If gaming, particularly with fast-paced titles, is your priority and you seek a smoother experience, go for the Dell S2721DGF due to its higher refresh rate and better response times, but note that you'll compromise on color accuracy important for tasks like photo editing. Conversely, if your work involves design or photo editing where color precision is crucial, the LG DualUp with its superior color gamut coverage might be worth the extra investment. The LG's unique 16:18 aspect ratio offers a vertical workspace that can boost productivity by displaying more content, but this could be less ideal for traditional gaming and media viewing experiences. The Dell's 16:9 aspect ratio, on the other hand, is standard for most media and games. Keep in mind, the Dell offers some HDR functionality while with the LG, HDR performance is not specified.

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."
