Our Verdict
ASUS ROG Strix OLED XG27AQDMG
ASUS ROG Swift OLED PG27UCDM
The ASUS ROG Swift OLED PG27UCDM is a higher-end 240Hz OLED gaming monitor than the ASUS ROG Strix OLED XG27AQDMG. The main advantage of getting the PG27UCDM is that it has a higher 4k resolution for sharper text and higher-bandwidth HDMI and DisplayPort inputs. The PG27UCDM even has some extra features, like a USB hub that has a KVM switch. That said, the XG27AQDMG is still the better choice if you want something for a well-lit room as it gets brighter.
