The LG 65PK640S is a 65″ 4K UHD commercial TV designed for 16/7 business signage and large-format commercial display applications. Running LG webOS 25 on an upgraded SoC, the 65PK640S handles content scheduling and playback natively without a separate media player and supports LG SuperSign CMS for centralised multi-display content management. The 65″ format is suited to high-visibility open-plan retail, corporate lobby, restaurant, and conference room environments where impact at distance is required.
The display delivers 4K UHD resolution at 260nit typical brightness with a 1,200:1 static contrast ratio. The embedded Content and Group Management System enables playlist editing, group scheduling, and display control directly from the unit without external CMS software. Display Power Management (DPM) reduces energy consumption by automatically powering the display based on signal detection 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 requiring reliable commercial-grade performance across standard operating hours without the cost premium of a full 24/7-rated panel.
4K UHD for high-impact 65″ signage
The 65PK640S delivers 3,840 × 2,160 UHD resolution, providing the visual presence required for open-plan retail floors, corporate lobbies, and conference environments at extended viewing distances. The 65″ format delivers significantly more impact than 55″ and smaller variants in large-format applications.

Slim profile for large-format installs

Display Power Management reduces energy use
DPM powers the display based on signal detection, automatically reducing energy consumption during non-operating hours. Relevant for large-format installations connected to a scheduled signal source or timer-controlled AV system.
LG ConnectedCare for remote monitoring
The optional LG ConnectedCare cloud service remotely monitors display status and enables fault diagnosis without on-site attendance. Suited to multi-site operators managing distributed large-format display fleets.
