Cooler Master Tempest GP27U 4K Mini LED Monitor is now available

Cooler Master GP27U 4K Mini LED Monitor

Many mini LED monitors are not yet commercially available. Cooler Master is now saturating the market with its 27 inch 4K monitor GP27U, a 4K 160Hz gaming monitor with 1,400 nits of bright mini-LED backlighting.

4K Quantum Dot Mini LED monitor under $1,000 currently corresponds to the cheapest monitor that you can get with mini LEDs in a 4K resolution, which puts it within reach for gamers and content creators. Apple’s Studio Display with a 5K resolution costs about twice as much (approx. $1,500 on Amazon), while mini-LED displays from the competition cost around $3,000, such as Asus’ ROG Swift PG32UQX.

Nevertheless, no compromises have to be made when it comes to equipment: Thanks to the built-in mini-LED technology, the Cooler Master GP27U achieves a brightness of almost 1,400 nits. The contrast is an average of 1,000:1, but with activated local dimming with 576 zones, measured by Techtesters at 2,371:1. Unlike many other monitors, the local dimming can also be used in SDR mode.

Techtesters measured the illumination as very even at 99%, with no visible backlight bleeding. In addition, according to these measurements, the color accuracy is on a decent level, with an average DeltaE value < 2 for colors and grayscale of the three color spaces sRGB, AdobeRGB, and DCI-P3, which are also 100%, 97.5%, and 96% respectively. Individual colors deviate slightly, at least without calibration, in the test model from Techtesters.

Nvidia G-Sync and AMD FreeSync are also included, plus there’s a true HDMI 2.1 port that supports 4K at 120Hz, which is useful for things like the XBOX Series X or the PS5. Of course, the response time is also interesting for gamers. Techtesters measured it at 11 ms (Rise+Fall). While other monitors are faster here, the latency can be reduced to 7.9 ms using the Overdrive function without any overshoot.

Tempest GP27U price and availability

The best 4K monitor for gaming under $1,000 with Mini LED Quantum Dot technology has been available in stores for a short time, but is not yet listed everywhere and is also slightly above the RRP, for example, at for $991.58. There are simply no alternative 4K gaming monitors with mini LEDs in this price range, and future mini LED monitors, such as the 35-inch ViewSonic Elite XG341C-2K with 200 Hz and twice as many dimming zones, should also be available and cost $1,500.
