43-inch 4K UHD commercial TV signage display
LG 43PK640S0LB
The LG 43PK640S0LB is a 43-inch 4K UHD commercial TV signage display built for professional deployments in retail, corporate lobbies, hospitality, and quick-service restaurants. Powered by the LG webOS 25 smart signage platform with an upgraded Quad-core SoC, it handles content scheduling, group management and playback entirely without a separate media player or PC. HDR10 Pro and HLG support deliver rich, accurate colour and contrast, while the slim Direct LED panel keeps installation straightforward in space-constrained settings. Full LAN, Wi-Fi, RS-232C and Bluetooth connectivity, combined with optional LG SuperSign CMS and LG ConnectedCare remote monitoring, make it an easy fit into both new and existing signage infrastructures.

4K UHD with HDR10 Pro and HLG
The 43PK640S0LB delivers 3,840 × 2,160 Ultra HD resolution — four times the pixel density of Full HD — combined with HDR10 Pro and Hybrid Log-Gamma (HLG) high dynamic range. In practice this means brighter highlights, deeper blacks and more accurate colour reproduction across all types of content, from promotional video to static graphics. For hospitality or retail environments where on-screen quality directly influences the customer's perception of a brand, the step up from FHD is immediately visible and persuasive. Both HDR standards are supported simultaneously, so the display works with virtually any content source without manual switching or format restrictions.

webOS 25 Built-In — Standalone Signage
The upgraded webOS 25 platform runs directly on the display's Quad-core SoC (K25Lp), eliminating the need for an external media player. This reduces rack space, cabling, and potential points of failure — all of which translate into lower installation cost and simpler long-term support. The platform supports web-based apps, a built-in web browser, YouTube playback, screen sharing via Miracast, and IP streaming (Global IPTV). For deployments ranging from a single screen to a multi-site network, having the player built into every screen makes scaling the installation straightforward without additional hardware investment at each location.

Embedded Content and Group Management
Without any additional software licence or PC, the 43PK640S0LB allows an operator to create playlists, set time schedules, and push content updates to groups of screens directly from a remote control, mouse, or mobile phone. The embedded Group Manager uses a Master-and-Group hierarchy, so a single display can coordinate content across multiple units on the same network. For smaller installations that do not justify the cost of a full CMS subscription, this built-in functionality covers most day-to-day signage needs. For larger networks, it acts as a foundation that integrates seamlessly with LG SuperSign CMS (sold separately) when more advanced scheduling or analytics are required.

Failover for Uninterrupted Display
The PK640S series supports automatic Failover, which switches to a backup content source if the primary input signal is lost. In retail or hospitality settings where blank screens are a visible problem — and where IT staff may not be immediately on-site — this feature keeps content running without manual intervention. Combined with Play via URL and NTP time sync, the display can self-recover from minor network interruptions and stay in sync with the intended schedule. This resilience is particularly valuable for unmanned or remotely managed deployments.

LG ConnectedCare Remote Monitoring
The 43PK640S0LB is compatible with LG ConnectedCare, an optional cloud-based remote management service that provides real-time status monitoring, fault diagnostics, and remote control of deployed screens. For organisations managing multiple installations across different locations, this service reduces the need for on-site visits for routine checks and minor troubleshooting. Fault alerts can be acted on proactively before they become visible problems for end customers. ConnectedCare is purchased separately and its availability varies by region — local LG representatives can advise on licensing.

Slim Design for Space-Constrained Installs
At just 58.3 mm deep without the stand, the 43PK640S0LB has a profile that sits close to the wall and causes minimal visual intrusion. The slim chassis also simplifies VESA mounting (200 × 300 mm) in tight spaces such as grocery store aisles, hotel room walls, or reception desk surrounds. Weight is kept to 6.1 kg without the stand, making single-person installation feasible in most situations. The clean black bezel (6.7 mm on three sides when off) ensures the screen reads as a display surface rather than a bulky appliance.

Comprehensive Connectivity and Control
The display provides 2 × HDMI 2.0 inputs (with ARC on HDMI 2), 1 × USB 2.0, RS-232C (phone jack), optical digital audio out, a 3.5 mm external speaker output, RJ45 LAN, RF antenna input, and a CI slot — covering practically every integration scenario from simple HDMI playback to full RS-232C serial control. Wi-Fi 802.11ac and Bluetooth add wireless flexibility, including Miracast screen sharing and Bluetooth audio. SNMP, WOL (Wake-on-LAN), and Crestron compatibility are also supported, meaning the display integrates cleanly into professional AV control systems without additional adaptors.
