Our Verdict
LG 27GP850-B/27GP83B-B
Samsung Odyssey G7 S28AG70
The Samsung Odyssey G7 S28AG70 and the LG 27GP850-B/27GP83B-B are both excellent for gaming, but they have different features. The Samsung has a 4k resolution with a 144Hz refresh rate, while the LG has a 1440p resolution and a higher 180Hz max refresh rate. The LG has a slightly better response time, especially at 60Hz, and it's better for bright rooms because it gets brighter a. However, the Samsung is a better choice for console gaming thanks to its HDMI 2.1 inputs, and it has a local dimming feature, which the LG doesn't have, but it causes blooming around bright objects.
