If you prioritize a higher-quality gaming experience with rich colors, quick response times, and smoother gameplay due to its higher refresh rate, the Corsair 45WQHD240 is a strong choice, especially if you're into HDR gaming and media consumption. However, its price is significantly higher, and it's less suited for productivity tasks due to its poor text quality and image clarity. On the other hand, the Dell S2721DS, while more budget-friendly and better for everyday productivity with good text quality and image clarity, lacks performance in gaming and isn't suitable for HDR content, with a lower refresh rate and color performance that's less vibrant.
