Cooler Master Tempest GP27U Review (Mini-LED 4K/160Hz)

Rating: 8.0.

Cooler Master is still a relative newcomer to the monitor market but we've been reasonably impressed with the screens we have already reviewed from the company. The Tempest GP27U is a clear step up for Cooler Master however, with this display offering a 4K/160Hz IPS panel, enhanced with a Mini-LED backlight that offers 576 dimming zones. Mini-LED displays have historically been quite expensive, but with the GP27U retailing for £800 here in the UK, could this be a winner?

On paper, there's a lot to like about the Cooler Master Tempest GP27U. High refresh-rate 4K is one thing, but offered in combination with a fast IPS panel and a Quantum Dot filter certainly sounds like a recipe for success. Factoring in the aforementioned Mini-LED backlight, Display HDR1000 certification and HDMI 2.1 support, it seems that for £800 Cooler Master is offering a heck of a lot of monitor for the money.

We're here to find out exactly how good this screen really is, taking a look at the design, OSD, panel performance, response times, latency and more… so without further ado, let's dive in.
