Our Verdict
ASUS ROG Swift OLED PG27AQDM
ASUS ROG Swift OLED PG34WCDM
The ASUS ROG Swift OLED PG34WCDM and the ASUS ROG Swift OLED PG27AQDM are OLED gaming displays with a 240Hz refresh rate. However, the PG34WCDM is significantly wider than the PG27AQDM, so if immersion is important, you may find its wider screen creates a more immersive gaming experience. Both are fantastic for gaming and watching HDR content. The PG27AQDM works better for console gaming and is the better choice if more vivid HDR colors are important to you. However, the PG34WCDM's brighter display is a better choice if you're gaming in a room with more ambient light.
