If you're a competitive gamer looking for high refresh rates and quick response times at a lower cost, the BenQ XL2566K might be the right fit, though it falls short in color accuracy and viewing angles. On the other hand, the KTC G27P6 offers superior color performance and contrast with its OLED panel, making it excellent for HDR gaming and media consumption, as well as digital photo editing, but you'll invest more and you may not need its capabilities if competitive gaming is your main focus. Keep in mind, the higher resolution of the KTC also means sharper images but may demand more from your gaming setup. Give Feedback

Tech Radar
Nick Ross | August 2023
"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."
