As for me, I haven’t taken the step to the dark side yet and have gone to 4K resolution on my main monitor, I’m still using 2160×1440. This is mainly because it takes a really good computer to run games properly in high resolution, and also because I usually play FPS games, where I usually lower the resolution in favor of really high frame rates. Now that I’ve recently built a new computer, thoughts of moving to a 4K monitor are starting to resurface, so I was really excited when Cooler Master’s new splashy monitor GP27U hit the newsroom. On paper it looks promising with an IPS panel, Mini-LED lighting, Quantum DOT film, HDR and all this on top of being really fast with a millisecond response time. But does all this justify the nearly £800 price tag?
As I said, Cooler Master really nailed it with the GP27U and the display has almost everything you can imagine when it comes to features and functions. There is a built-in KVM switch which is really useful if, for example, you have a home office and want to run the same monitor, keyboard and mouse on two different computers. You can easily switch between your personal PC and your work computer with the touch of a button on the screen without having to reconnect any cables. The table stand can be raised and lowered with adjustments in all directions and the base is designed like the Cooler Master logo and takes up quite a bit of space, which is something I really prefer instead of a wide and sprawling base that many monitors have. easily gets in the way of both your keyboard and mouse. The design is clean and I like the lighting on the back which can be changed to any color, but the build quality of the screen itself leaves a bit to be desired as it feels a bit plasticky for its price and I would have liked a bit more opulent material choices.
The image on this screen is one of the absolute best I’ve seen, and it would be strange otherwise considering what they put into it. Because the IPS panel with Quantum DOT film has incredibly good color reproduction right out of the box, and it feels like every pixel is hand-chiseled because the sharpness is top notch. It has Mini LED backlighting with 576 local dimming zones, and it shows in the blackness and contrast, which is really, really black when needed. However, the viewing angle is not very large, and it is not a screen where you watch a movie with a friend. But what really impresses me is the brightness, as at 1200 nits (in HDR max mode) it hurts the eyes at full brightness, which is quite unusual. Fortunately, it is easy to adjust to the right level using the on-screen menu, which is clear and simple to use.
The panel in the screen has a refresh rate of 160Hz, and it may seem a little low, but given that it has a resolution of 3840×2160, it requires a really powerful computer to come up with several images per second. Especially if you want to play with all graphics at maximum, you don’t need a higher frequency, and I think it’s hard to see the difference compared to monitors with e.g. 240 Hz. The screen’s response time should be one millisecond on paper, but it’s not quite right in reality and stops at just over two milliseconds when measuring in-game, but that’s good enough for those of you who aren’t pro gamers, and it’s not something I even noticed when playing Call of Duty: Modern Warfare II and Counter-Strike: Global Offensive. What’s really cool is that it’s a 4K screen, and games like Shadow of the Tomb Raider and Cyberpunk 2077 look magically good, and with everything on ultra, the graphics are top notch, reaching another level in the very the gaming experience with the enormous wealth of details.
The Cooler Master Tempest GP27U is a very good monitor, but it will put a big dent in your wallet and is best suited if you need to play graphics-heavy games with HDR support. It is also good as a screen to work with graphics on, but requires calibration as it is not optimized from the factory.
