55GM50D

A 55-inch 4K display for long operating days

The 55GM50D is a 55-inch indoor digital signage display with a 3840 x 2160 resolution, rated to run 18 hours a day, seven days a week. That schedule suits a reception desk, a clinic waiting room or a mall entrance that opens early and closes late. The manufacturer rates the panel lifetime at up to 50,000 hours, which gives facilities teams a clear basis for planning replacement cycles.

Picture and panel facts that shape placement

The panel uses an ADS panel type with direct LED backlighting. Typical brightness is 500 nits and typical contrast is 1,200:1. The 8 ms typical response time keeps moving content smooth, and 178-degree viewing angles on both axes mean people standing at the side of a corridor can still read the screen. A 25% haze anti-glare finish reduces reflections without a major loss of image quality. An ambient light sensor adjusts brightness to the room, which helps as light changes through the day.

• Colour depth: 1.07 billion colours (8-bit plus FRC)
• Colour gamut: 72% NTSC typical
• Refresh rate: 60Hz
• Orientation: landscape or portrait

Connections, wireless sharing and remote management

Two HDMI 2.0 inputs, one DisplayPort 1.2a input, USB 2.0 and USB 3.0 Type-A ports, and an RJ45 LAN port let you feed content from a media player, a laptop or a network source. RS232 ports on RJ45 connectors support control from an external system, and a single HDMI output can pass the signal on when a series of displays is linked from one video source. Dual-band 2.4 GHz and 5 GHz Wi-Fi (802.11 a/b/g/n/ac) and Bluetooth 5.1 are built in. The ScreenShare application lets staff share a screen wirelessly from their own devices, and the cloud-based VisionInfo platform lets administrators manage displays from any location. Android 11 runs on the display itself, so content apps need no separate PC.

Where it fits in Qatar

Three realistic setups show how the panel is used:

• A hospital or clinic in Al Sadd or Al Rayyan, where a wall-mounted panel in the waiting area displays queue numbers, health guidance and wayfinding, updated from a central office.
• A hotel lobby in The Pearl or West Bay, showing check-in details, local guides and event listings, with the panel set to portrait for a building directory layout.
• A university building in Education City, where a notice panel at the entrance carries timetables and events, managed by the IT team rather than by each department.

What to plan before ordering

The set measures 1239.7 x 710.2 x 63.3 mm and weighs 13.9 kg without packaging. It mounts to a 300 x 300 mm VESA pattern, and its narrow 10.1 mm side bezels and 10.6 mm bottom bezel suit multi-screen installations. Before the bracket is fixed, a free site survey from SmartRooms Qatar can check wall construction, cable routes and power outlet positions. The operating range is 0 to 40 C with 10% to 80% humidity, non-condensing. Qatari summer temperatures can exceed 45 C, so install the display in an air-conditioned indoor space and confirm the location with our team before installation. The IP5X rating covers dust protection; it is not a weatherproof rating. Energy Star 8.0 certification and the ambient light sensor help control running costs.

The box includes a power cord, remote controller, batteries, quick setup guide, warranty card and an RS232 (in) gender adaptor. Products are covered by the manufacturer's warranty.
