Our Verdict
Samsung Odyssey OLED G85SB S34BG85
ASUS ROG Swift OLED PG34WCDM
Both the ASUS ROG Swift OLED PG34WCDM and the Samsung Odyssey OLED G8/G85SB S34BG85 are 34-inch ultrawide OLED gaming monitors. Both monitors are superb for gaming and have incredible HDR performance. If you're looking for a smooth gaming experience, then the ASUS's high refresh rate makes it a better choice. It's also better if you want to reduce persistence blur in games, as it has a BFI feature. However, the Samsung is a better choice if rich colors are important to you, as it has more vivid HDR colors.
