If your primary focus is on competitive gaming, the AOC with its excellent refresh rate and response time will deliver smoother gameplay. However, the LG UltraFine excels in image clarity and text quality, making it great for productivity tasks and digital photo editing. The AOC's OLED panel provides deeper blacks and potentially better contrast for HDR gaming and media, but this comes at a higher price. If budget is a concern and your needs lean toward professional work involving high resolution and color accuracy, the LG offers impressive features at a lower cost. Give Feedback
