If your primary interest is competitive gaming and you're looking to save money, the BenQ XL2566K with its higher refresh rate and quick response time could serve you well, but its smaller size, lower resolution, and poorer color performance may detract from productivity and media viewing experiences. Conversely, if you value a vast screen space, superior color accuracy, and exceptional contrast for a more immersive experience in HDR gaming and media consumption, and are willing to invest more, the Gigabyte CO49DQ is a strong option, though it may not be as optimal for competitive gaming due to its lower refresh rate and response times.

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."
