LG 55UH5N-M 55-inch UHD Digital Signage Display

Overview

The LG 55UH5N-M is a 55-inch UHD digital signage display with a 3840 x 2160 panel, 500 nit typical brightness and an anti-glare surface. It runs webOS 6.0 with 16GB of internal storage and built-in Wi-Fi, so playlists can run without a separate media player. Rated for 24/7 operation, it suits lobbies, corridors and reception areas in Doha, West Bay and Lusail where wayfinding and announcements matter.

What the LG 55UH5N-M is built to do

The LG 55UH5N-M is a 55-inch UHD display made for digital signage: menu boards, wayfinding, visitor information and internal communication screens that run for long hours. It belongs to the UH5N standard signage series, so it suits organisations that need a dependable screen with a practical specification rather than an interactive panel or a video wall built from ultra-narrow bezels.

The 3840 x 2160 native resolution provides four times the pixels of a full HD screen, so small text and fine graphics stay sharp at normal reading distance in a corridor or lobby. The panel is rated for 24/7 operation with a 50,000-hour minimum life.

Picture and visibility figures that matter

Typical brightness is 500 nit, with a 1,200:1 contrast ratio and a 25% haze anti-glare surface. In a bright atrium or near a window, that surface reduces reflections so the content stays legible. Viewing angles are listed at 178 degrees horizontally and vertically, so people approaching from the side can still read a notice. The refresh rate is 60Hz and the colour gamut is listed at BT.709 95%.

Portrait and landscape orientation are both supported, which suits a tall directory beside a lift or a wide banner above a reception desk.

Running content without an external media player

The unit has 16GB of internal memory, built-in Wi-Fi and Bluetooth, and runs webOS 6.0. Playlists can be scheduled locally and synchronised across a group of screens, with picture-in-picture, up to four picture-by-picture windows and tile mode for walls up to 15 by 15 displays. Management runs through SuperSign CMS, Control+, WB, Cloud or Mobile CMS. Inputs are three HDMI, one DisplayPort, one LAN, two USB 2.0 Type A ports, RS232C in and out, IR input and audio output, with 10W x 2 speakers built in. It also includes Enhanced Kernel Protection and is listed as ISO/IEC 15408 Common Criteria EAL2 certified.

Where it fits across Qatar

Hotel lobbies in West Bay: guest information, dining offers and transport times, updated from one office and shown beside the front desk.
Private schools in Al Rayyan or Al Wakrah: corridor displays for timetables, achievement notices and bilingual announcements.
Clinic waiting areas in Doha: queue numbers and health awareness messages, scheduled to loop through the day.
Malls and retail in Lusail: store directories and promotions running around the clock.

Planning the installation in Qatar

Qatar summers regularly pass 45°C, but this model is rated for 0 to 40°C operation and 10 to 80% humidity. Place it in an air-conditioned interior, not an open entrance or terrace. The face-down tilt is rated up to 15 degrees, and only at 40°C. The IP5X rating and conformal-coated power board help against dust and humidity, but they do not make it an outdoor unit.

The head weighs 16.1 kg and packs at 20.5 kg, so plan for two installers. The slim bracket leaves about 13 mm between the panel and the wall, and hidden power inlets allow close mounting. The VESA pattern is 300 x 300; optional mounts include the WB21LMA/B slim wall mount and OLW480A/B wall mount. Mains input is AC 100 to 240 V, 50/60 Hz. Certifications listed include FCC Class B, CE, KC and Energy Star.

SmartRooms Qatar offers a free site survey before wall-mounting, to check wall loading, cable routes and socket positions in Doha or any of the eight municipalities. Send your room plan and content needs, and request a quote; quotations usually arrive within one working day.

Questions about 55UH5N-M

What is the LG 55UH5N-M best used for?

The LG 55UH5N-M suits information screens that change through the day, such as menu boards, wayfinding and visitor information. A hotel lobby in West Bay might place it beside the front desk to show guest information and transport times, scheduled from one office. Its 55-inch size reads clearly from a few metres away, and the 3840 x 2160 resolution keeps small text sharp.

Do I need a separate media player to run content?

For most jobs, no. The unit has a high-performance SoC and runs webOS 6.0 with 16GB of internal memory, so playlists, schedules and built-in apps can run on the screen itself. Built-in Wi-Fi and Bluetooth also support connection to external sensors and webOS partner apps. An external source can still be connected over HDMI or DisplayPort when a laptop or player is needed.

How bright is it, and will it be readable near a window?

Typical brightness is 500 nit, with a 1,200:1 contrast ratio and a 25% haze anti-glare surface that reduces reflections in bright light. That suits lobbies with daylight, but it is not a rating for direct sunlight outdoors. If the screen faces a large window in a Doha office, we recommend a site survey to check glare before the bracket is fixed.

Can it run around the clock in a busy mall or ministry lobby?

The manufacturer lists 24/7 operation and a minimum panel life of 50,000 hours. In a shopping centre in Lusail or a government reception area, that means a store directory or service information loop can run through opening hours and beyond without a separate PC. The fail-over feature in the software list helps with continuity, so confirm the setup with your IT team before installation.

Can the on-screen menu be set to Arabic?

Yes. The on-screen display language list includes Arabic alongside English and many other languages, which helps Arabic-speaking staff set up the screen locally. Arabic content itself depends on the fonts and text in your slides, so we suggest testing a sample on the panel before rollout. This matters for schools and offices that work in Arabic and English side by side.

Which inputs and ports does it have?

The model offers three HDMI inputs supporting 3840 x 2160 at 60Hz with HDCP 2.2, one DisplayPort input at the same resolution, one LAN port, two USB 2.0 Type A ports, RS232C input and output, an IR input and an audio output. That is enough to connect a laptop, a second source and an external control system in one installation.

Can I build a video wall with it?

Yes. Tile mode is listed for walls up to 15 by 15 displays. Check the bezels carefully: the side and top bezels measure 8.9 mm, while the bottom bezel is 12.9 mm, which shows as a more visible horizontal line in grid walls. For a boardroom or lobby wall, request a layout drawing and a site survey before fixing the number of units.

Is it suitable for a hot entrance or terrace in summer?

No. The operating range is 0 to 40°C with humidity from 10 to 80%, while Qatar summers regularly exceed 45°C. Place it in an air-conditioned interior such as a lobby or corridor, not an open entrance or terrace. The IP5X rating and conformal-coated power board protect against dust and humidity, but they do not make it an outdoor screen.

How close to the wall can it be mounted, and what should I plan for?

With the slim bracket, the panel sits about 13 mm from the wall, and hidden power inlets allow close mounting. The head weighs 16.1 kg, so two installers are advisable. Check the 300 x 300 VESA pattern, the optional WB21LMA/B slim wall mount and the wall's load capacity. SmartRooms Qatar offers a free site survey before a wall-mount installation.

Which software manages content on this model?

The model is compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud and Mobile CMS, and the data also lists Connected Care. SuperSign Cloud suits organisations with several branches that need one dashboard, while local scheduling and group management suit a single building. Choose the version that matches your IT policy before the screens are installed.

Is it certified for fire safety and electromagnetic compliance?

The data lists FCC Class B, CE and KC for EMC, along with ErP and Energy Star. Fire ratings are BS 476 Part 7 Class 1 for the case top and back cover, and EN 13501-1 Class A1 for the case top and Class A2 for the back cover. These figures matter for tender files and procurement reviews. SmartRooms Qatar can confirm which documents your tender requires.

Can a school or ministry order several units on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. For a school fitting out several corridors with this model, send the quantities and locations in one request so the quotation covers mounting and installation planning. Quotations usually arrive within one working day.
