Choosing between the LG 34WQ73A and MSI MPG 491CQP depends on your priorities and budget. If you are price-sensitive and your usage leans towards productivity tasks and casual gaming, the LG with its wide screen and good text quality could serve you well. But if you're willing to invest in a premium experience, especially for HDR gaming and media with rich color and contrast, the MSI's superior image quality and color accuracy will stand out. However, the MSI monitor's higher price might not be justified if high refresh rates for competitive gaming are not a priority for you. Give Feedback
