Our Verdict
Samsung Odyssey OLED G85SB S34BG85
Corsair XENEON 27QHD240
The Samsung Odyssey OLED G8/G85SB S34BG85 and the Corsair XENEON 27QHD240 are different types of OLEDs. The Samsung has an ultrawide display with a QD-OLED panel, allowing it to get much brighter with more vivid colors than the Corsair. On the other hand, the Corsair has a higher 240Hz refresh rate, which is ideal for competitive gaming, and it supports 4k signals up to 120Hz from the PS5 and Xbox Series X|S, which the Samsung monitor can't do.
