If you prioritize a larger screen and superior color performance for activities like HDR video editing and photo editing, the MSI MAG 321UPX (QD-OLED) would be an excellent option, and it also excels in media consumption. It's also a strong candidate for competitive gaming due to a higher refresh rate and variable refresh rate support. Meanwhile, the LG 27EQ850 (W-OLED) offers an exceptional contrast ratio and is well-suited for HDR gaming and media consumption but falls short in competitive gaming due to the lower refresh rate. Its smaller screen could be a drawback for some users. If budget is a significant concern, the MSI offers more features and better performance at a lower cost, making it a more valuable option overall. Give Feedback
