The recently released TEMPEST GP27U from Cooler Master is a 27-inch Mini LED monitor with a 4K resolution and a refresh rate of 160Hz. This monitor delivers an impressive HDR experience, and its price of $800 is a great deal.

There have been numerous issues reported by the community following the launch of the monitor. This raises concerns that the launch may have been rushed, as the company was aware of these problems but released the product without resolving them.

The company has made ongoing efforts to fix the known issues and has released several updates from Cooler Master to address these problems. In this article, we will provide an overview of the issues that have been resolved and the actions taken by the company to resolve them.

A Quick Review of the Tempest GP27U

For under $1000, this monitor provides an impressive HDR experience with its 27-inch 4K 160Hz IPS panel from AU Optronix, featuring a mini LED backlight. It is capable of reaching up to 1400 nits of peak brightness.

Adaptive sync 

One of the significant problems that users have encountered with this display is that, upon activation, the screen is limited to 144Hz instead of the advertised 160Hz. The functionality of the HDR and local dimming with adaptive sync is also impaired. These issues were particularly evident when using mid-range GPUs such as the 6900 XT or 3090. To resolve these problems, Cooler Master has released two firmware updates to date.

Cooler Master resolves Tempest GP27U problems with latest firmware update

It is possible to enable both adaptive sync and HDR simultaneously, allowing your monitor to reach a refresh rate of 160Hz. In addition, additional color adjustments have been added to all picture modes. These updates, in addition to minor fixes introduced in the first update, are now available.

It is heartening to see that some of the issues, which were originally thought to be minor by the public, have been addressed. VRR and 160Hz now work flawlessly together. These fixes, combined with the TEMPEST GP27U’s exceptional price to performance ratio, make it a top-notch gaming monitor.

Releasing firmware updates to fix issues is a common practice among monitor manufacturers, and these updates may take longer than expected. Although Cooler Master may have fewer resources in the monitor department, they have managed the situation more effectively than Samsung did with the NeoG9s.
