LG 75UH5Q-GQ 75-inch 4K UHD Digital Signage Display

Overview

Built for long hours in business settings, the 75-inch LG 75UH5Q-GQ combines a 3840 x 2160 UHD panel, 500 nit typical brightness and webOS 8.0 with 16GB internal memory, so content can run without a separate media player. It is rated for 24/7 operation and supports portrait and landscape use. It suits lobbies, reception areas and retail entrances in Doha, Lusail and West Bay that need a reliable screen for menus, wayfinding and announcements.

What the 75UH5Q-GQ Is Built to Do

The LG 75UH5Q-GQ is a 75-inch 4K UHD signage display from LG's UH5Q series, aimed at organisations that need a screen to run menus, wayfinding, announcements and promotional content for long hours. The manufacturer rates it for 24/7 operation and lists a minimum panel lifetime of 50,000 hours, which matters for screens that run all day in a lobby or corridor.

Picture Figures Worth Checking Before You Buy

The native resolution is 3840 x 2160, four times the pixel count of Full HD, so small text on menus and floor plans stays legible at reading distance. The panel is rated at 500 nit typical brightness, 1,200:1 typical contrast and 25% typical surface haze. It shows 1.07 billion colours (8-bit + FRC), covers 95% of BT709 and 80% of DCI-P3, has a 178 x 178 viewing angle and an 8ms typical grey-to-grey response. The 1,000,000:1 dynamic contrast figure is a dynamic-mode rating, so compare it with the 1,200:1 typical figure when weighing other panels.

Connections and Content Management

The built-in webOS 8.0 platform runs signage playlists without a separate media player, backed by 16GB of internal memory. Ports include three HDMI inputs and one DisplayPort input, all supporting 3840 x 2160 at 60Hz with HDCP 2.2 and 1.4. You also get RS232C input and output for daisy-chained control, an RJ45 LAN port, an IR input, two USB 2.0 Type A ports and an audio output. Tile Mode Setting supports grids up to 15 x 15, and PIP and PBP are available with one external input. The unit is compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Connected Care, so you can choose the approach that suits how many sites you manage.

Where It Fits in Qatar

Hotel lobby or serviced apartment reception in West Bay or The Pearl: showing check-in information, events and directions, with content scheduled locally on the display.
Clinic waiting area in Al Sadd: displaying queue information and instructions, with portrait mounting where the corridor is narrow.
Corporate or government reception in the Industrial Area or Lusail: presenting organisation information and visitor guidance, with the on-screen menu available in Arabic.

What to Plan Before You Order

The head weighs 35.7 kg and the packed weight is 44 kg, with monitor dimensions of 1679.5 x 958.7 x 29.7 mm excluding the IR sensor and handle. Use the VESA 600 x 400 mounting interface and confirm the wall can carry the load, or the optional LSW640A/B wall mount. The operating range is 0 °C to 40 °C with 10% to 80% humidity, so install the screen in an air-conditioned room. Qatar's summer outdoor temperatures can exceed 45 °C, so confirm room conditions with the SmartRooms Qatar team before installation. The built-in power supply accepts 100-240V AC at 50/60Hz, typically draws 162W and peaks at 243W, and the power cord is included. SmartRooms Qatar offers free site surveys before wall mounting, professional installation, and quotations usually within one working day, with purchase orders (LPOs) and government tenders accepted.

To request a quote for the LG 75UH5Q-GQ, send the number of units, the room size and the planned wall location to the SmartRooms Qatar team, who will reply with a quotation usually within one working day.

Questions about 75UH5Q-GQ

Who is the LG 75UH5Q-GQ best suited for?

The LG 75UH5Q-GQ suits organisations that need a 75-inch screen for menus, wayfinding, announcements and promotional loops over long hours. In Qatar that means a hotel lobby in West Bay, a clinic waiting area in Al Sadd or a retail entrance in Lusail. Its 3840 x 2160 resolution keeps text readable from a comfortable viewing distance, and its 24/7 operation rating covers all-day use.

Do I need a separate media player?

Usually not. The webOS 8.0 platform runs signage content on the display itself, backed by 16GB of internal memory. Local content scheduling lets you set playback on the unit, and USB Plug and Play lets staff load content from a USB device through either of the two USB 2.0 Type A ports. Check your content format and playback requirements with SmartRooms Qatar before ordering.

Is 500 nit bright enough for a lobby with large windows?

The panel has a typical brightness of 500 nit, so direct sunlight through glass can wash out the picture. Place the screen away from the window line, avoid facing it into glare, and check sightlines during a free site survey. The 25% typical surface haze treatment helps reduce reflections, but it does not replace careful positioning.

What are the key panel specifications?

The 75-inch 16:9 panel has a 3840 x 2160 native resolution and a 60Hz refresh rate. It shows 1.07 billion colours, covers 95% of BT709 and 80% of DCI-P3 colour gamut, and has a typical grey-to-grey response of 8ms. The viewing angle is 178 x 178, and the manufacturer rates the panel lifetime at a minimum of 50,000 hours.

Can it be installed in portrait orientation?

Yes. The source confirms support for both portrait and landscape orientation, and the unit includes screen rotation and external input rotation settings. Portrait mode suits corridor directories, lift-lobby information and menu boards in restaurants at Msheireb or The Pearl. Decide the orientation before ordering, because it determines how the mount is fixed to the wall.

How heavy is it, and what should I check before wall mounting?

The head weighs 35.7 kg and the packed weight is 44 kg, so at least two people should lift it. The VESA mounting interface is 600 x 400, and the LSW640A/B wall mount is optional. Confirm the wall structure can carry the load and book a free site survey before drilling. SmartRooms Qatar can coordinate professional installation.

Can it handle Qatar's summer heat?

The operating temperature range is 0 °C to 40 °C with 10% to 80% humidity, so it should be installed in an air-conditioned room rather than a hot entrance or open courtyard. Summer outdoor temperatures in Qatar can exceed 45 °C. Confirm cooling and airflow at the chosen spot with the SmartRooms Qatar team before installation, especially for a room with a sun-exposed glass front.

Can several units form a video wall?

Yes. Tile Mode Setting supports grids up to 15 x 15, so multiple 75-inch units can be arranged into a larger wall for a hotel lobby or event hall. The bezel width is 12.9 mm (even), which keeps seams tidy. Ask SmartRooms Qatar to confirm the grid layout, control planning and cabling before you order the number of units.

What connections does it have?

The display has three HDMI inputs and one DisplayPort input, all supporting 3840 x 2160 at 60Hz with HDCP 2.2 and 1.4. It also has RS232C input and output, an RJ45 LAN port, an IR input, two USB 2.0 Type A ports and an audio output. RS232C input and output allow IR daisy-chaining for control, while the unit itself has no IR output port.

Which signage software works with it?

It is compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Connected Care. Choose the platform that matches how many sites you manage and whether you want cloud-based control. The unit also supports Wake on LAN and SNMP for remote monitoring. Confirm the software version you need when you request a quote.

Can staff change settings in Arabic?

Yes. The on-screen display menu includes Arabic alongside English, French, German, Spanish and many other languages. This helps Arabic-speaking staff in government offices and schools adjust the screen without relying on an English menu. Confirm with SmartRooms Qatar how your Arabic content will display, because this answer covers the menu language only.

How much power do several units use, and can a school order them together?

Typical consumption is 162W and maximum is 243W, and Smart Energy Saving reduces typical use to 113W. The built-in power supply accepts 100-240V AC at 50/60Hz, and the power cord is included. A school in Al Wakrah fitting out several corridors can issue one LPO covering all units, and SmartRooms Qatar supplies all eight municipalities. Request a quote with the number of units.
