If you're on a budget and mainly use your monitor for productivity tasks and digital photo editing, the Dell S2721QS offers good text clarity and image quality at a budget price, making it a strong choice. On the other hand, if you're willing to invest in premium features for a better experience in media consumption and high-quality print photo editing, the ViewSonic XG321UG, with its better contrast and color depth, would be a better option, though it comes at a typically much higher price. Keep in mind, neither of these monitors is ideally suited for HDR gaming. 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."
