If you're a serious gamer looking for top performance with deep blacks and vibrant colors, the Acer X34V offers superior gaming capabilities, including a higher refresh rate ideal for smooth gameplay and a wide color gamut for a more immersive experience. However, it's more expensive and may not excel in productivity due to its ultrawide format. The Dell S3221QS, being less expensive, provides a sharper image due to its higher resolution and is better suited for productivity tasks with its 16:9 aspect ratio but it falls short in gaming performance and peak brightness compared to the Acer. For media consumption, the Dell is good but Acer's OLED technology will give you better contrast and HDR experience. Give Feedback
