Overview

The LG 55UL5Q-E is a 55-inch UHD signage display with a 3840 x 2160 panel, 500-nit typical brightness and a 24/7 operating rating.

Its even 10.8 mm bezels and portrait support suit school corridors, hotel lobbies and office reception areas in Doha and beyond. Request a quote from SmartRooms Qatar.

What the 55UL5Q-E is built to do

The LG 55UL5Q-E is a 55-inch UHD signage display from the UL5Q series, designed to show menus, timetables, wayfinding and promotional content on screens that run for many hours each day. Its 3840 x 2160 panel uses a 16:9 aspect ratio and a 60Hz refresh rate, and the panel is rated for 24/7 operation with a minimum lifetime of 30,000 hours.

This is a display-only unit. The data does not list touch input, so it suits reception screens, information points and corridor signage where the content manager, rather than the viewer, controls what appears.

Picture, brightness and mounting facts that matter

Typical brightness is 500 nit, and a front-mounted sensor adjusts the output to match the lighting in the room. This helps in lobbies where daylight changes through the day. Viewing angles are rated at 178 degrees horizontally and vertically, the colour gamut is listed as DCI 80%, and the panel supports 1.07 billion colours.

Bezel: 10.8 mm even black bezels for tidy layouts when screens sit side by side.
Orientation: portrait and landscape operation, with portrait rated at 0 °C to 35 °C.
Tilt: up to 15 degrees up or down, and this range must not be exceeded.
Dimensions: 1234.2 x 706.7 x 58.9 mm, with a head weight of 12 kg.

Software, connectivity and security

The unit runs webOS 6.1 with 8GB of internal memory, built-in Wi-Fi and Bluetooth, and a wired LAN input. Administrators can schedule local content, group displays, play media from a URL, and monitor and control units remotely in real time from a phone or PC. Security features include LG's Enhanced Kernel Protection, and the data cites ISO/IEC 15408 Common Criteria EAL2 certification. The model is also EPEAT Bronze, registered in August 2025.

Where it fits in Qatar

A private school in Al Rayyan fitting out a new corridor can use a 55-inch panel for timetables and announcements, with Arabic menus set on the display if staff prefer them. A ministry office in Msheireb with a visitor lobby can show service directions and queue information. A hotel or serviced apartment building in The Pearl can use portrait mode for a directory beside the lift. Each location should be an air-conditioned indoor space, because the operating range tops out at 40 °C.

What to plan before ordering

The VESA interface is 300 x 300 mm, and the packed weight is 16.2 kg, so the wall, fixings and bracket must suit the load. Optional wall mounts WB21LMA/B and WB24GCA/B are available. The typical power draw is 124W and the maximum is 190W. Our free site survey checks wall condition, viewing height, power access and cable routing before installation. The extended warranty and LG ConnectedCare are optional and can be discussed in your quotation.

Questions about 55UL5Q-E

Where does the 55UL5Q-E suit best in Qatar?

It suits corridors, reception areas, classroom entrances and visitor lobbies where a 55-inch screen can show timetables, wayfinding or announcements. A school in Al Rayyan fitting out a corridor, or a ministry office in Msheireb with a visitor lobby, would normally choose a panel of this size on a wall at eye level. Its 3840 x 2160 resolution keeps small text readable at close range.

Is the 55UL5Q-E rated for continuous use?

Yes. The panel is rated for 24/7 operation with a minimum lifetime of 30,000 hours, which suits a lobby or wayfinding screen that runs through the working day and into the evening. The operating temperature range, covered in the next answer, defines where it can run. Tell us your daily run hours when you request a quote so we can check the setup.

How hot can the room be for this display?

The operating range is 0 °C to 40 °C, or 0 °C to 35 °C in portrait orientation, with 10% to 80% humidity. Qatar summers regularly pass 45 °C outside, so the screen should sit in an air-conditioned interior, away from direct sun and window glare. An open entrance or covered outdoor area is not a suitable location. Our team will confirm ventilation during the free site survey.

Can I mount it in portrait orientation?

Yes. The data lists portrait and landscape operation, so the same panel can run as a tall digital totem or a menu board. Portrait operation is rated for 0 °C to 35 °C, which is 5 °C lower than landscape, so a tall screen in a warm corridor needs careful placement. A shopping mall in Lusail might use portrait mounting beside a store entrance. Request a quote and we will confirm the mounting height.

What can I connect to it?

The inputs are three HDMI ports (HDCP 2.2 and 1.4), one RJ45 LAN input, RS232C control in and out, two USB 2.0 Type A ports and an audio output. It does not provide DisplayPort, DVI-D, RGB, HDMI output, USB touch or daisy chaining. A school sending media from a PC and a network player can use the HDMI and LAN ports, while the USB ports suit content loaded from a flash drive.

Can several units be linked into a video wall?

The software lists a tile mode setting, but the data does not list daisy chaining, and the unit has no HDMI output for passing a signal to the next panel. Each screen therefore needs its own feed from a source. A multi-panel wall in a hotel lobby at The Pearl would need planned cabling and source equipment. The bezel is 10.8 mm, so joins are narrow. Share your layout and we will confirm the wiring before you order.

Which content management systems work with it?

The software compatibility list includes SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Connected Care. On the display itself, local content scheduling, group management, play via URL, four video tags and four-window PBP mode are available under webOS 6.1. A property manager in a Doha serviced apartment building could schedule notices from the office and send them to several screens at once.

Does the on-screen menu support Arabic?

Yes. The on-screen display language list includes Arabic alongside English and many other languages. That suits a Doha office or school where staff work in Arabic and English side by side. Set the OSD language during commissioning so the menus match the people managing the screen. The language setting controls the menus only, so bilingual messages must be prepared in the content management system.

What warranty applies, and what is ConnectedCare?

The 55UL5Q-E carries the standard warranty LG applies to its signage models, and an optional extended warranty covers up to 5 years in total. Extended cover ends when 30,000 hours of use are reached or the five-year period expires, whichever comes first. LG ConnectedCare is a separately purchased cloud service for remote fault diagnosis, and its availability differs by region. We will confirm availability in Qatar with your quotation.

How much power does it use?

The typical draw is 124W and the maximum is 190W, with Smart Energy Saving listed at 86.8W. The mains input is 100-240V AC at 50/60Hz, so it accepts the 240 V, 50 Hz supply used in Qatar. At the typical 124W, a display running 24 hours uses roughly 3 kWh a day. Ask us to confirm the supplied power cord and socket arrangement in your quotation.

What should we plan before installing one?

Plan for a wall that suits a VESA 300 x 300 mm mounting interface, a head weight of 12 kg and a packed weight of 16.2 kg, with overall dimensions of 1234.2 x 706.7 x 58.9 mm. Optional wall mounts WB21LMA/B and WB24GCA/B are listed. Tilt adjusts up to 15 degrees. SmartRooms Qatar offers a free site survey, so an office in Lusail or a site in Al Khor can be checked for wall, height and power before the screen is fixed.
