Description

This 55-inch display utilises a VA panel to deliver 3840 × 2160 resolution with a 5,000:1 contrast ratio, ensuring clear visibility in bright Omani retail or office spaces. The 12.8 mm bezel allows for tight multi-screen arrangements while the IP5X front protection guards against dust accumulation common in outdoor or semi-outdoor installations.

Operating on Android 14, the ProLite LH5566UHSB-B1AG supports direct app installation and remote management via iiSignage² CMS and iiControl DMS. Built-in Wi-Fi 5 and FailOver input switching ensure content reliability, automatically switching to backup sources if the primary signal fails, which is critical for continuous information display in ministries or hospitals.

Connectivity is handled through dual HDMI 2.0 ports, a USB-C port with 15W power delivery, and RS-232C for integration with building management systems. The display supports 24/7 operation in landscape or portrait orientation, with a VESA 400 × 400 mm mount pattern for flexible positioning in venues from Salalah to Nizwa.

Ideal for: Digital wayfinding in Muscat corporate towers, dynamic menus in Sohar hospitality venues, and public information displays for Omani government ministries requiring reliable 24/7 uptime.

  • 4K UHD Clarity – The 55-inch VA panel delivers 3840 × 2160 resolution at 60Hz, providing sharp text and vivid imagery for detailed digital menus or corporate dashboards.
  • Android 14 OS – Built-in Android 14 allows for direct application installation and remote content management via iiSignage² CMS, eliminating the need for external media players.
  • High Brightness Output – An 800 cd/m² brightness rating ensures the screen remains readable in well-lit environments, supporting clear communication in retail stores and hotel lobbies.
  • FailOver Input Switching – The display automatically detects signal loss on the primary input and switches to the next prioritised source, ensuring continuous content delivery without manual intervention.
  • IP5X Front Protection – The front panel meets IP5X standards for dust protection, making the unit suitable for harsher environments where airborne particles might affect standard displays.
  • Wireless Connectivity – Integrated Wi-Fi 5 (2.4 GHz / 5 GHz) enables reliable wireless content updates and iiShare presentations without the clutter of additional network cables.
  • 24/7 Durability – Designed for continuous operation, the display maintains performance over long duty cycles, supporting round-the-clock information displays in airports or control rooms.
  • Secure Management – Supports iiControl for device management and includes RS-232C in/out and RJ45 LAN ports for integration into existing IT and security infrastructures.
