If competitive gaming is your priority and you’re looking to save money, the BenQ XL2566K offers a very high refresh rate and low response time, excelling in fast-paced games but with lower screen resolution and size. However, for a premium, the CoolerMaster GP27U boasts a sharper image with a higher resolution and bigger screen, alongside superior color accuracy and brightness, making it better for HDR gaming, media consumption, and photo editing. Keep in mind that the higher resolution might demand more from your gaming hardware. Give Feedback

"It’s not for everyone in the same way that a top fuel dragster isn’t everyone’s perfect daily driver. The BenQ Zowie XL2566K succeeds in delivering the fastest, sharpest and smoothest display for pro FPS players and that’s all it wanted to do. Its other limitations and premium price tag mean it’s a bespoke tool for a niche market, rather than another general gaming monitor for those who like playing games."

"The Cooler Master Tempest GP27U leaves little to complain about. It delivers a stunning picture with high contrast, brightness, and vivid color. Professional-grade video processing means a superlative gaming experience. And it’s a little less expensive than the competition."
