Our Verdict
ASUS ROG Swift OLED PG42UQ
LG C2 42 OLED
The LG C2 42 OLED and the ASUS ROG Swift OLED PG42UQ are both 42-inch OLED displays with a few differences. The LG is a TV, so it has more built-in features like a smart system and image processing, but the ASUS is a monitor with a USB hub and a DisplayPort input. In terms of picture quality, they're very similar, but the ASUS gets brighter in HDR; you just need to make sure it's updated to the latest firmware for the best performance.
