If you're primarily focused on casual gaming, productivity, or digital photo editing on a budget, the Dell S2721QS with its high screen resolution and decent color accuracy is a strong choice, especially given its lower cost. However, if you're a serious gamer or want an immersive media consumption experience and are willing to invest in a premium product, the LG 45GR95QE-B offers superior contrast, response time, and a wide color gamut which greatly enhances HDR gaming and video watching, with a higher refresh rate beneficial for competitive gaming, but it may not be as suitable for tasks requiring precise text clarity or image detail due to its lower pixels per inch.

"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."
