LG 75UL5Q-E 75-inch UHD Digital Signage Display

Overview

The LG 75UL5Q-E is a 75-inch UHD signage display designed for 24/7 operation, with 3840 x 2160 resolution, 500-nit typical brightness and a 12.9 mm even bezel. Built-in webOS 6.1, three HDMI inputs, LAN control and an auto brightness sensor suit lobbies, corridors, showrooms and meeting areas across Qatar where content must run around the clock.

What the 75UL5Q-E is built for

The 75UL5Q-E is a 75-inch UHD display from LG's UL5Q series, made for signage that runs through long opening hours. Its 3840 x 2160 panel suits sharp text, fine detail and product imagery, and the panel is specified for 24/7 operation with a lifetime of at least 30,000 hours. It is a standard signage model for information screens, menu boards and content walls.

Picture, sensing and build details

The panel offers 500 nit typical brightness, a 1,200:1 contrast ratio and a 178 degree viewing angle both horizontally and vertically, so people standing at the side of a corridor still see the content clearly. It reproduces 1.07 billion colors with 80% DCI colour gamut coverage and an 8 ms grey-to-grey response. The auto brightness sensor adjusts output to the room lighting. The even 12.9 mm black bezel keeps the frame uniform, the display works in landscape or portrait, and up and down tilt adjustment brings the screen toward eye level.

Connectivity, software and remote control

Inputs: three HDMI inputs with HDCP 2.2 and 1.4, one RJ45 LAN input, two USB 2.0 Type A ports and an audio output.
Serial control: RS232C in and out for control and sync across units.
Software: webOS 6.1 with local content scheduling, group management, fail over, picture-in-picture and four-way picture-by-picture, plus SuperSign CMS, SuperSign Control+, SuperSign Cloud and Mobile CMS compatibility.
Wireless and storage: built-in Wi-Fi and Bluetooth with 8GB of internal eMMC memory.

Remote monitoring is web-based, so staff can check status and adjust settings from a phone or PC on the network. The display has no DisplayPort input, no HDMI output and no daisy-chain option, so plan your media player and cabling around the three HDMI inputs and the LAN connection.

Where it fits in Qatar

A hotel lobby in West Bay showing arrival times, event listings and wayfinding from early morning to late evening.
A private school in Al Wakrah fitting out new corridors with timetables and notices, using the two built-in 10 W speakers for short announcements.
A clinic reception in Msheireb displaying queue information and health messages during working hours.

Qatar's summer heat raises indoor temperatures, so the operating range matters. The panel is rated for 0 °C to 40 °C, or 0 °C to 35 °C in portrait orientation, with 10% to 80% humidity. Install it in an air-conditioned space, check the room against these limits before ordering, and confirm the location with the SmartRooms Qatar team. The built-in power supply accepts 100 to 240 V AC at 50 or 60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical draw is 188 W and maximum draw is 268 W.

Planning the mount, certifications and warranty

Head weight 24.1 kg, packed weight 31.6 kg, dimensions 1679.7 x 958.9 x 58.5 mm.
VESA mounting interface 400 x 400 mm. The source data does not list stand weight or dimensions, so confirm stand requirements in your quotation.
Listed certifications: CB/NRTL safety, FCC Class B, CE and KC for EMC, and EPEAT Bronze registered in August 2025.
Covered by the manufacturer's warranty. An optional extension runs up to five years in total, ending at 30,000 hours or five years, whichever comes first.
LG ConnectedCare is an optional cloud service, bought separately, with availability that varies by region.

A free site survey is worth booking before wall-mounting a panel of this weight, to check the wall and cable routing. Schools, hotels and offices ordering several units can raise a purchase order (LPO), and government tenders are welcome. Request a quote from SmartRooms Qatar, usually answered within one working day. We will confirm delivery to all eight municipalities of Qatar, installation and estimated lead time with the quotation.

Questions about 75UL5Q-E

Who is the LG 75UL5Q-E designed for?

It suits organisations that need a 75-inch display for content running through long hours, such as reception areas, corridors, waiting areas and retail floors. Its UHD panel is specified for 24/7 operation, which makes it a practical choice for schools, hospitals and hotels in Doha that want information screens running from morning until late evening.

Can the 75UL5Q-E run 24 hours a day in Qatar?

The source specifies 24/7 operation and a panel lifetime of at least 30,000 hours. The operating range is 0 °C to 40 °C, so the display should sit in an air-conditioned room, and the room temperature should be checked against that limit before installation, particularly in summer. Confirm the location with the SmartRooms Qatar team when you request a quote.

What is the operating temperature in portrait orientation?

In portrait orientation the operating range narrows to 0 °C to 35 °C, while the landscape range reaches 40 °C. Humidity should stay between 10% and 80%. A portrait screen in an open atrium exposed to afternoon sun needs its ambient temperature checked carefully, and a site survey can confirm the conditions before the display is ordered.

What video inputs does the 75UL5Q-E have?

It has three HDMI inputs with HDCP 2.2 and 1.4 support, one RJ45 LAN input, two USB 2.0 Type A ports and an audio output. It has no DisplayPort, DVI-D, RGB or HDMI output, so a laptop that only offers DisplayPort will need an adapter. Plan your media player connections around the three HDMI inputs.

Can I manage content on several 75UL5Q-E displays from one place?

Yes. The display supports group management, local content scheduling and fail over, and it is compatible with SuperSign CMS, SuperSign Control+, SuperSign Cloud and Mobile CMS. Web-based remote monitoring lets staff check status and make adjustments from a phone or PC. For a school spread across several floors, ask which platform suits your network when you request a quote.

Does the 75UL5Q-E work with Qatar's electrical supply?

The built-in power supply is rated for 100 to 240 V AC at 50 or 60 Hz, which covers the 240 V, 50 Hz mains used in Qatar. Typical power draw is 188 W and maximum draw is 268 W, and Smart Energy Saving mode is listed at 131.6 W. Confirm the plug and socket arrangement with your installer during the site survey.

How heavy is the panel, and what mount does it need?

The head weighs 24.1 kg, the packed weight is 31.6 kg, and the dimensions are 1679.7 x 958.9 x 58.5 mm. It has a 400 x 400 mm VESA mounting interface. The source data does not list stand weight or stand dimensions, so ask us to confirm floor or wall stand requirements in your quotation. A site survey helps check the wall before fixing.

How many screens can a school order on a purchase order?

A school fitting out several classrooms or corridors can raise one purchase order (LPO) for the full quantity, and SmartRooms Qatar can quote for multiple 75UL5Q-E units in a single request. Decide the mounting positions first, so the quotation reflects each location. Quotations are usually issued within one working day.

Is the display suitable for a hotel lobby in West Bay?

Yes. A hotel lobby in West Bay can use the 75UL5Q-E for arrival messages, event listings and wayfinding. The 500 nit typical brightness and auto brightness sensor help content stay readable as daylight through glass changes, and the 178 degree viewing angle keeps screens clear for guests standing at the side of the lobby. Check the temperature near the entrance before installation.

What warranty applies to the 75UL5Q-E?

The display is covered by the manufacturer's warranty. The source lists the same standard warranty period as other signage models, plus an optional extended warranty covering up to five years in total. Extended cover ends at 30,000 hours of use or five years, whichever comes first. The standard warranty duration is not stated in the data, so ask for the exact terms in your quotation.

What does LG ConnectedCare add, and is it included?

ConnectedCare is an optional cloud service that remotely checks display status for fault diagnosis and remote control. It must be purchased separately, and availability differs by region. If you want it, include it in your quote request so the team can confirm whether it is available for your site in Qatar.

Does the 75UL5Q-E have built-in speakers?

Yes, it has two built-in 10 W speakers and an audio output. They suit short announcements or background audio in a corridor or reception area. For a lecture hall or large meeting room, a separate audio system fed from the audio output is the better option.
