If you're focused on digital photo editing and need a monitor with very high image clarity, the LG UltraFine 5K might be the better option, albeit at a premium price. Its glossy coating provides exceptional text quality, making it excellent for productivity tasks as well. However, if budget is a concern and you're looking for a larger, cost-effective monitor with a unique aspect ratio for multitasking, the LG DualUp offers good image clarity at an upper midrange price, but it won't match the UltraFine's superior resolution and it's not as suitable for tasks requiring the highest image detail. Neither are ideal for HDR gaming or competitive gaming due to their poor refresh rates and response times. Give Feedback
