Our Verdict
Gigabyte M32UC
MSI Optix G321CU
The Gigabyte M32UC is better for gaming than the MSI Optix G321CU. While both monitors have smearing with fast-moving objects, the Gigabyte has less overshoot and improved motion handling, particularly at high refresh rates. The picture quality on the Gigabyte is also better as it gets much brighter, and it has a better contrast ratio. On the other hand, the MSI has the full 48 Gbps bandwidth of HDMI 2.1, while the Gigabyte is limited to 24 Gbps, so your graphics card doesn't need to use compression when sending high-bandwidth signals.
