If image clarity and high resolution for productivity are priorities, and you don't mind a high price, the LG UltraFine 5K may be more suitable. However, if you prefer an immersive experience with deeper blacks for media and HDR gaming, the MSI MEG with its QD-OLED panel offers superior contrast and is less expensive. The MSI is also better for competitive gaming due to a higher refresh rate. For print photo editing, the MSI’s color accuracy is advantageous. The LG stands out for tasks involving text clarity due to its higher resolution. Give Feedback
