Present menus, visitor information, promotional material and IP-delivered programming in 3,840 x 2,160 resolution on a 50-inch commercial LED-backlit LCD display. LG 50PK640S0UB combines webOS 25 with HDMI 2.0, USB 2.0, RF, LAN, Wi-Fi and Bluetooth connectivity, allowing the screen to accept local devices, broadcast signals and network-delivered content. Optical digital audio output and an external-speaker output provide connection paths for separate audio systems. Embedded Content Manager and Group Manager functions support on-screen content administration without requiring every playback task to originate from an external player. Play via URL, failover capability, a time scheduler, NTP-synchronized timer and USB cloning help standardize content behavior across installed displays. The webOS interface also includes a launcher bar, Quick Access, web browser and a pre-loaded YouTube app. Commercial control features include RS-232C, SNMP, Wake-on-LAN, self diagnostics through USB, HTNG-CEC, Simplink HDMI-CEC, IR output and multi-IR-code support. Hotel Mode, installer-menu controls, port blocking, welcome-screen images and IP Channel Manager functions suit guest-facing environments where source access and on-screen behavior need controlled settings. Vertical setup support permits portrait-oriented installations where the content layout requires it.
