Our Verdict

BenQ EX2780Q

MSI Optix G27CQ4

The BenQ EX2780Q and the MSI Optix G27CQ4 are both very good gaming monitors with different panel types. The BenQ is a 144Hz monitor with an IPS panel with wider viewing angles, and the MSI has a 165Hz refresh rate and a VA panel with higher contrast. The BenQ supports HDR, which the MSI doesn't, and it has quicker response times, so motion looks better.
