If a larger screen and higher resolution for detailed productivity tasks or immersive media consumption are important to you, the Dell S2721DGF is a solid choice, despite its higher cost. However, if you prioritize fast-paced competitive gaming and can compromise on screen size and resolution, the ViewSonic XG2431 with its higher refresh rate and response performance might be more appealing, while also saving you some money. Neither monitor is the best fit for HDR gaming or professional color work where higher color accuracy and brightness are needed. Give Feedback

"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."
