If you prioritize a larger screen and ultrawide aspect ratio for an immersive experience in productivity and general media consumption, and are willing to pay more, the LG 34WQ75C could be a suitable choice. On the other hand, if you prefer a monitor that is more budget-friendly and offers a higher resolution which is better for detailed work and sharper text, the Dell S2721QS would be a better fit. Neither of these monitors are ideal for gaming due to their poor refresh rates and response times, nor for HDR content due to limited peak brightness and color gamut. However, the Dell offers a slightly better experience for digital photo editing with better color accuracy. 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."
