Our Verdict

MSI Optix G27C4

MSI Optix G27C5

The MSI Optix G27C4 and the MSI Optix G27C5 are two very similar monitors. They have a similar design, except the G27C5 has a stand that sits flat against the table and it's better-built overall. The G27C5 also gets brighter and it has better color accuracy. However, the G27C4 has better reflection handling and quicker response time.
