Overview

Its 12.9 mm even black bezels suit video walls and retail windows, while a built-in brightness sensor adjusts output to room lighting. Businesses in Doha, Lusail and across Qatar can request a quote.

What the LG 75UL3Q-E is built to do

The LG 75UL3Q-E is a 75-inch display from the UL3Q series, built for information and advertising content in public-facing spaces. Its 3840 x 2160 panel and 16:9 aspect ratio keep text and images sharp when people read from a few metres away. The manufacturer rates it for 16 hours of operation per day, seven days a week, which fits lobbies, corridors, waiting areas and retail floors that run long opening hours.

Picture and brightness figures that matter on site

Brightness: 350 nit typical, with a front-mounted sensor that adjusts output to the lighting in the room.
Contrast: 1,200:1 static, with a dynamic contrast figure of 1,000,000:1 listed.
Viewing angle: 178 degrees horizontal and 178 degrees vertical.
Response and refresh: 8 ms grey-to-grey response and a 60 Hz refresh rate.
Surface and life: 1% haze surface treatment and a panel life of at least 30,000 hours.

The panel reproduces DCI 80% colour gamut and 8-bit colour with FRC, which is suitable for brand graphics and video loops. The black frame and low-haze surface help the screen stay readable in a bright reception area when the brightness sensor adjusts the output.

Software, control and remote management

The unit runs webOS 6.1, with local content scheduling, group management, USB plug and play, fail over, screen rotation, tile mode setting and playback via URL. Its specification also lists a web-based remote monitoring function, which lets staff check status and adjust the display from a phone or PC, with access to current and past data. Compatible software in the data includes SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Crestron Connected. The on-screen menu offers Arabic and English, among other languages, which helps bilingual teams.

Where it fits in Qatar

Hotel lobby in The Pearl or Msheireb: a landscape display showing wayfinding, event listings and guest information, with the menu set to English or Arabic.
Government reception in Doha: a display running service information in both languages, managed by a small facilities team across the building.
Retail store in West Bay: a portrait display for promotional loops and product messages, placed in an air-conditioned interior away from direct sunlight.

What to plan before ordering

The monitor measures 1679.7 x 958.9 x 58.5 mm and uses a 400 x 400 VESA mounting interface. The manufacturer lists a head weight of 24.1 and a packed weight of 31.6, and the carton measures 1875 x 175 x 1145 mm, so confirm the wall and bracket rating before mounting. Operating temperature is 0 to 40 degrees Celsius, or 0 to 35 degrees in portrait mode, with humidity between 10 and 80 percent. Summer temperatures in Qatar can exceed 45 degrees, so the display belongs in an air-conditioned indoor space. Typical power draw is 155 W and maximum is 227 W, with standby at 0.5 W. A free site survey from SmartRooms Qatar can check the wall, the viewing distance and the power route before installation.

Questions about 75UL3Q-E

Where is a 75-inch UHD signage display like the 75UL3Q-E typically used in Qatar?

It suits spaces where people stop and read from a few metres away, such as a hotel lobby in The Pearl, a corporate reception in Lusail or a bank branch in Doha. The 3840 x 2160 panel keeps text and images sharp at that distance, and the manufacturer rates it for 16 hours of operation per day. Confirm the mounting position and room lighting during a free site survey before ordering.

Can I put the LG 75UL3Q-E near a window or outdoors where summer heat exceeds 45°C?

No, not outdoors or in unconditioned spaces. The rated operating temperature is 0 to 40°C, or 0 to 35°C in portrait mode, with humidity between 10 and 80 percent. Summer temperatures in Qatar can exceed 45°C, so install it in an air-conditioned indoor area and keep it out of direct sunlight. Confirm the exact position with the SmartRooms Qatar team before you request a quote.

Does the display work in portrait orientation for digital menus or wayfinding?

Yes. The manufacturer lists portrait and landscape operation, which suits vertical wayfinding boards in a mall corridor or a menu board at a café counter. In portrait mode the operating range narrows to 0 to 35°C, so plan the location accordingly. The up and down tilt is limited to 15 degrees, and the manufacturer warns not to exceed that range.

What happens to scheduled content if the network connection drops?

The specification lists local contents scheduling, local network sync and fail over, so the unit can keep playing its stored schedule rather than relying only on a live connection. It also supports USB plug and play for playback from a memory device. Confirm the exact fail over behaviour with the manufacturer documentation and your IT team before you depend on it for a public-facing screen.

Can the on-screen menus be set to Arabic for a ministry or public counter?

Yes. The on-screen display language list includes Arabic alongside English, so a government reception or a bilingual service desk can set the menu language to suit staff. Content language is separate and depends on the files you publish. Set up the menu with the included remote and check it in both languages during handover.

How do facilities teams monitor several displays across Doha from one place?

The webOS platform supports web-based remote monitoring from a phone or PC, with access to current and past data. Staff can adjust settings and control the unit in real time. The software list includes SuperSign CMS, SuperSign Control+, SuperSign Cloud, Mobile CMS and Crestron Connected, so a multi-site operator can match the management tool to its network. Confirm which tools you need when requesting your quote.

How narrow are the bezels for a video wall at a mall or event venue?

The bezel is 12.9 mm, even on all sides, and black. Even bezels keep the gaps between tiled displays uniform, which matters in a mall atrium or a stadium concourse wall. The monitor measures 1679.7 x 958.9 x 58.5 mm and has a 400 x 400 VESA mounting interface, so plan the grid and spacing during a free site survey. The software list also includes a tile mode setting.

What is the power consumption and is it compatible with Qatar's electrical supply?

The power supply is listed as AC 100 to 240 V, 50/60 Hz with built-in power, which covers Qatar's 240 V, 50 Hz supply. Typical consumption is 155 W and maximum is 227 W. The energy-saving mode is listed at 108.5 W and standby at 0.5 W. Confirm the socket and cable route with your installer, since the unit ships with a power cord.

Which ports and inputs does the 75UL3Q-E provide for a meeting room or lobby setup?

It has three HDMI inputs with HDCP 2.2 and 1.4 support, one RS232C input, one RS232C output, one RJ45 LAN port, two USB 2.0 Type A ports and an audio output. RS232C control suits integration with a room controller. The three HDMI inputs let you connect a media player, a laptop and a second source without swapping cables.

What security features does the display include for sensitive corporate or government content?

The UL3Q uses LG's Enhanced Kernel Protection technology to guard against unauthorised access, and its security architecture is validated by ISO/IEC 15408 Common Criteria EAL2 certification. The unit also includes built-in Wi-Fi and Bluetooth, 8GB of internal memory, and Wake on LAN and SNMP support. IT teams should review network settings and access policy before deployment.

Can a government department buy this display on an LPO or through a Monaqasat tender?

Yes. SmartRooms Qatar supplies on purchase orders (LPOs) and government tenders, including Monaqasat, and accepts payment by bank transfer, cheque or purchase order. Quotations are usually issued within one working day, and a free site survey can confirm the mounting position before you commit. Lead times are confirmed with the quotation, based on stock.

What comes in the box with the LG 75UL3Q-E?

The accessory list includes a remote controller with two batteries, a power cord, a regulation book, an easy setup guide, a warranty card and a phone to D-Sub 9 adapter. The display is covered by the manufacturer's warranty. Mounting hardware is not listed in the accessory data, so confirm the bracket and fixings with your installer after the wall survey.
