The Dell S2721DGF offers a good balance for casual gaming and productivity at an upper midrange price, with a higher refresh rate beneficial for smooth gameplay, but it is not suitable for HDR gaming and media consumption. The ViewSonic XG321UG, on the other hand, is at a premium price and better suited for tasks requiring high color accuracy, such as print photo editing, due to its superior HDR capabilities and color gamut, though it has a lower refresh rate making it less ideal for competitive gaming. If budget is less of a concern and color-sensitive work is a priority, consider the ViewSonic; if you're looking for a more cost-effective option that favors gaming and everyday tasks, the Dell might be the right choice.

"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."
