If you're passionate about competitive gaming and can invest in a higher-end experience, the AOC AG456UCZD with its OLED panel will offer deeper blacks and superior contrast, which enhances the gaming atmosphere and overall visual quality. However, its image clarity and text quality aren't as strong, which could be a drawback for productivity tasks. On the other hand, the Dell S2522HG is more budget-friendly and still provides a very good gaming experience, with its strengths being better suited for productivity due to clearer text and image. For media consumption, the AOC's better contrast and color depth would be beneficial, but the Dell falls short in this aspect. Decide based on whether competitive gaming performance and immersive media experience outweigh the need for clearer text and greater affordability. 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."
