Our Verdict
Samsung Odyssey G3 S24AG30
Samsung Odyssey G4/G40B S27BG40
The Samsung Odyssey G4/G40B S27BG40 is a higher-end version of the Samsung Odyssey G3 S24AG30, so it has a few more features. The main difference is that the G4 has a higher 240Hz refresh rate compared to the 144Hz refresh rate of the G3, and it has much better motion handling too. They also have different panel types, with the G4 having wider viewing angles and the G3 having a higher contrast, making it the better choice for dark room gaming.
