Our Verdict
Gigabyte G27Q
Gigabyte M27Q (rev. 2.0)
The Gigabyte M27Q (rev. 2.0) is a higher-end monitor than the Gigabyte G27Q, so it has a few more features. The main difference is that the M27Q has a USB-C port and KVM switch, making it easier to multitask, which the G27Q doesn't have. The M27Q also has Picture-by-Picture and Picture-in-Picture modes, which is something else that the G27Q doesn't have. Besides those differences, the G27Q has a bit better reflection handling and gets slightly brighter, so it's the better choice for well-lit rooms. The M27Q has better accuracy before calibration, but besides that, both monitors perform similarly.
