If you're a dedicated gamer, especially in competitive settings, the AOC AG276QZD with its high refresh rate and quick response time will offer a fluid and responsive gaming experience. On the other hand, if you prioritize a larger screen for productivity tasks and media consumption, along with a higher resolution for crisper images, you may find the Dell S3221QS more suitable despite its slower refresh rate which is less ideal for fast-paced gaming. For HDR gaming and media, both monitors are capable, but the AOC's OLED panel will deliver deeper blacks and more vibrant colors. If budget is a concern, the Dell offers significant savings while still providing a quality experience for everyday tasks and casual gaming. Give Feedback

"The Dell S3221QS offers a 4K, 32-inch panel that’s great for streaming videos and casual gaming, with an effective, gentle curve. But color accuracy and HDR performance leave much room for improvement."
