Cooler Master Tempest GZ2711 OLED 240Hz Gaming Monitor Review

Display Analysis
The colour gamut is exceptional, with Cooler Master rating the display at 98.5% DCI-P3, 95.3% Adobe RGB, and we got a little better on the Adobe and a little lower on DCI-P3, but this would fill out when testing in HDR and this test is in SDR, either way, this is an exceptional result.
Gamme is a fraction off, nothing noticeable to the human eye, and close enough to get a clean bill of health.
The grey ramp looks good, with very little deviation and only a little above the target 6500K, but the dimming feature of this monitor throws this out so is more accurate with that disabled, but for most uses, you would want this enabled anyway.
The colour accuracy is very good, with Cooler Master claiming an average of under 2 Delta-E and that certainly holds true at 1.6, despite the obvious 3F test rocking up at 8.5. Now, this isn’t actually true, and is a misreading due to the calibration using a full-screen bright image and the dimming feature of the monitor kicks in to protect the panel.
If I disable this feature, the 3F test is now under 2 Delta-E, but interestingly the average is actually higher, but still, anything under an average of 3 Delta-E is regarded as excellent.
