What this 55-inch UHD signage display is for

The LG 55UH5Q-GQ is a 55-inch signage panel with a 3840 x 2160 native resolution, designed to run for long hours in public and business spaces. It belongs to the UH5Q series of standard UHD and FHD signage models, so it suits organisations that need a dependable screen for menus, promotions, wayfinding and announcements. Its panel life is listed at 50,000 hours minimum and its operation is rated 24/7.

Picture and panel facts that matter day to day

The panel uses edge backlighting in a 16:9 format, with 500 nit typical brightness and a 1,200:1 typical contrast ratio. The dynamic contrast figure is 1,000,000:1. It reproduces 1.07 billion colours using 8-bit plus FRC, covering 95% of BT709 and 80% of DCI-P3. A 178 x 178 viewing angle keeps content readable when viewers approach from the side, which matters in corridors and lobbies. The 8 ms typical grey-to-grey response time and 60Hz refresh rate suit moving graphics and video loops. The surface has a 25% typical haze value, which describes how much light the surface diffuses.

Connectivity, software and control

Three HDMI inputs and one DisplayPort input each accept 3840 x 2160 at 60Hz with HDCP 2.2 and 1.4. The display also offers two USB 2.0 Type A ports, an RJ45 LAN port, RS232C input and output, an IR input, and an audio output. The built-in webOS 8.0 platform, with 16GB of eMMC storage, handles scheduling, local content and playback without a separate media player. Features such as group management, fail over, playback via URL, tile mode up to 15 x 15, SNMP and Wake on LAN help IT teams manage several screens from one place. SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud and Mobile CMS are listed as compatible; SuperSign itself must be purchased separately.

Where it fits across Qatar

In a shopping mall or retail store in Msheireb or West Bay, a row of these panels can carry the same promotion or split into zones with schedules set by time of day. In a bank branch or government service centre in Doha, a 55-inch screen above a waiting area can show queue information and announcements, and the on-screen menus support both English and Arabic. In a hotel lobby or serviced apartment building in The Pearl or Lusail, it can present guest information and wayfinding, and its 11.4 mm even bezel keeps a multi-panel wall looking uniform.

What to plan before ordering

Mounting: the VESA interface is 300 x 300. A slim bracket leaves about 13.5 mm between the panel and the wall. Optional Slim Wall Mount (WB21LMA/B) and Normal Wall Mount (OLW480A/B) are listed.
Weight: the head weighs 14.3 kg and the packed unit 18.1 kg, so plan for two people and a wall fixing rated for that load.
Environment: operating temperature is 0 °C to 40 °C at 10% to 80% humidity. In summer, confirm that the mounting position stays within this range, especially in areas that are not air-conditioned.
Power: the built-in power supply accepts AC 100-240V at 50/60Hz, drawing a typical 103W and a maximum of 154W.
Site survey: SmartRooms Qatar offers free site surveys, which are useful before fixing a panel to a lobby or corridor wall.

Questions about 55UH5Q-GQ

What is the LG 55UH5Q-GQ used for?

It is a 55-inch UHD signage display for showing menus, promotions, wayfinding and information in shops, offices, lobbies and public areas. With a 3840 x 2160 native resolution and a 24/7 operation rating, it is built for content that plays all day rather than occasional presentations. It suits organisations that want a standard signage screen driven by a content management system rather than a meeting-room display.

Is 55 inches the right size for my space in Qatar?

A 55-inch panel suits a corridor, reception wall, retail aisle or small waiting area where viewers stand a few metres away. For large atriums or lecture halls, the same UH5Q-G series is listed in 86, 75, 65, 49 and 43-inch sizes, so compare options against viewing distance before you request a quote. SmartRooms Qatar can confirm the right size during a free site survey.

Do I need a separate media player?

No. The webOS 8.0 platform runs the display's own content, with 16GB of eMMC storage, local content scheduling, USB plug and play, and playback via URL. Group management, fail over and a no-signal image help keep a site running when a source drops. Your content workflow still needs a suitable content management solution, which is covered in the next question.

Which SuperSign software works with it?

The display is listed as compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Connected Care. SuperSign must be purchased separately, so choose the version that fits your number of screens and how your team manages content, then include it in your quotation request.

How would a shopping mall in Msheireb or West Bay use it?

A retail team can place several panels along a walkway and use group management to send the same promotion to all screens, or split them into zones with different schedules by time of day. Local content scheduling lets each panel follow its own timetable, so a weekend offer can replace a weekday one without visiting each screen.

Can a bank branch or government service centre in Doha use it for queues?

A 55-inch screen above a waiting area can show queue information, service announcements and guidance in English and Arabic, since the on-screen menus support both languages. Mount it at a height and distance where seated visitors can read it comfortably. Schedules can change service information by counter or time of day, which keeps public messages current during busy periods.

Would it work in a hotel lobby in The Pearl or Lusail?

Yes, it suits guest information, wayfinding and event listings in a lobby. The 11.4 mm even bezel keeps a multi-panel wall looking uniform, and the 178 x 178 viewing angle keeps text readable from the side as guests walk past. Arrange a site survey before fixing the wall mount so the panel is aligned with lighting and sightlines.

How does Qatar's summer heat affect it?

The specified operating temperature range is 0 °C to 40 °C, with humidity between 10% and 80%. Summer temperatures in Qatar can go above 45°C, so the display must sit in a space that stays within that range. Confirm the location with the SmartRooms Qatar team during the site survey, particularly for windows, outdoor-facing lobbies and unconditioned areas.

What wall mount and clearance does it need?

The panel uses a 300 x 300 VESA mounting interface. With the slim bracket, it sits about 13.5 mm from the wall. Optional wall mounts are the Slim Wall Mount (WB21LMA/B) and Normal Wall Mount (OLW480A/B). Check that the wall can carry the 14.3 kg head weight and allow space for cable access, since the design includes simple cable management.

How much does the panel weigh and how is it packed?

The head weighs 14.3 kg and the packed unit weighs 18.1 kg. The carton measures 1360.0 x 810.0 x 152.0 mm, and the monitor measures 1240.1 x 711.9 x 29.7 mm. Plan for two people to carry and lift it, and check lift access, stairwells and doorways before delivery is arranged.

How much power does it use?

Typical consumption is 103W and maximum is 154W, with 72W listed for smart energy saving at 70%. Standby and power-off draw are each 0.5W. The built-in power supply accepts AC 100-240V at 50/60Hz, so plan one outlet per panel at the mounting position and confirm the outlet location in your quotation request.

Can we buy through a purchase order or government tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, for the LG 55UH5Q-GQ. Payment can be made by bank transfer, cheque or purchase order. Quotations are usually issued within one working day, and the product is covered by the manufacturer's warranty.
