If you're a competitive gamer looking for smooth gameplay, the Acer's higher refresh rate and responsive performance would serve you well, but it comes at a premium price. The Dell, offering better image detail due to its higher resolution at a more affordable cost, is more suited for general productivity and content consumption. Both monitors have their strengths, so if gaming is your focus, the Acer could justify its higher cost, whereas the Dell might be the better all-rounder if budget and sharp images are your priority. Neither is ideal for HDR gaming or professional photo editing, where color performance is critical. Give Feedback

Scharon Harding | September 2021
"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."
