Our Verdict
Gigabyte M27Q (rev. 1.0)
Gigabyte G27Q
The Gigabyte M27Q (rev. 1.0) is better for gaming than the Gigabyte G27Q. It has a higher 170Hz refresh rate and a much quicker response time at 60Hz, resulting in minimal motion blur. It has a better SDR color gamut, making it a better choice for content creators, and it has a KVM feature allowing you to control two devices with the same mouse and keyboard. On the other hand, the G27Q has a bit better reflection handling and gets slightly brighter in HDR, but these are minor differences and may be hard to notice.
