If high-resolution and exceptional text clarity are critical for your productivity tasks, the LG UltraFine 5K could be a solid investment, but keep in mind that its refresh rate isn't suited for competitive gaming. On the other hand, the MSI MPG 271QRX, with its QD-OLED panel, offers infinite contrast and vibrant colors that excel in HDR gaming and media consumption, plus it has a high refresh rate for competitive gaming. However, the lower resolution might be less ideal for tasks that benefit from more screen real estate. The MSI monitor offers great value if you prioritize gaming and media over ultra-high resolution for productivity. Give Feedback
