If you engage in high-level competitive gaming and appreciate quick response times with minimal ghosting, the Asus PG34WCDM's superior performance in these areas may justify the higher cost. The Acer Predator X45, however, excels in color accuracy, making it ideal for tasks like digital photo editing and HDR video editing. Both monitors have OLED technology that provides deep blacks and excellent contrast, but if you're concerned with text clarity and image sharpness for productivity tasks, these monitors might not be the best due to their lower pixels per inch. Consider the Acer if your work and play lean more towards color-critical applications; opt for the Asus if your priority is a high-performance gaming experience. Give Feedback
