If you prioritize high-quality HDR content or work with print photo editing, the LG 39GS95QE with its superior contrast and color depth would suit you better, although it comes at a premium price. On the other hand, the Dell S2721DGF offers a good balance for casual gaming and digital photo editing at a more accessible price point. The Dell is also better suited for productivity due to higher text quality and image clarity. However, for competitive gaming, the LG’s higher refresh rate and response time give it an edge, albeit its overall gaming performance for casual gamers may not justify the higher cost compared to the Dell.

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."
