Our Verdict
Gigabyte M28U
Cooler Master Tempest GP27U
The Cooler Master Tempest GP27U is better overall than the Gigabyte M28U. The Cooler Master delivers better overall picture quality thanks to its decent local dimming feature, which helps it get brighter and display deeper blacks. It also has higher HDMI 2.1 bandwidth than the Gigabyte, so your graphics card doesn't need to use compression to achieve high-frame-rate signals. On the other hand, the Gigabyte has better color accuracy, and colors don't wash out when viewing off-center like on the Cooler Master.
