Our Verdict

Gigabyte G27QC

MSI Optix G27CQ4

The Gigabyte G27QC is much better overall than the MSI Optix G27CQ4, even though they each have a VA panel, 165Hz refresh rate, and 1440p resolution. The Gigabyte has a quicker response time, resulting in smoother motion, and its BFI feature flickers at a wider range. The Gigabyte also supports HDR10 and has a USB hub, which the MSI doesn't.
