If you prioritize a higher resolution for tasks like digital photo editing, the Dell S2721QS offers a crisp 4K screen at a more affordable price, making it suitable for productivity and casual gaming. However, for a premium gaming and media experience, the Samsung Odyssey OLED G8 has exceptional contrast and color with wider viewing angles, and better performance in fast-paced games due to its higher refresh rate and response time. The Samsung is more expensive, but it excels in HDR gaming and movie watching, with its deep blacks and vibrant colors. Choose the Dell for budget-friendly productivity and casual use, or the Samsung for top-tier gaming and media enjoyment. 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."
