Our Verdict

MSI Optix G27C4

Samsung T55

The MSI Optix G27C4 is better overall than the Samsung T55. The MSI is a much better choice for gaming because it has a 165Hz refresh rate, a much quicker response time, a black frame insertion feature, and a lower input lag. The Samsung has a bigger screen, better viewing angles, and it gets much brighter.
