Our Verdict

ASUS ROG Strix OLED XG27AQDMG

Gigabyte MO27Q28G

The Gigabyte MO27Q28G is slightly better than the ASUS ROG Strix OLED XG27AQDMG. The newer fourth-generation panel on the Gigabyte delivers higher HDR peak brightness, with brighter specular highlight details and more vibrant bright scenes. The Gigabyte also has a slightly faster refresh rate, but it doesn't make a significant difference.
