If you prioritize high resolution for detailed images and more screen space for multitasking, the Dell S2721QS with its sharper display would be a better fit. It's also good for digital photo editing due to its color accuracy. On the other hand, if you're focused on gaming, especially fast-paced competitive games, consider the Innocn 27G1S with its higher refresh rate and very low response time, which result in smoother gameplay and less motion blur. However, the Innocn's lower resolution means less detail compared to the Dell. Neither of these monitors is ideal for HDR gaming or professional HDR video editing. 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."

Allen Ngo | June 2023
"The monitor is a sweet spot for gamers who want something faster than 165 Hz while keeping the benefits of fast response times and relative affordability. The VA panel is now more competitive against many IPS options."
