If you're a competitive gamer or enjoy high-quality HDR gaming and media, the Asus PG34WCDM with its superior contrast, color depth, and very high refresh rate offers an excellent experience but at a premium price. Conversely, the Dell S2721QS, while less suitable for competitive gaming due to its lower refresh rate and response time, offers very good text quality and image clarity at a more affordable cost, making it a solid choice for productivity and casual gaming. Keep in mind, the Asus's OLED panel provides deeper blacks and vibrant colors, but for tasks like digital photo editing, both are suitable with good color accuracy. If budget is a constraint and competitive gaming isn't a priority, the Dell may suit your needs; however, for top-tier gaming performance and media consumption, the Asus is the standout – if you're willing to invest more.

"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."
