If you prioritize high-end gaming with deep blacks and vivid colors, the Asus PG32UCDM (QD-OLED) is a superior choice, particularly beneficial for fast-paced games thanks to its excellent motion handling and variable refresh rate support. It's also great for HDR gaming and media consumption. However, if your focus is more on general productivity and cost-effectiveness, the Dell S2721QS (IPS) offers good image clarity and color accuracy for its price, making it a solid choice for everyday use and casual gaming, despite its lower refresh rate and less impressive contrast. The decision should be based on whether the premium gaming features of the Asus are worth the higher price tag to you. Give Feedback

"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."
