Overview

What the 55UM5N-H is built for

The LG 55UM5N-H is a 55-inch signage display with a 3840 x 2160 IPS panel, giving four times the resolution of Full HD. Its 16:9 screen is rated for around-the-clock operation, and the manufacturer lists a panel life of at least 50,000 hours. It is designed for menus, wayfinding, news loops, schedules and promotional content in places where the screen must stay lit through the working day.

Picture and screen facts that matter

The panel delivers 500 nit typical brightness, a 1,100:1 contrast ratio and 10-bit colour with a BT709 95% colour gamut. A 28% haze anti-glare surface reduces reflections from windows and overhead lights, which matters in lobbies and shopfronts. The 178 x 178 viewing angle keeps content visible from the side of a corridor. The screen rotates between portrait and landscape, so one unit can show a tall menu board or a wide timetable.

Platform, connectivity and content control

webOS 6.0 runs signage applications directly on the display, so many installations do not need a separate media player. The unit has 16GB internal memory, built-in Wi-Fi, a wired RJ45 LAN port and a built-in speaker. Inputs include three HDMI ports, one DisplayPort, one USB 2.0 Type A port and RS232C control, plus an HDMI output and daisy-chain support for passing a signal to the next screen. That output runs at 3840 x 2160 at 30Hz, so plan the chain around that limit. Compatible software includes SuperSign CMS, SuperSign Cloud, SuperSign Control and Mobile CMS.

Where it fits in Qatar

A 55-inch panel suits a clinic waiting area, a bank branch wall showing queue numbers, a hotel lobby or a directory at the entrance of a shopping mall. In a private school in Al Wakrah, a unit by the main entrance can display timetables and announcements. Several units can be combined in Tile Mode, which supports up to 15 x 15 displays, to form a video wall for a retail atrium or a control room at a logistics firm in the Industrial Area.

Durability and environment planning

The unit carries an IP5x rating, has a conformal coating on its power board that protects against salt, dust, iron powder and humidity, and includes shock monitoring. The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summers can exceed 45°C, so install the display in an air-conditioned room where the temperature stays within that range. Do not place it in an unconditioned outdoor kiosk or a sun-exposed space without a cooling plan, and confirm the location with the SmartRooms Qatar team during the site survey.

Power, mounting and installation planning

Power input: AC 100-240V, 50/60Hz, which covers Qatar's 240V mains.
Typical consumption 130W and maximum 180W; Smart Energy Saving reduces typical draw to about 91W.
Dimensions 1237 x 710 x 57.7 mm; head weight 14.2 kg, so check wall structure and fixings.
VESA 300 x 300 mount; the optional slim bracket WB21LMA/B leaves about 13 mm from the wall.
Tilt face-down up to 30 degrees, with the 40°C rating applying to that setting.

Certifications listed for this model include CB/NRTL safety, FCC Class B, CE and KC EMC marks, ErP and Energy Star. If a government tender names a specific certificate, check it against this list before submitting.

Questions about 55UM5N-H

What is the LG 55UM5N-H best suited for?

The LG 55UM5N-H is a 55-inch UHD display built for digital signage, such as menus, wayfinding, announcements and promotional loops. It suits indoor spaces with steady air conditioning, like a bank lobby in West Bay or a clinic waiting room in Al Sadd. Its 24/7 rating and 500 nit typical brightness make it practical for daily content loops that must run through business hours.

Can it play content without a separate media player?

Yes. The webOS 6.0 platform with its high-performance SoC is designed to run multiple tasks on the display itself, so many installations do not need a separate media player. The unit also has 16GB internal memory and built-in Wi-Fi, so schedules and content can be managed on the screen. Check your video library size against the 16GB memory before planning long loops.

Is the screen bright enough for a shopfront or atrium in Doha?

The panel has 500 nit typical brightness and a 28% haze anti-glare surface that reduces reflections. That suits indoor areas lit by daylight through glazing, such as a retail atrium in The Pearl or a hotel lobby in Msheireb. Screens facing direct sunlight through windows still need careful placement, which a site survey will assess before installation.

Can several units be joined into a video wall?

Yes. Tile Mode supports up to 15 x 15 displays, and the bezels measure 12.4 mm at top and bottom and 11.4 mm at the sides. A three-by-two wall of these 55-inch panels could serve a control room at a logistics company in the Industrial Area or a meeting centre in Education City. Each unit needs its own power and network planning, which the site survey will cover.

What temperature range can it operate in during Qatar summers?

The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summers can exceed 45°C, so the display should be installed in an air-conditioned room where the temperature stays within this range. It is not suitable for a covered outdoor walkway or a sun-exposed kiosk without a cooling plan. Confirm the exact location with the SmartRooms Qatar team before ordering.

What does the IP5x rating mean for dusty sites?

IP5x indicates protection against dust ingress, and the conformal coating on the power board adds protection against salt, dust, iron powder and humidity. This helps in workplaces near the Industrial Area or Mesaieed, where airborne dust settles on electronics. The rating does not make the display suitable for outdoor use, so an air-conditioned indoor location is still the right choice.

Can it be mounted close to the wall?

Yes, with the right bracket. The VESA mount is 300 x 300, and the optional slim wall mount WB21LMA/B leaves about 13 mm between the display and the wall. The head weighs 14.2 kg, so the wall structure and fixings need checking. SmartRooms Qatar offers free site surveys to confirm wall type, cable routing and placement before installation.

What inputs and outputs does it provide?

It has three HDMI inputs, one DisplayPort input, one USB 2.0 Type A port, RS232C input and output, an RJ45 LAN port, an IR input and an audio output. It also has an HDMI output and daisy-chain support for passing a signal to the next display, although that output runs at 3840 x 2160 at 30Hz. Plan the chain length with this limit in mind.

Can the on-screen menus be set in Arabic?

Yes. The on-screen display language list includes Arabic alongside English, French, German, Spanish and many others. Offices in Doha that work in Arabic and English side by side can set menus in either language. Your content layouts still depend on how you design the templates, so agree on bilingual layouts before the screen goes live.

What power supply does it need in Qatar?

The power input is AC 100-240V at 50/60Hz, which covers Qatar's 240V, 50Hz mains. Typical consumption is 130W and maximum consumption is 180W, and Smart Energy Saving reduces typical draw to about 91W. A power cord is included in the basic accessories. Confirm the socket and plug arrangement with your installer before fitting the unit.

Which certifications does this model carry?

The manufacturer data lists CB/NRTL safety, FCC Class B, CE and KC EMC marks, ErP and Energy Star, and a Carbon Trust entry. It also cites ISO/IEC 15408 Common Criteria EAL2 certification for information security. If your tender requires a specific certificate, compare it with this list before you submit your bid.

How do I order it through an LPO or a government tender?

SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. Quotations usually arrive within one working day. When you request a quote, state the model 55UM5N-H exactly, and add the WB21LMA/B slim bracket if you need a flush wall installation.
