Our Verdict
ASUS ROG Strix OLED XG27AQDMG
LG 27GX700A-B
The LG 27GX700A-B and the ASUS ROG Strix OLED XG27AQDMG are both 1440p OLED gaming monitors. The LG uses a newer RGB Tandem OLED panel, which gets brighter and displays more vivid colors than the WOLED panel of the ASUS. However, the LG is inaccurate with its brightest settings, so the ASUS is more accurate while still getting fairly bright. The LG is a bit more well-rounded in terms of features, as it supports HDMI 2.1 bandwidth, so it supports more signals with consoles than the ASUS.
