Overview

The LG 55UH5J-H is a 55-inch UHD signage display with a 500 nit typical brightness, a 28% haze surface that reduces reflections, and 24/7 operation rating. It has three HDMI inputs, Wi-Fi and Bluetooth, webOS 6.0, and IP5X dust protection with a conformal-coated power board. It suits airport gates, retail floors and shopping mall atriums in Qatar, where content must hold attention. Request a quote from SmartRooms Qatar.

What the 55UH5J-H does in busy public spaces

The LG 55UH5J-H is a 55-inch standard signage display with a 3840 x 2160 UHD resolution and an IPS panel. Its 178º x 178º viewing angle keeps the picture readable for people standing beside a lobby or walking past a store window. The panel is rated for 24/7 operation with a minimum life of 50,000 hours, which suits screens that run promotions, wayfinding or flight information from opening to closing time.

Brightness, contrast and haze

Typical brightness is 500 nits, with a 1,100:1 contrast ratio, 1.07 billion colours and a BT709 95% colour gamut. The surface carries a 28% haze finish. Haze diffuses light, so reflections from ceiling fittings and glazing are softened, but fine text can look slightly softer than on a glossy screen, so keep text-heavy content at a comfortable reading distance. The data does not list a direct sunlight rating, so a screen facing a sunlit window should be reviewed before ordering.

Protection, temperature and power planning

Operating temperature 0 °C to 40 °C and humidity 10% to 80%.
IP5X dust protection, plus a conformal coating on the power board that guards against salt, dust, iron powder and humidity.
Built-in power supply accepting AC 100-240V at 50/60Hz.
Typical draw 110W, maximum 150W, and 77W in Smart Energy Saving mode.

Qatar summer temperatures can exceed 45 °C, which is above this rated range. Install the display in air-conditioned rooms, keep it clear of direct heat sources, and confirm conditions with the SmartRooms Qatar team before fixing it on a wall that faces a sunlit window or a hot external surface.

Connections and content management

Three HDMI inputs, one DisplayPort input and a DVI-D input accept signals from a media player or laptop. The HDMI output passes the signal to the next display, so a row of screens can share one source. RS232C in and out, IR in, a LAN port and a USB 2.0 Type A port support control and local media. Built-in Wi-Fi and Bluetooth, 16GB internal memory and webOS 6.0 are included. The software list covers SuperSign CMS, SuperSign Cloud, Mobile CMS, Connected Care and Crestron Connected. The display has no built-in OPS slot, but it is listed as compatible with OPS piggyback use, and the optional OPS Kit KT-OPSF is available.

Where it fits in Qatar

Gate and concourse screens near Hamad International Airport showing retail offers and flight times.
A shopping mall in Lusail updating promotions from one cloud content system across several units.
A ministry reception in Msheireb showing visitor information, with on-screen menus available in Arabic.

Planning the installation

The head weighs 19.0 kg, or 19.6 kg with the ST-653T stand, and the packed weight is 24.2 kg, so plan for two installers and a secure bracket. The display measures 1234.4 x 720.9 x 39.9 mm and uses a 300 x 300 mm VESA interface; the LSW350B wall bracket is an optional accessory. Bezels are 9.9 mm on the top, left and right and 14.4 mm at the bottom. Tilt downward is up to 30 degrees, and portrait or landscape use is supported. A free site survey before wall mounting confirms wall load, cable routes and the correct bracket.

Questions about 55UH5J-H

What is the LG 55UH5J-H designed for?

It is a 55-inch UHD signage display for indoor public and corporate use, rated for 24/7 operation with a 500 nit typical brightness. It suits airport concourses, retail floors and shopping mall walkways where content must be read from a distance. Meeting rooms and reception areas also work well where information or marketing loops run through the working day.

Is 500 nits bright enough for a lobby with windows in Doha?

The panel is rated at 500 nits typical with a 28% haze surface, which softens reflections from glazing. The data does not list a direct sunlight rating, so a screen placed opposite a sunlit window should be reviewed first. SmartRooms Qatar offers a free site survey to check the position, lighting and viewing distance before you order.

Can it run in summer in a space without air conditioning?

No. The operating range is 0 °C to 40 °C with 10% to 80% humidity, while Qatar summer temperatures can exceed 45 °C. Use it in air-conditioned rooms such as meeting rooms, lobbies and retail floors, and confirm the environment with the SmartRooms Qatar team before installing near entrances, windows or semi-outdoor areas.

Does it work with Qatar's 240 V mains supply?

The built-in power supply accepts AC 100-240V at 50/60Hz, which covers the 240 V, 50 Hz supply used in Qatar. The source data does not state the plug type, so confirm that the included power cord suits BS 1363 (Type G) sockets when you request your quote.

How many devices can I connect to one display?

There are three HDMI inputs, one DisplayPort input and a DVI-D input. The HDMI output passes the signal to the next display, so a row of screens in a hotel lobby can share one source. RS232C in and out, IR in, one RJ45 LAN port and a USB 2.0 Type A port are also provided for control and local media.

Can I add an OPS media player to this model?

The display has no OPS slot built in. It is listed as compatible with OPS piggyback use, and the manufacturer lists an optional OPS Kit, KT-OPSF. Confirm the kit and the player you intend to use when requesting a quote, so the correct bundle is priced and supplied.

How do we manage content across several branches?

The software list includes SuperSign CMS, SuperSign Cloud, Mobile CMS, SuperSign Control+, Connected Care and Wake on LAN, with SNMP and status mailing. A retailer with branches across Doha and Al Rayyan can update content centrally and receive status alerts. Confirm the network and security requirements with your IT team before connecting the units.

Can it be controlled from a meeting room AV system?

Yes. The data states Crestron Connected support for network-based control, and RS232C and IR inputs provide additional control options. A boardroom or a university room in Education City can therefore integrate the display into an existing control system. SmartRooms Qatar can confirm the control set-up for your system.

Does the 55UH5J-H support touch input?

No. The source data lists no touch USB and no overlay touch compatibility, so this is a non-touch display. For interactive use in a lobby or training room, an interactive or touch display would be a better fit, and SmartRooms Qatar can quote suitable alternatives.

What wall space and mounting does it need?

The head weighs 19.0 kg and measures 1234.4 x 720.9 x 39.9 mm. It uses a 300 x 300 mm VESA pattern, and the LSW350B wall bracket is an optional accessory. Plan for a load-bearing wall, two installers and cable routing for HDMI and LAN runs. A free site survey before mounting confirms these details.

We are a government entity and need several units under an LPO. Can we order through a tender?

Yes. SmartRooms Qatar handles purchase orders (LPOs) and government tenders, including Monaqasat, for the LG 55UH5J-H. State the quantity, bracket choice and whether you need the OPS kit in your request. Quotations are usually issued within one working day, and payment can be made by bank transfer, cheque or purchase order.
