If you prioritize competitive gaming, the Acer X27U with its excellent refresh rate and fast response time provides smoother gameplay. However, for immersive media consumption and HDR gaming, the MSI MPG 491CQP's larger screen and superior color gamut will enhance your experience, but it may cost more. For productivity tasks, the ultra-wide aspect ratio of the MSI can display more content, which is useful for multitasking, but if you need a monitor with higher resolution, the Acer won't serve this aspect as well. Make your choice based on whether your priority is a better gaming experience or enhanced media and work capabilities. Give Feedback
