If you prioritize a unique aspect ratio for multitasking and a more affordable option, the LG DualUp 28MQ780 could suit your productivity needs. In contrast, the MSI MPG 491CQP offers superior contrast and color performance, ideal for immersive HDR gaming and media consumption, but at a higher cost. Consider the MSI for a wide, cinematic display ideal for graphic design or video editing due to its exceptional color accuracy. However, the LG's higher resolution and aspect ratio might be preferable for text-heavy tasks and managing multiple windows, but it won't match the MSI's performance in visual quality. Give Feedback
