If you're looking for a high-end experience with sharp image quality and superior color performance for tasks like HDR gaming, photo editing, and watching media, the CoolerMaster GP27U would serve you well, as it also has features like a higher refresh rate for smooth gaming. However, if your budget is tight and your usage includes more everyday tasks like casual gaming, web browsing, and office work, the Dell S2721DS provides satisfactory performance without the premium cost. Keep in mind, though, that the Dell monitor won't be as impressive for high dynamic range content or for professional color work. Give Feedback
