Our Verdict
ASUS ROG Strix OLED XG27ACDNG
Gigabyte MO27Q28G
The Gigabyte MO27Q28G is a slightly better monitor than the ASUS ROG Strix OLED XG27ACDNG. The Gigabyte gets a lot brighter, so it can handle more glare in a bright room, and it delivers a more impactful HDR experience. The ASUS has better color volume, though, as very bright colors are slightly washed out on the Gigabyte. The ASUS also has a higher max refresh rate, which helps improve motion clarity a bit.
