Our Verdict
Gigabyte AORUS FO48U OLED
ASUS ROG Swift OLED PG42UQ
The Gigabyte AORUS FO48U OLED and the ASUS ROG Swift OLED PG42UQ are both OLED monitors with a few differences. While the ASUS has a smaller screen with higher pixel density, the text clarity is just okay between each. They have different screen finishes, with the Gigabyte having a glossy screen and the ASUS having a matte screen, which reduces direct reflections but introduces haziness to the image. The ASUS also has a slightly faster 138Hz refresh rate than the Gigabyte.
