If you prioritize casual gaming, the AOC 24G2SPU offers a higher refresh rate for smoother gameplay and has a smaller screen size that's standard for gaming at a closer range. For productivity tasks and media consumption that benefit from higher resolution, the Dell S2721QS with its larger screen and 4K resolution may be more suitable, providing sharper text and clearer images, but with a lower refresh rate that's not ideal for fast-paced games. Neither monitor is well-suited for professional color work or high-end competitive gaming. Choose based on whether gaming performance or image clarity for work and entertainment is your priority.

Scharon Harding | September 2021
"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."
