Our Verdict
MSI Optix G27C4
MSI Optix G27CQ4
The MSI Optix G27CQ4 and the MSI Optix G27C4 are both very good gaming monitors. They're built nearly the same, and each has a VA panel with a 165Hz refresh rate. The main difference is that the G27CQ4 has a 1440p resolution, while the G27C4 is limited to 1080p. The G27CQ4 is a better choice for well-lit rooms because it gets much brighter. However, the G27C4 delivers much smoother motion thanks to its quick response time.
