Our Verdict
Samsung Odyssey G4/G40B S27BG40
Samsung Odyssey G70D S32DG70
The Samsung Odyssey G70D S32DG70 is a higher-end monitor than the Samsung Odyssey G4/G40B S27BG40, and choosing one over the other depends on your budget. The G70D has a 4k resolution and HDMI 2.1 bandwidth, which makes it the better choice for console gaming with detailed images. The G70D also has extra features, like a built-in smart system, and it displays a wider range of colors. On the other hand, the G40B is a more basic 1080p, 240Hz monitor, and its higher refresh rate makes it a better choice for competitive gaming.
