The Dell S2721DGF offers a solid balance for casual gaming and productivity at a more affordable price, with a decent refresh rate and resolution. It is suitable for digital photo editing with good coverage of the sRGB color space. However, for competitive gaming and media consumption, the Nubia RedMagic GM001J steps ahead with its higher resolution, superior HDR performance, and excellent color accuracy across multiple color spaces, making it ideal for both HDR gaming and HDR video editing. The higher price of the Nubia monitor reflects its advanced features, including a better contrast and brightness, which are significant for an immersive gaming and viewing experience. If budget allows and you prioritize high-fidelity visuals and HDR content, the Nubia RedMagic GM001J would be the better choice. Give Feedback

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."
