If you prioritize competitive gaming with fast response times and high refresh rates, the Acer X27U (W-OLED) offers excellent performance. However, for productivity and media consumption with higher screen resolution, the Dell S3221QS (VA) is a better choice with its larger screen and crisper image clarity at a lower price. The Acer's OLED panel excels in color depth and contrast suitable for HDR gaming and media, whereas the Dell provides a solid all-around experience but isn't the best fit for HDR content. Consider your main use and budget when deciding as the premium price of the Acer may not be worth it if your focus is productivity or casual media viewing. Give Feedback
