If you prioritize high quality visuals and are interested in vibrant colors for HDR gaming and media, the AOC AG276QZD with its OLED panel is the better choice despite its higher price. However, if you are focused on competitive gaming and need the highest refresh rates with minimal ghosting, the BenQ XL2566K will serve you better at a lower cost, though it falls short in color performance and resolution for everyday productivity and media enjoyment. The AOC also excels in tasks involving photo editing due to its color accuracy, while the BenQ does not support these activities well. 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."
