Description
The LG 55UN640S is a 55-inch 4K UHD commercial TV designed for retail, corporate and hospitality signage where a professional, always-on display is required. The 3840 x 2160 UHD panel delivers four times the detail of Full HD, with HDR10 Pro and HLG support for punchy, realistic colour and a slim profile that saves installation space compared with earlier LG commercial models. An embedded Content and Group Management System lets a single operator edit and play content, schedule playlists across groups of screens, and control signage using a remote control, mouse or mobile phone, with no separate PC or CMS software needed. The set also runs LG's webOS 22 platform with an upgraded SoC and web engine, and is compatible with SuperSign Control+ for larger fleet deployments. For professional installs, the UN640S supports Crestron Connected for integration with third-party AV control systems, and includes Beacon and Bluetooth Low Energy so retailers can push proximity-based coupons and information to nearby shoppers. Display Power Management (DPM) can be configured to power the panel only when a signal is present, reducing running costs in unattended installations.
