If you prioritize competitive gaming and media consumption with a wide, immersive display, the AOC PD49 (QD-OLED) will offer a superior experience due to its high refresh rate and excellent contrast. On the other hand, if your focus is on productivity tasks that benefit from extremely sharp text and image clarity, such as digital photo editing, the LG UltraFine 5K with its higher resolution might be a better fit. The OLED panel of the AOC provides deep blacks and vibrant colors, which is great for HDR gaming and video editing, but the LG's IPS panel offers more accurate colors for tasks like print photo editing. Keep in mind, the AOC offers a vast screen real estate that can be beneficial for multitasking, but the LG offers a glossy screen that can make colors pop, although it may reflect more light.
