Introduction

We didn’t have to wait long for Mini-LED technology to make its way from TVs to monitors, and gaming-oriented PC brands have already begun implementing it in their high-end products. In 2022, Cooler Master introduced two Mini-LED monitors: the Tempest GP27U and the Tempest GP27Q. Both are 27-inch Quantum Dot displays with high refresh rate IPS panels, but the main difference is their native resolution. The Tempest GP27U has a 4K resolution, while the GP27Q, which we will review here, has a 2560×1440 resolution. This makes the GP27Q a more appealing option for those who want the highest possible framerate or don’t have a top-of-the-line gaming system, as 2560×1440 requires significantly less GPU power than 4K.

Before moving on, it’s important to note that Mini-LED isn’t a display panel technology. Mini-LEDs are tiny LEDs, typically a few millimeters in size, and are used in arrays to provide backlighting for LCDs. One of the main advantages of Mini-LED technology is that it can produce higher contrast ratios and more vibrant colors compared to traditional LCDs. This is because the smaller size of the Mini-LEDs allows for more precise control over the intensity of the backlight, which is split into 576 local dimming zones in the case of the Cooler Master Tempest GP27Q. Opting for a Mini-LED monitor has many potential advantages, such as a very high contrast ratio and high peak brightness. As a direct result, such displays can provide a true HDR gaming experience, unlike “regular” PC monitors lacking local dimming technology.

Having a Mini-LED backlighting system is one of several strong selling points of the Cooler Master Tempest GP27Q; the monitor is stacked in pretty much every other area that matters to gamers, and even has much to offer to professionals (KVM switch, 90 W Power Delivery USB-C port), including those that are doing color-critical work. With a surprisingly reasonable price tag of $500, it is also one of the most affordable entries into the world of proper HDR on a PC, making it that much more interesting.
