If you prioritize immersive gaming experiences and photo editing with excellent contrast and color fidelity, the Acer Predator X45 with its OLED panel is a suitable choice, particularly for HDR gaming and media. However, it's more expensive and might not perform as well for fast-paced competitive gaming due to potential ghosting. On the other hand, the BenQ XL2566K offers a superior competitive gaming experience with higher refresh rates and minimal ghosting at a lower price point, but it falls short for HDR content and color-critical work like photo editing due to its TN panel. It also offers lower image clarity compared to the Acer. 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."
