Our Verdict
Samsung Odyssey OLED G85SB S34BG85
MSI MPG 341CQPX QD-OLED
The Samsung Odyssey OLED G85SB S34BG85 and the MSI MPG 341CQPX QD-OLED are 34-inch QD-OLED ultrawide gaming monitors. For most people, the MSI is the better option, as it has a higher refresh rate for smoother motion, a KVM switch, and HDMI 2.1 bandwidth. That said, the Samsung is an excellent monitor, and if you can find it for less, it can be a great choice.
