55UH5C

What the LG 55UH5C is

The LG 55UH5C is a 55-inch Ultra HD display made for digital signage, used for menus, schedules, wayfinding and promotional loops in lobbies, corridors and waiting areas. The manufacturer has discontinued this model, so this page serves three groups: organisations already running one, buyers comparing it with newer signage displays, and anyone who needs a current equivalent or a compatible replacement.

Its 3,840 x 2,160 panel delivers four times the definition of Full HD, and its 500 cd/m² brightness keeps content clear in well-lit indoor spaces. The listed variant code is 55UH5C-B.

Connections, control and built-in Wi-Fi

Video inputs include HDMI, DisplayPort, DVI-D and an SD card slot, alongside USB 3.0 and audio input. A DisplayPort output and an external speaker output are provided. For building management, the display offers RS232C, RJ45, an IR receiver and a pixel sensor. Built-in Wi-Fi supports sharing content over a network and a Soft AP mode in which the display acts as a wireless access point for mobile devices.

The quad-core SoC handles content playback, and the display supports HEVC-encoded material, which the manufacturer states can roughly halve network traffic compared with H.264. It is compatible with SuperSign-w lite and SuperSign-c software and accepts OPS-type modules. The optional OPS Kit (KT-OPSA) and the external media players MP500 or MP700 extend the content delivery options.

Power, heat and physical planning

• Typical power consumption of 116 W, reduced to 80 W in smart energy saving mode
• M+ panel technology, which the manufacturer says cuts power use by approximately 31% compared with conventional RGB panels
• Operating temperature 0°C to 40°C and operating humidity 10% to 80%
• Power supply 100-240V, 50/60Hz with built-in power
• Bezels of 12.1 mm at the top, 12.6 mm on each side and 15.7 mm at the bottom
• Monitor dimensions 1,239.8 x 725.2 x 38.6 mm and head weight 16.6 kg

The 40°C upper limit is the key planning point in Qatar, where summer temperatures often exceed 45°C. Keep this display in air-conditioned rooms, away from direct sunlight, glazed entrances and unconditioned loading areas, and confirm the exact environment with the SmartRooms Qatar team before fixing it to a wall. Its 100-240V supply range covers Qatar's 240 V, 50 Hz mains.

Where it fits in Qatar

A bank branch in West Bay might mount one 55-inch panel in its customer lobby to show service information, wayfinding and promotional loops. The 500 cd/m² brightness suits a well-lit indoor lobby, and the 38.6 mm depth keeps the screen close to the wall.

A private school in Al Wakrah refitting its ground-floor corridors could use it for timetables and event notices. The 16.6 kg head and slim profile make wall mounting practical, though the 1,239.8 mm width calls for two installers.

A clinic in Al Sadd could show queue numbers and health information in its waiting area, with the screen placed away from windows that receive afternoon sun.
