hand, the LG has an OLED panel that can produce perfect blacks, making it better for dark rooms. It also has faster response time and supports HDMI 2.1. Although the LG has wider viewing angles, colors shift quickly when moving off-center, so it isn't ideal for content creation.
