Our Verdict
ASUS ROG Strix OLED XG27AQDMG
Samsung Odyssey G70D S32DG70
The ASUS ROG Strix OLED XG27AQDMG and the Samsung Odyssey G70D S32DG70 are both gaming monitors. The ASUS is the better option if you only plan to game on the monitor, as it displays far deeper blacks, a wider range of more vivid colors, highlights that pop, and significantly better motion handling. The Samsung is a better option if you plan to use the monitor for work as well as gaming, as it doesn't have any risk of burn-in with static elements.
