LG UM670H 55"

Built for centralized management, the 55-inch 4K LCD integrates Pro:Centric Direct CMS and Pro:Idiom DRM for streamlined content delivery and secure in-room entertainment. Its webOS smart platform and three HDMI inputs, including one with ARC, provide flexible connectivity for guest devices. This display is best for hotel operators needing a reliable, remotely managed hospitality TV rather than consumers seeking high-refresh gaming or cinematic picture quality.
