Cooler Master Enter OLED Market with 27″ 240Hz Tempest GZ2711 Monitor

Cooler Master are entering the OLED monitor market with a model of their own in the near future, the Tempest GZ2711. It’s a 27″ sized model with a 2560 x 1440 resolution and 240Hz refresh rate, competing against models from many other manufacturers including the Asus ROG Swift PG7AQDM, LG 27GR95QE and KTC G27P6 that we’ve reviewed in this segment.
Cooler Master Tempest GZ2711 Specs
The screen is 27″ in size with a flat format, and built around an LG.Display WOLED panel like the other OLED monitors currently available in this size. It has a 2560 x 1440 resolution, 0.03ms G2G response time spec, 1.5M:1 contrast ratio, 150 cd/m2 typical brightness / 450 cd/m2 max brightness (SDR), 178/178 viewing angles, 10-bit colour depth and a wide colour gamut covering 98.5% DCI-P3 and 95.3% Adobe RGB. The screen also comes factory calibrated with a dE <2 listed.
It’s native 240Hz refresh rate is supported by adaptive-sync for VRR from compatible systems, and the screen includes certification under the AMD ‘FreeSync Premium’ tier.

HDR Capabilities
Being an OLED screen it can offer excellent HDR performance with per pixel level dimming to avoid halos and blooming, along with true blacks and a near infinite contrast ratio (depending on lighting conditions). Cooler Master do not list a peak brightness spec for HDR at this time, but we expect it to be ~1000 nits as with the other 27″ OLED monitors on the market.
Connectivity options including HDMI 2.1 and USB type-C
For connectivity there are 2x DisplayPort 1.4, 2x HDMI 2.1 (capabilities not listed) and 1x USB type-C available (with DP Alt mode and 96W power delivery). There are also 2x USB data ports and an audio output connection. There’s also 2x 3W integrated speakers for sound. Picture By Picture (PbP) and Picture In Picture (PiP) modes are also supported on the screen to handle multiple inputs.
There are some RGB lighting strips on the back of the screen as well, and the stand offers a full range of tilt, height, swivel and rotate ergonomic adjustments.

Pricing and Availability
We expect the screen to be released in Q1 although we are waiting on pricing and regional availability information.
