If you're focused on competitive gaming, the Dell S2721DGF offers features such as a higher refresh rate for smoother gameplay at a lower price. However, if you're into digital photo editing or print photo editing, the Dell's color accuracy makes it a strong choice and maintains good image clarity. On the other hand, the LG 34WQ75C's larger, ultrawide screen enhances productivity and immersion in media, at a higher cost. Keep in mind, the LG might not be as suitable for competitive gaming due to its lower refresh rate. Both monitors have their strengths, so your decision should be based on whether you value gaming performance or a broader, more expansive display for work and entertainment. 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."
