If you prioritize high resolution for detailed work or watching high-quality media, the Dell U2723QE with its larger screen and higher resolution could be a better fit. It also has a slightly better contrast, which is good for photo editing. However, the LG DualUp's unique aspect ratio might appeal to you if you're looking for a monitor that can efficiently display multiple applications or documents at once, enhancing productivity. Neither monitor is ideal for HDR gaming or media consumption, but the Dell's higher peak brightness may offer a slightly better experience for standard dynamic range content. If price is a concern, the Dell U2723QE's somewhat lower cost could also be a deciding factor. Both monitors offer an array of USB ports, though the LG has an extra HDMI port. Neither is particularly suited for competitive gaming due to their lower refresh rates and response times, but casual gamers could find either satisfactory. Give Feedback
