Our Verdict
ASUS ROG Strix XG279Q
ASUS ROG Strix XG27UQ
The ASUS ROG Strix XG27UQ is a bit better than the ASUS ROG Strix XG279Q. The XG27UQ has a much lower input lag when playing at 60Hz, gets brighter to combat glare, and its 4k resolution results in better text clarity. The XG279Q has a faster response time, a higher refresh rate, wider viewing angles, and better reflection handling.
