If you're a serious gamer looking for an immersive experience with deep blacks and high contrast, the Corsair 45WQHD240 with its OLED panel and wider color gamut would be an excellent choice, though it comes at a premium price and its text clarity might be lacking for detailed productivity tasks. On the other hand, the Dell S2721DGF offers good color accuracy, better text clarity for productivity, and is still capable for casual to moderate gaming at a midrange price, but it won't match the Corsair's performance in HDR gaming or media consumption. Consider the Corsair for top-tier gaming and media, and the Dell for a balanced mix of productivity and gaming within a more modest budget. 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."
