If cost is a major consideration and you primarily focus on productivity with tasks that benefit from an unusual screen shape, the LG DualUp with its 16:18 aspect ratio might suit you well. However, if you're a serious gamer or a media enthusiast willing to invest in a premium experience, the MSI MAG with its higher contrast, HDR support, and better color performance will serve you better, particularly for HDR gaming and viewing. Keep in mind, the MSI has a higher refresh rate beneficial for competitive gaming but also commands a higher price. Give Feedback
