LG 55UM5N-E (Discontinued) · Replacements in Qatar

Name: LG 55UM5N-E 55-inch UHD Signage Display
Brand: LG
SKU: lg-55um5n-e
Availability: Discontinued

Overview

A 55-inch UHD signage display with a 3840 x 2160 IPS panel, 500 nit typical brightness and webOS 6.0 for 24/7 operation. This model has been discontinued by the manufacturer, so SmartRooms Qatar can quote a current or compatible replacement. It suits lobbies, corridors and reception areas in Doha, Lusail and Education City that need a narrow-bezel screen with built-in Wi-Fi.

What the 55UM5N-E is and why it matters

The LG 55UM5N-E is a 55-inch UHD signage display built around a 3840 x 2160 IPS panel. It is designed to run content for long periods, which makes it suitable for menus, wayfinding, announcements and information boards. The manufacturer has discontinued this model, so buyers who already own one, or who are comparing it with newer options, should know that SmartRooms Qatar can quote for a current equivalent or a compatible replacement.

The panel is rated for 24/7 operation with a minimum lifetime of 50,000 hours. That suits sites where a screen stays switched on around the clock, such as reception areas and transit halls.

Picture quality and panel facts for busy public spaces

The panel delivers 500 nit typical brightness with a direct backlight, a BT709 95% colour gamut and 10-bit colour depth, which gives around 1.07 billion colours. Viewing angles are rated at 178 degrees horizontally and vertically, so content stays readable from several positions in a lobby or corridor. Points worth checking with your facilities or IT team include:

Response time of 8 ms rise and 10 ms fall
Surface haze value of 0.28
Portrait and landscape orientation supported
Auto brightness sensor fitted

Connectivity, networking and content management

The display offers three HDMI inputs and one DisplayPort input, each supporting 3840 x 2160 at 60 Hz. An HDMI output at 30 Hz and a daisy-chain connection pass the signal on to the next screen. Control is possible through RS232C, RJ45 LAN and IR input, and a USB 2.0 Type A port allows content to be loaded locally.

Built-in Wi-Fi and Bluetooth, 16GB eMMC storage and webOS 6.0 support local content scheduling, group management, tile mode up to 15 x 15 and remote management with SNMP and Wake on LAN. The unit is compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud and Mobile CMS, and it is listed as Crestron Connected.

Where it fits in Qatar

Three realistic settings show how this display is typically used:

A hotel lobby in West Bay, where one screen at reception shows guest welcome content and event schedules, updated from a central content manager.
A university building in Education City, where corridor screens display room timetables and campus announcements across several floors, managed as one group.
A government reception in Msheireb, where menus appear in English and Arabic through the on-screen display, and visitor information is loaded by USB or over the network.

What to plan before ordering

Installation planning starts with the environment. The operating range is 0 to 40 degrees Celsius with 10% to 80% humidity, and summer temperatures in Qatar can pass 45 degrees Celsius. Install the unit indoors in air-conditioned space with clear airflow, away from direct sunlight and outdoor enclosures, and confirm your location with the SmartRooms Qatar team. The IP5X rating indicates dust protection, which is not the same as suitability for outdoor use.

The head weighs 14.2 kg and uses a 300 x 300 VESA mounting interface. Optional mounts include the WB21LMA/B slim wall mount, the OLW480A/B wall mount and the AM-B330S wall mount adapter. Power is AC 100-240V at 50/60 Hz, with a typical draw of 130 W and a maximum of 180 W. A power cord is included, but the source data does not list the plug type, so confirm it before ordering. For several screens or a long wall, a free site survey helps confirm the layout. Quotations are usually issued within one working day, and government bodies and schools can order by LPO.

Send SmartRooms Qatar your room dimensions, viewing distance and number of screens, and request a quote for a current equivalent or compatible replacement that matches your requirement.

Questions about 55UM5N-E

Is the LG 55UM5N-E still available from SmartRooms Qatar?

The manufacturer has discontinued this model, so the quotation focus is on a current equivalent or a compatible replacement. Tell the SmartRooms Qatar team the screen size, resolution, software features and number of units you need. The team will then recommend an option and send a quotation, usually within one working day.

What is the 55UM5N-E designed for, and where does it suit?

It is a 55-inch signage display with a 3840 x 2160 IPS panel, rated for 24/7 operation and built to show menus, wayfinding, announcements and information boards. It suits corridors, reception areas and lounges where one screen must run for long hours, such as a school entrance in Al Rayyan or a hotel lobby in Doha.

How bright is the screen, and will it work in a sunlit lobby?

The panel is rated at 500 nit typical brightness, with a direct backlight and a surface haze value of 0.28. An auto brightness sensor is fitted. In a lobby with large windows facing the sun, position the screen away from direct glare, and request a site survey so the mounting position can be checked before installation.

Does it support 4K content from media players and laptops?

Yes. The unit has three HDMI inputs and one DisplayPort input, each supporting 3840 x 2160 at 60 Hz. HDCP 2.2 is supported on both the HDMI and DisplayPort inputs. A media player or laptop can connect directly to any of these inputs for 4K playback.

Can several units be linked into a video wall in a long corridor?

Yes. Tile mode supports layouts up to 15 x 15 screens, and the daisy-chain connection passes HDMI or DisplayPort input to the next display. The bezels measure 12.4 mm at the top and bottom and 11.4 mm at the sides, which reduces the visible seam. A long corridor wall needs a planned layout, so request a site survey before ordering.

What software runs on the display, and how is content managed?

The display runs webOS 6.0 and has 16GB of eMMC storage. It supports local content scheduling, group management, USB plug and play and playback via URL. It is compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud and Mobile CMS, so a facilities team can update screens from a central system.

Does the on-screen display support Arabic?

Yes. The on-screen display languages include Arabic alongside English and many other languages. This suits organisations that work in Arabic and English side by side, such as government offices and schools in Doha. Test your own Arabic and English content files on the unit before rollout.

How much power does it draw, and does it suit Qatar's mains supply?

The power input is AC 100-240V at 50/60 Hz, with a built-in power supply. Typical consumption is 130 W and maximum is 180 W, and 91 W with smart energy saving at 70 percent. A power cord is included, but the plug type is not listed in the source data, so confirm the plug and socket arrangement with the SmartRooms Qatar team before ordering.

Can it be installed in a hot outdoor area or near summer sun?

The operating range is 0 to 40 degrees Celsius with 10% to 80% humidity, and the IP5X rating provides dust protection. Summer temperatures in Qatar can exceed 45 degrees Celsius, so install the unit indoors in air-conditioned space, away from direct sunlight and outdoor enclosures. Ask the team to confirm your specific location before buying.

How heavy is it, and which wall mounts fit?

The head weighs 14.2 kg and the packed weight is 18.9 kg. It uses a 300 x 300 VESA interface. Optional mounts are the WB21LMA/B slim wall mount, the OLW480A/B wall mount and the AM-B330S wall mount adapter. A government reception in Msheireb should have the wall and mount height checked during a free site survey before fitting.

Can it be tilted face down for a counter or lift lobby?

The data lists a face-down tilt of up to 30 degrees, with that rating tied to a 40 degree Celsius ambient temperature. Tilt helps with low counters and close sightlines, but it does not replace correct mounting height. Confirm the mount, angle and ambient conditions with the SmartRooms Qatar team before installation.

Can several screens across a multi-floor campus be managed from one place?

Yes. The unit has an RJ45 LAN port, SNMP support, Wake on LAN and Group Manager, and it is listed as Crestron Connected. A university building in Education City with screens on several floors can be managed as one group from a central system. Large groups need a clear network plan, so define requirements before installation.
