Our Verdict
Samsung Odyssey G3 F27G35T
Samsung Odyssey G4/G40B S27BG40
The Samsung Odyssey G4/G40B S27BG40 is a higher-end monitor than the Samsung Odyssey G3 F27G35T, and it's better for gaming. The G4 has a higher 240Hz refresh rate, ideal for PC gaming, and has much better motion handling and faster response time. The G4 is also better to use in bright rooms as it gets brighter and has better reflection handling. The G4 supports HDR, which the G3 doesn't, and it has a different panel type with wider viewing angles. However, the G3 has a better contrast, making it a better choice to use in a well-lit room.
