Our Verdict
ASUS ROG Swift OLED PG34WCDM
MSI MPG 341CQPX QD-OLED
The ASUS ROG Swift OLED PG34WCDM and the MSI MPG 341CQPX QD-OLED are 240Hz 34-inch ultrawide OLEDs. The ASUS is the better option if you're playing in a room with a lot of ambient light, as deep blacks don't appear purple. However, the MSI is the better option if you want the most vivid colors.
