Our Verdict
Gigabyte G27Q
Samsung Odyssey G5 C27G55T
The Gigabyte G27Q is better than the Samsung Odyssey G5 C27G55T because it has a better response time that results in a clearer image with a shorter blur trail behind fast-moving objects. It also has wider viewing angles that make it easier to share content and gets significantly brighter to combat glare. The Gigabyte can display a wide color gamut for HDR, but the Samsung has a much better contrast ratio to produce deeper blacks.
