If you prioritize exceptional text clarity and pixel density for activities such as digital photo editing, the LG UltraFine with its higher resolution could serve you well despite its higher price. However, for immersive media consumption and HDR gaming, the MSI with its excellent contrast and wider color gamut will deliver superior visuals. Gamers, especially those into competitive gaming, may prefer the MSI for its faster refresh rate and variable refresh rate support. The curved screen of the MSI can also offer a more engaging experience for entertainment and gaming but may be less ideal for strict productivity tasks compared to the LG's conventional flat display.
