Our Verdict
ASUS ROG Strix XG279Q
ASUS ROG Strix XG27AQ
The ASUS ROG Strix XG279Q and the ASUS ROG Strix XG27AQ are very similar monitors with similar specs. The biggest difference is that the XG27AQ has a simplified stand, and its local dimming is a little less aggressive. The XG27AQ shows less backlight bleed, resulting in better black uniformity, but this is something that can vary. The XG27AW also has slightly wider viewing angles. The XG279Q, on the other hand, gets brighter overall in SDR and HDR, so it can fight glare a little more easily and can bring out more highlights in HDR content. Otherwise, they perform very similarly and both are among the better gaming monitors we've tested, so you can't really go wrong with either.
