If competitive gaming is your top priority and you value high refresh rates for fast-paced games, the BenQ XL2566K with its higher refresh capabilities could be the better choice, despite its higher price and lower resolution. However, if you're looking for a monitor that offers a sharper image for productivity tasks, better color accuracy for photo editing, and superior clarity for media consumption, the Dell S2721QS with its 4K resolution may be more suitable, while also being more affordable. Keep in mind that the BenQ's TN panel may not have as good viewing angles and color reproduction as the Dell's IPS panel. Give Feedback

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."

"The Dell S2721QS 4K monitor brings IPS-level colors and some handy features, like a versatile stand with height adjustments and picture-in-picture for connecting dual systems. But don’t get it for HDR."
