Our Verdict
MSI MEG 342C QD-OLED
Corsair XENEON FLEX 45WQHD240
The MSI MEG 342C QD-OLED and the Corsair XENEON FLEX 45WQHD240 are both fantastic OLED gaming monitors with a few differences. The MSI has a smaller screen, but because they have the same resolution, the Corsair has lower pixel density and worse image sharpness. The MSI also has a QD-OLED panel that gets brighter and delivers more vivid colors than the Corsair for an improved HDR experience. While they each have USB-C ports, the MSI delivers higher power delivery, making it easier to charge power-hungry devices. On the other hand, the Corsair has a higher 240Hz refresh rate and a bendable screen that lets you adjust its curve to your liking.
