Our Verdict
Samsung Odyssey G5 C27G55T
MSI Optix G27CQ4
The MSI Optix G27CQ4 and the Samsung Odyssey G5 C27G55T are both good gaming monitors. They each have a VA panel with a 1440p resolution, and they offer similar features, but the MSI has a 165Hz refresh rate compared to the Samsung's 144Hz. The MSI is also flicker-free at all brightness levels, while the Samsung flickers at lower brightness levels. The Samsung supports HDR, which the MSI doesn't, but it doesn't add much because it can't display a wide color gamut.
