If you're a competitive gamer looking for high responsiveness with less concern for vibrant colors and contrast, the Dell S2522HG is a budget-friendly choice that delivers high refresh rates and low response times, necessary for fast-paced games. On the other hand, if you're a professional in digital photo editing or a serious HDR gaming and media enthusiast, the Acer X27U with its superior color depth, contrast, and HDR performance will serve you well, albeit at a premium price. It's less suited for productivity due to its lower resolution when compared to its price point. Give Feedback

IGN
Matthew Smith | February 2022
"The Dell S2522HG changes the game. This 24.5-inch 1080p gaming monitor has a 240Hz refresh rate, yet it’s commonly sold for $249.99. That’s just tens of dollars more than an average 1080p 144Hz gaming monitor. The S2522HG cuts a few corners in its pursuit of pricing, but it’s a great choice for competitive gamers on a budget."
