If you prioritize a premium gaming experience with high contrast, impressive color accuracy, and are interested in HDR gaming and media consumption, consider the Asus PG27AQDM, despite its higher price tag. However, it doesn't perform as well for productivity tasks. On the other hand, if you're looking for a more affordable monitor that's still good for competitive gaming with a faster response time and less ghosting, but less suitable for high-fidelity color work or HDR content, the Dell S2522HG may suit your needs better. Keep in mind the Dell has a lower resolution and might not be as sharp for detailed work. Give Feedback

"It’s hard to find any fault with the Asus ROG Swift PG27AQDM. Yes it’s expensive, but it’s incredibly good. With a stunning image and next-level video performance, it’s one of the very best gaming monitors I’ve ever reviewed."

"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."
