If high-quality visual experiences in gaming and media are a priority and the budget allows, the Acer X27U with its OLED panel offers deeper blacks and vibrant colors, making it superior for HDR gaming and media consumption. It also has higher brightness levels, which contribute to better picture quality in various lighting conditions. However, if cost is a significant concern and gaming is more casual, the Dell S3222DGM is much more wallet-friendly and still provides a good experience with its VA panel, which generally offers better contrast than typical LCDs but may not match the color performance or viewing angles of OLEDs. The Acer's very high refresh rate is great for competitive gaming, but the Dell's refresh rate is sufficient for most players. For productivity tasks or if image clarity in brightly-lit environments is vital, neither monitor excels, so your choice here should hinge on the preferred gaming and media experience versus price sensitivity.

Christian Eberle | February 2022
"Aside from its omission of HDR, the Dell S3222DGM has no flaws of consequence. For a surprisingly low price, it delivers premium quality gaming performance with 165 Hz and Adaptive-Sync through a high-contrast curved VA panel with a wide and accurate color gamut."
