If budget is a concern and you're looking for a solid all-around monitor for casual gaming and digital photo editing, the LG 27GP83B could serve you well. However, the MSI MAG 321UPX is a higher-end option that excels in HDR gaming, media consumption, competitive gaming, and HDR video editing, with superior contrast and color performance. If you're willing to invest more for a monitor that delivers exceptional image quality and are interested in a larger screen with higher resolution, the MSI could be worth the additional cost. Keep in mind, for text clarity and preventing ghosting, the LG is the better option. Give Feedback
