Our Verdict
ASUS ROG Strix OLED XG27ACDNG
ASUS ROG Swift OLED PG27UCDM
The ASUS ROG Strix OLED XG27ACDNG and the ASUS ROG Swift OLED PG27UCDM are both QD-OLED gaming monitors. They're different in a few ways, though, as the PG27UCDM has a higher 4k resolution for sharper images and text, while the higher 360Hz refresh rate on the XG27ACDNG delivers a smoother feel. While they have many of the same features, the PG27UCDM has a few extra perks, like a DisplayPort 2.1 input and Dolby Vision support, so choosing between the two also depends on if you want these features.
