If competitive gaming is a priority and you want to save money, the Acer X27U offers a higher refresh rate and better response times. However, if you’re looking for higher screen resolution for tasks like digital photo editing or you prioritize image clarity over gaming performance, the LG 27EP950 might be worth the extra cost, even though it has a lower refresh rate and is not designed for HDR gaming. Neither of these OLED monitors is ideal for productivity given the risk of static image retention, and both offer similar color accuracy for media consumption. Give Feedback
