If you prioritize high-resolution content and professional-grade color accuracy for tasks like HDR video editing and print photo editing, the Innocn 27M2U with its superior image clarity, high static contrast, and excellent color volume is a strong contender despite its higher price. On the other hand, the Dell S2721DGF offers good performance for causal gaming and productivity at a lower cost, with a higher refresh rate which is beneficial for competitive gaming. However, its color performance and HDR capabilities aren't on par with Innocn's, making it less ideal for color-critical work and HDR gaming or media consumption. Choose the Innocn if you require top-notch visual fidelity and work with HDR content, or opt for Dell if you're seeking a more affordable option with a balance of gaming and everyday productivity performance.

Christian Eberle | January 2021
"The Dell S2721DGF checks all the boxes for an upper-mid priced display that can take on the best gaming monitors, and you might even be able to find it for under $500 (it's $450-$500 as of writing). The monitor's 1440p, runs at 165 Hz without overclock, has AMD FreeSync Premium Pro and G-Sync Compatibility, covers a large portion of the DCI-P3 color gamut and includes a lighting effect on the back."

Mark Sparrow | November 2022
"The Innocn 27MU2 screen isn’t built to Apple standards, but it’s robust enough for desktop use and surprisingly lightweight, considering its image quality. The stand is rock steady and adjustable, plus the screen can be wall mounted. There are plenty of input options plus the ability to display two sources on screen at the same time."
