LG 50UL3Q-E 50-inch UHD Digital Signage Display

Overview

The LG 50UL3Q-E is a 50-inch UHD signage display with a 3840 x 2160 panel, 350 nit typical brightness and webOS 6.1. Its brightness sensor adjusts output to room light, and built-in Wi-Fi supports remote monitoring of networked units. It suits lobbies, corridors, retail floors and meeting-room signage in Doha and Lusail, and it runs in portrait or landscape. Ask for a quote for one unit or a multi-screen order.

What the 50UL3Q-E is built for

The LG 50UL3Q-E is a 50-inch UHD signage display from the UL3Q series, made for showing information in indoor public and staff areas. Typical uses include welcome screens, wayfinding, queue and appointment displays, menu boards and corporate messages. At 50 inches it suits corridors, reception walls and small atriums, where a larger panel would dominate the space.

Picture and brightness facts that matter

The VA panel has a native resolution of 3840 x 2160 in a 16:9 format, so small text on menus and directories stays sharp at close range. It is rated at 350 nit typical brightness, with a 4,500:1 contrast ratio, 10-bit colour depth and DCI 80% colour gamut. The 8 ms grey-to-grey response time suits moving content, and the 25% haze surface treatment reduces reflections in brightly lit rooms.

Auto brightness: a front-mounted sensor adjusts output to the room's light level.
Orientation: runs in portrait or landscape for vertical menus and corridor signs.
Audio: two built-in 10 W speakers and an audio output.

Software, control and remote monitoring

The display runs webOS 6.1 with 8GB of internal eMMC memory, so scheduled playlists can run on the unit itself. The source data lists built-in Wi-Fi and Bluetooth, local contents scheduling, group management, tile mode settings, fail over and play via URL. It is compatible with SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud and Mobile CMS. Facilities teams can monitor units from a phone or PC, view current and past data, and control them in real time. Crestron Connected, SNMP and Wake on LAN support integration with wider control systems.

Where it fits in Qatar

Government counter area in Doha: service information and notices on a screen at each counter or waiting zone, managed from one network.
Private school in Al Wakrah: corridor screens for timetables, events and announcements, with the auto brightness sensor adjusting to daylight from windows.
Retail unit in Msheireb or Lusail: an interior wall showing promotions, with portrait mode suiting vertical product panels and the screen kept away from direct sunlight.

What to plan before you order

Mounting uses a 200 x 200 VESA interface, and the panel tilts up to 15 degrees face up and 15 degrees face down. The manufacturer warns against exceeding that range, so confirm mounting height and angle during a site survey. Operating conditions are 0 °C to 40 °C with 10% to 80% humidity, and portrait use is limited to 0 °C to 35 °C. Summer temperatures in Qatar can exceed 45 °C, so install the unit only in air-conditioned indoor spaces. The power supply accepts 100-240V at 50/60Hz, covering Qatar's 240 V, 50 Hz mains. Typical consumption is 90 W and maximum is 152 W, which matters when sizing circuits for several screens.

Questions about 50UL3Q-E

Who is the LG 50UL3Q-E designed for?

It suits organisations that need an indoor signage screen of about 50 inches for reception areas, corridors, meeting-room approaches and staff areas. It is a display for scheduled information rather than an interactive screen, since the source data lists no touch function. Facilities managers and school leaders often choose this size where an 86-inch panel would overpower the wall. A quote can confirm the right number of units for your floor plan.

What resolution and panel type does it use?

The panel is a VA type with a native resolution of 3840 x 2160 (UHD) and a 16:9 aspect ratio. It is rated at 350 nit typical brightness, 4,500:1 contrast and 10-bit colour depth, with DCI 80% colour gamut. The UHD resolution keeps menu text, room directories and small logos sharp when people stand close, such as at a reception counter or a clinic check-in desk.

Can it play content without a separate media player?

Yes. The unit runs webOS 6.1 and has 8GB of internal eMMC memory. The source data lists local contents scheduling, USB plug and play, play via URL and gapless playback, so a screen can run its own playlist. Larger estates usually add a content management system such as SuperSign CMS, which the product is listed as compatible with. Ask the SmartRooms Qatar team which setup suits your sites.

How does the brightness sensor help in a bright lobby?

The front-mounted auto brightness sensor adjusts screen output to match ambient light, so the picture does not wash out in a daylit atrium or look harsh in a dim corridor. Typical brightness is 350 nit, so the sensor helps but does not replace good planning. Keep the screen out of direct sunlight, and avoid placing it opposite a large window where midday sun hits the glass.

Can it be mounted in portrait orientation?

Yes, the source data lists both portrait and landscape operation. Portrait suits vertical menus, queue information and corridor signage. Note that the portrait operating range is narrower: 0 °C to 35 °C, against 0 °C to 40 °C in landscape. In an office or school with reliable air conditioning this is manageable, but confirm the room's cooling capacity during the site survey.

Can it be installed outdoors or on a sunny terrace in Qatar?

No. The listed operating range is 0 °C to 40 °C with 10% to 80% humidity, and it does not cover outdoor conditions. Summer temperatures in Qatar can exceed 45 °C, which is above this range. Install the unit inside air-conditioned spaces only, and avoid walls facing windows where sun heat builds up. For any outdoor or semi-outdoor requirement, ask SmartRooms Qatar to confirm suitable equipment first.

How does remote monitoring work for a business with several branches?

The source data describes web-based monitoring from a mobile phone or PC, with real-time control and access to current and past data. A head office can check whether each screen is running and adjust its settings. Status mailing, SNMP and Wake on LAN are also listed. For a retailer with branches in Al Sadd, Al Rayyan and Lusail, this can reduce site visits, though network access requirements should be confirmed during the survey.

Which ports and audio connections does it have?

The connection list includes one HDMI input with HDCP 2.2 and 1.4 support, one RS232C input and one RS232C output for serial control, two USB 2.0 Type A ports and one audio output. It has no touch USB function. Two 10 W speakers are built in. Plan one HDMI source per screen, and check the cable route before ordering so the RS232C and audio runs match the mounting position.

What should we check before mounting it?

The panel uses a 200 x 200 VESA mount interface and can tilt up to 15 degrees face up or 15 degrees face down. The manufacturer warns not to exceed that range to prevent damage, so set the angle carefully when mounting above eye level in a lobby. Check the wall structure, cable route and power point, and book a free site survey with SmartRooms Qatar before drilling. Professional installation is also available.

How much power does it use, and will it run on Qatar's mains supply?

The power supply is listed as 100-240V at 50/60Hz with built-in power, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 90 W and maximum is 152 W, while the Smart Energy Saving mode is listed at 63 W. For a school or office fitting several screens, these figures help size circuits and estimate running costs. A power cord is included with the unit.

Can it be used in a video wall?

The source data lists a tile mode setting and a 10.8 mm even black bezel, so the unit can form part of a multi-screen layout. A video wall also needs a suitable content source and a mounting frame that suits every panel. A narrow frame reduces the visible gap between panels, which helps wall graphics. Confirm the layout and quantity before ordering, and ask for a quote covering all components.

Can we order through an LPO for a government or school project?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including those on Monaqasat, and payment by bank transfer, cheque or purchase order. Quotations are usually issued within one working day. Send the quantity, mounting locations and LPO details, and the quotation will reflect a single unit or a multi-unit order. The product is covered by the manufacturer's warranty.
