Summary
I’ll try to be brief today. Therefore, I can only recommend everyone to read through the article. The Cooler Master Tempest GP27U comes with one of the best and most versatile IPS panels from AU-Optronics. The Quantum Dots make it possible that you can get up to 87 percent Rec. 2020 color space coverage. That is already a lot. The advantage, however, is that you can work in three color spaces without having to create ICC profiles.
So, if you don’t only want to gamble, but also have to edit pictures and videos, you should add the GP27U or GP27Q to your wish list. You get a UHD monitor that makes it possible to play with high frame rates in UHD in the future thanks to the 160 Hz. At the same time, you also get a razor-sharp resolution and a minimum of color accuracy to work productively with it. With a colorimeter, you can set the white point in the User1 menu – Color Space sRGB – Color Temp. User – once correctly and it automatically fits for Adobe and DCI-P3. Color Space Auto or Rec. 2020 unfortunately does not work with the D65 settings.
Additionally, the customer can access real HDR hardware to get even more out of the gaming experience graphically when gaming. Thanks to the mini-LED FALD backlight, you get true HDR. Thanks to Cooler Master for giving you full access to white point control in every situation. No matter if it’s SDR, HDR or a color space preset. You can adjust everything the way you want.
Conclusion
Good response times, no perceptible overshoot and awesome IPS colors form the basis for a really awesome UHD gaming experience. In addition, there are the three factory-calibrated color spaces, which certainly fit as exactly in a new product as they did in my first sample – before the “update drama” started. For a current price of 899 Euros, the GP27U is certainly no bargain. However, it has a lot more to offer than most other UHD monitors in the league. I assume that the price will drop significantly when availability increases. Because that is currently the price driver.
The real HDR hardware has a latency disadvantage compared to an OLED, but surely no one will play CS:GO etc. competitively in UHD. Or will they? For true gaming connoisseurs and HDR enthusiasts – the GP27U is my current “all-purpose weapon recommendation” and is, on balance, even better than the PG279QM in many areas. The question remains: Is the GP27U a real OLED alternative?
Yes, and no. The GP27U has its advantages where an OLED monitor has its disadvantages. With the GP27U, you get an IPS panel with RGB subpixel layout. Text rendering – not an issue. Risk in terms of burn-in – does not exist. Peak brightness in HDR – especially with an APL greater than 10 percent. Which OLED panel is capable of nearly 900 nits at 100 percent window size? Correct – none! At the end of the day, can the GP27U deliver the same contrast in SDR and HDR as an OLED panel? No.
Even though Cooler Master’s attempt – to create the eierlegende Wollmilchsau – has only succeeded to a certain extent. For me personally, the GP27U offers a good balancing act between gaming, working and HDR content. Especially if you depend on a very high resolution. A 32-inch version of the GP32U would certainly be a super cool addition to Cooler Master’s portfolio. I would also like to test it before the launch!
If the GP27U is currently too expensive, you can also go for the GP27Q. The GP27Q is basically the same monitor, but with QHD resolution (2560 x 1440p @165 Hz). It currently costs only 599 Euros and outshines all other monitors in its class. You won’t find real HDR hardware for this price in this class.
I’ll say goodbye to my vacation and wish the readers – who are planning the same – a pleasant time. I’ll be back in two weeks and then I’ll take a closer look at the LG 45GR95QE (more or less the Corsair Flex – without Flex). In addition, there is the BenQ Zowie XL2566K, the eSports rocket. I’ll take a closer look at the latencies with various GPUs in FHD resolution. We’ll also measure the latencies with LDAT. So, that was quite short… Uh, oops!
To Cooler Master directly: Many thanks for the good cooperation over the last eight months. Please continue to be so meticulous on the issues and especially establish a strict quality control at the manufacturer KTC.
The monitor was provided to me by Cooler Master without obligation – for testing purposes. There was no influence on the tests and results. There was also no compensation for expenses and no obligation to publish.
