If you prioritize gaming and media consumption on a budget, the Dell S2721QS provides a larger, 4K resolution for crisp visuals, though not suitable for HDR content. It's also a better choice for digital photo editing. On the other hand, the LG DualUp stands out in productivity with its unique aspect ratio that offers more vertical space, which can benefit tasks like coding or writing. However, the LG monitor is more expensive and doesn't add much value for gaming or watching movies due to its unconventional screen layout and unknown HDR capability. Choose the Dell for a budget-friendly, all-around performance, and the LG for specialized productivity with a higher cost. 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."
