Our Verdict
Acer Nitro XV282K KVbmiipruzx
MSI Optix G321CU
The Acer Nitro XV282K KVbmiipruzx is better for gaming than the MSI Optix G321CU. Motion handling is much better on the Acer as there's less smearing and blur trail with fast-moving objects. The Acer also has much better ergonomics and wider viewing angles than the MSI, so it's the better choice for co-op gaming. However, the MSI has the full 48 Gbps bandwidth of HDMI 2.1, while the Acer is limited to 24 Gbps, so your graphics card doesn't need to use compression for demanding signals.
