Our Verdict
ASUS ROG Strix OLED XG27AQDMG
Samsung Odyssey OLED G60SD S27DG602S
The Samsung Odyssey OLED G60SD S27DG602S and the ASUS ROG Strix OLED XG27AQDMG are both 27-inch OLED gaming monitors. If competitive gaming is important to you, then the Samsung is a better option, as it has a higher refresh rate and feels more responsive. It also has sharper text and displays a wider range of colors. However, if you're gaming in a bright room, the ASUS is a better choice, as it gets brighter, and it doesn't appear purple at all if there's a lot of ambient light shining on the screen.
