The best gaming monitors when you want the most contrast possible from an LCD panel. Due to its small size, the backlight can be dimmed in more places. There are more than 1,000 dimming zones on bigger screens, but only 576 on 27-inch 16:9 panels. When there are more zones, you can control smaller parts of the image better.
LEDs can be turned off completely, which makes the black levels low enough to be mistaken for OLED, which means high contrast. Some LED monitors have an infinite contrast for both SDR and HDR content when local dimming is turned on. As cutting-edge technology, mini LED has been very expensive, but a few 4K monitors have dropped below $1,000.
One that has a beautiful picture because it has a wide range of colors and a bright backlight, but has faster frame rates than 4K. Cooler Master has made something new with a QHD panel that is better than any 4K display in terms of image quality while being faster and less expensive.

Cooler Master Tempest GP27Q review: Design and Features

The Cooler Master Tempest GP27Q has a unique design that strikes a nice middle ground between understated and flashy. The matte black exterior conceals dazzling RGB lights, perfect for customers who wish to create a custom lighting scheme. Bezels are absent from the design of this model, but inner borders are present.
Even while the foundation is larger than the ones we’ve seen in prior releases, it’s not enormous in size. The sturdy build suggests it will last, but some gamers worry it won’t be convenient to use on the go. Keep in mind that even if disk space is really restricted, it can still offset some of your larger peripherals.
The brand’s competence in making high-end luxury equipment for the PC and gaming markets shows in the excellent construction of their products. The plastics utilized are strong and thick, and there are no obvious flaws whatsoever. The provided stand is sturdy and secure, preventing the display from sagging or shaking even under intense pressure. You can buy this gaming monitor from its official website.
Cooler Master Tempest GP27Q review: Display and Performance

The 27-inch Cooler Master Tempest GP27Q has a 165Hz refresh rate, a 1ms response time, and a resolution of 2560 x 1440 on its IPS display. The contrast ratio is stated to be 1000:1, and the backlight has an output of 600 cd/m2 with a peak of 1200 cd/m2. HDR 1000 capability is normally only seen on expensive 4K monitors, however this model is capable of it.
Since the 1440p resolution is neither too soft nor too sharp, it is ideal for 27-inch screens. While it excels in the office and simple chores like reading and browsing, games and movies still require greater realism. Given the proliferation of 1440p-capable graphics cards, this is the ideal spot for monitors right now.
For vivid gaming and movie viewing, the Cooler Master Tempest GP27Q supports gamuts greater than 100% sRGB and 98% DCI-P3. Yet, the high deltaE value of 3.96 is a product of the large amount of colors in the image. If you’re looking for a more neutral picture, the sRGB mode’s dE average is only 1.06.
Final words
Overall, the Cooler Master GP27U is a very good monitor. It’s great for the office because the text is clear, the peak brightness is high to cut down on glare, and the ergonomics make it easy to set up. It’s also great for gaming because it has HDMI 2.1 bandwidth for console gaming.
A fast response time and low input lag for a responsive feel, and VRR support to reduce screen tearing. It shows a wide range of colors in both SDR and HDR, which is important if you want to watch content, and it also shows deep blacks thanks to its good Mini LED local dimming.
