Product Overview

Visuals Beyond Limits

GM27-CQS is a fully featured gaming monitor with all the specifications you'd expect for a high-tier gaming monitor. Using an ultra-speed VA panel gets you extreme motion performance with deeper blacks for stunning levels of contrast. Combine this with a WQHD resolution panel, 165Hz refresh rate, 0.5ms response time, and FreeSync Premium for a premium gaming experience like none other.

Find Your Balance

Stunning visuals in game don't negatively impact your work life as well. Take the GM27-CQS as your main monitor to enjoy games and entertainment during the night and tackling spreadsheets during the day.

Sharp Details

For gaming, WQHD resolution remains the perfect balance between visual fidelity and performance. It also offers extra screen-real estate for increased multitasking efficiency. Overall, it's a great resolution at the size of 27" for whatever you throw at it.

Ultra-Speed VA Panel

GM27-CQS utilises an ultra-speed VA panel with an ultra-responsive 165Hz refresh rate and 0.5ms pixel response time. Motion performance is clearer than ever and gives you an edge in competivite games where speed is key.

Just the Right Amount of Curve

Featuring a 1500R curvature, the GM27-CQS also has just the right amount of bend for immersion without going too overboard. Having a more pronounced curvature can start to increase distortion at certain points and generally is not beneficial to content creation applications. With the 1500R curvature, games and entertainment are even more enjoyable, increasing your immersion by filling up your field-of-vision and making you feel more part of the action.

FreeSync Premium

With FreeSync Premium, you can say goodbye to in-game tearing for an extra smooth gaming experience.

Colour Space Conversion

Choose your suitable colour-space based on the scenario you encounter for even more accurate colours.

Multi HDR Mode

Select and customise your HDR profiles based on the content you play and the HDR performance you prefer.

Game Assist Functions

Gain the competitive edge with built-in game assist functions which include Timer, Crosshair, FPS Counter, and Black Stabilisation tools.

Dynamic Overdrive

Dynamic Overdrive technology delivers an upgraded response setting that dynamically adapts the tuning based on the current frame rate. This provides an even smoother, smear-free game experience than traditional overdrive modes.

Low Blue Light Mode

Low Blue Light Display mode reduces the amount of potentially harmful blue light and makes you feel more at ease during long work or play sessions.

Unique Identity

With the Cooler Master Halo ring as the base of the stand, GM27-CQS features a sleek, minimalistic design that is suitable in any environment.
