If competitive gaming is your priority, and you want high responsiveness with lower input lag, the BenQ XL2566K is an excellent choice, especially if you want to save money. However, for tasks that require high color accuracy and better viewing angles, like digital photo editing or enjoying high-resolution movies, you'll be better served by the ViewSonic XG321UG despite its higher cost. The ViewSonic's larger screen and greater clarity make it more suitable for productivity and media consumption. Keep in mind, the BenQ's lower screen resolution is less ideal for detailed work or immersive media experiences. 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."
