If you're serious about competitive gaming and want the best response times and very smooth gameplay, the BenQ XL2566K with a TN panel excels in these areas, albeit at a higher price. But, if you prefer an immersive experience with better color depth and wider resolution for casual gaming, productivity, and media consumption, the Dell S3422DWG offers a larger, ultrawide screen with better color performance and is more budget-friendly. Neither is ideal for professional photo or video editing, but for general use, consider how these aspects align with your priorities. Give Feedback

"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."

"The Dell S3422DWG is, overall, a great monitor that delivers on most of its promises, providing a sharp ultrawide experience with smooth motion. It is, however, not as great of a value proposition, costing a bit too much compared to similar competitors."
