Review: Cooler Master GM27-CQS


Brightness levels and contrast ratio

We measured 301.9 nits using the screen’s default settings. Whites are stable and perfect at around 80% brightness.

VA panels have good blacks, obviously not at the level of OLED screens. Contrast is 2310:1 (without enabling HDR) and blacks are 0.10 at 200 nits, which is a decent score for a VA panel.
