If you prioritize a high refresh rate and exceptional contrast for immersive gaming experiences, the AOC AG456UCZD with its OLED panel is an ideal choice, but it's a significant investment and not as suitable for text clarity in productivity tasks. On the other hand, the LG DualUp offers good image clarity and is more budget-friendly, excelling in productivity with its unique aspect ratio, although it may fall short in gaming performance due to a lower refresh rate and contrast. If HDR gaming and media consumption are important to you, the AOC will excel, but for digital photo editing and text-heavy work, the LG could be more appropriate. Give Feedback
