Our Verdict
ASUS ROG Swift OLED PG27AQDP
LG 27GX790A-B
The ASUS ROG Swift OLED PG27AQDP and the LG 27GX790A-B are both 1440p 480Hz WOLED competitive gaming monitors. The ASUS is a better choice if you're gaming in a brighter room, as it gets brighter in SDR. It also has a black frame insertion feature to reduce persistence blur. However, the LG has fewer bugs and is a better choice if you're looking for a monitor with fewer issues.
