The LG 50PK640S is a 50″ 4K UHD commercial TV designed for 16/7 business signage and commercial display applications. Running LG webOS 25 on an upgraded SoC, the 50PK640S handles content scheduling and playback natively without a separate media player, and supports LG SuperSign CMS for centralised multi-display content management. The larger 50″ format increases viewing distance range compared to the 43″ variant, making it suited to retail floors, food service environments, and corporate spaces where a larger display area is required.
The display delivers 4K UHD resolution at 300nit typical brightness with a 5,000:1 static contrast ratio. The embedded Content and Group Management System enables playlist editing, group scheduling, and display control directly from the unit. Display Power Management (DPM) supports energy-efficient operation by powering the display based on signal detection, reducing consumption during non-operating hours.
Remote fleet management is provided via the optional LG ConnectedCare cloud service. The PK640S series is rated for 16/7 operation — suited to business environments that require reliable commercial-grade performance across standard operating hours but do not need continuous 24/7 uptime.
4K UHD for sharp large-format signage
The 50PK640S delivers 3,840 × 2,160 UHD resolution, rendering promotional graphics, menus, and branded content with sharp detail at the longer viewing distances typical of 50″ commercial installations. The larger format extends the practical viewing distance range compared to 43″ variants.
