Our Verdict

Sony INZONE M9

Gigabyte M27U

The Sony INZONE M9 and the Gigabyte M27U are both 27-inch, 4k gaming monitors. However, there are a few differences between them, as the Sony has a better local dimming feature and gets brighter in HDR for an improved HDR experience. The Sony also has features made for the PS5, like Auto HDR Tone Mapping. On the other hand, the Gigabyte has an overclock feature to reach a higher 160Hz refresh rate, and it has some extra productivity features like a KVM switch.
