If gaming performance is a top priority and you're interested in a larger screen size with higher refresh rate capabilities, the Acer XB323U-GX might be the better choice despite its higher price. However, if you're looking for a balance between quality and affordability for both gaming and productivity, with great text clarity and image quality, the Dell S2721DGF provides a robust option at a more midrange price. Neither monitor is ideal for HDR gaming or media consumption due to limited peak brightness, but both are suitable for digital photo editing with good color gamuts. Give Feedback

Tom's Hardware
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."
