If you prioritize a larger, ultrawide screen for immersive gaming and productivity with deep blacks and excellent contrast, the Acer Predator X45 may be worth the extra investment. However, if you're focusing on competitive gaming and want a monitor with high clarity and less ghosting, the Asus PG27AQDM is a more affordable option that still offers the benefits of OLED technology. Keep in mind, the Asus has a smaller screen and is better suited for single-tasking. Neither is ideal for HDR video editing or print photo editing due to their color volume limitations. Give Feedback
