If high-end gaming with deeper blacks and more vibrant colors is paramount, the Acer X27U with its OLED technology is a superior choice. Its high refresh rate and response time are perfect for competitive gamers, but limited brightness might affect daylight usage. Conversely, if budget is a concern and you're engaged in mixed usage like casual gaming, productivity, and everyday media, the Dell S2722DGM offers good performance with a solid build quality. Keep in mind, though, it won't match the Acer's performance in high-speed gaming or color accuracy for tasks like photo editing. Give Feedback

Tom's Hardware
Christian Eberle | February 2022
"Though it leaves out HDR and extended color, the Dell S2722DGM delivers superb gaming performance for less than $300. With Adaptive-Sync, 165 Hz, a solid overdrive and usable blur reduction, it rocks full-motion gaming without breaking the bank."
