If you prioritize a top-notch gaming experience with exceptional contrast and color depth, the Asus PG34WCDM (W-OLED) excels, especially for HDR gaming and media with its wider color gamut. Its larger, curved screen and higher resolution also enhance immersive gaming and multitasking for productivity. However, for a tighter budget, the Dell S2522HG (IPS) offers a very good gaming performance at a lower resolution, suitable for casual and competitive gaming due to its lower response time. The Dell is also more practical for day-to-day productivity with sufficient text quality but is not ideal for HDR content and has a less vivid color range for editing tasks. 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."
