If you prioritize top-notch gaming performance with vibrant colors, deep blacks, and high refresh rates, investing in the Asus PG32UCDM (QD-OLED) would be beneficial, especially useful for HDR gaming and media. However, for everyday tasks like web browsing and office work, the Dell S2721DS (IPS), with its lower price, is a cost-effective choice, offering good image clarity but it won't match the Asus regarding color brilliance or gaming prowess. Choose the Asus for a premium experience if budget allows, or the Dell for day-to-day use where price is a primary concern. Give Feedback
