Our Verdict
Cooler Master Tempest GP27U
Acer Nitro XV275K P3biipruzx
The Acer Nitro XV275K P3biipruzx and the Cooler Master Tempest GP27U are similar 27-inch, 4k monitors with Mini LED backlighting. However, there are a few differences between them The Acer has much better accuracy before calibration and slightly better reflection handling. The Cooler Master has better motion handling and lower input lag for a more responsive feel. The Cooler Master even has a KVM switch, ideal for multitasking, which the Acer doesn't have.
