If you prioritize competitive gaming and are on a tighter budget, the BenQ XL2566K with its high refresh rate and low response time is designed for fast-paced games. However, the Cooler Master GZ2711 with OLED technology offers better color depth, contrast, and higher resolution which is great for general media consumption and photo editing. The BenQ's resolution and color reproduction aren't as strong, making it less ideal for tasks that require precise color accuracy. On the other hand, the Cooler Master is more costly, but its superior display attributes make it versatile for both gaming and creative work. 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."
