If you're looking for a monitor within a more affordable range and still want a premium OLED experience, the Acer X34V could be an excellent choice, especially for casual and competitive gaming due to its high refresh rate and good response time. It's also suitable for media consumption, although it may not be the best for productivity tasks given its smaller screen size and lower resolution compared to the MSI. On the other hand, the MSI MPG 491CQP offers a much wider display and higher resolution, which could be great for productivity and an immersive media experience but comes at a higher cost. If HDR video editing and print photo editing are important to you, the MSI has the edge with better color coverage in those areas. However, you'll pay a premium for these capabilities, and it may not deliver the same level of gaming experience as the Acer due to its response time and refresh rate. Give Feedback
