Our Verdict
ViewSonic XG2431
Samsung Odyssey G4/G40B S27BG40
The ViewSonic XG2431 and the Samsung Odyssey G4/G40B S27BG40 have similar features, but the ViewSonic is better overall. Despite each having a 240Hz refresh rate, the motion handling is much better on the ViewSonic, and it has a more customizable backlight strobing feature. The ViewSonic is also better for console gaming because it can downscale 4k signals, which the Samsung monitor can't do.
