A 50-inch UHD signage display for continuous wall-mounted use

The LG 50UL5Q-M is a 50-inch signage display built on a 3840 x 2160 VA panel. It is designed for corridors, lift lobbies, clinic waiting areas and branch counters where a screen shows wayfinding, queue information or promotional content through the working day. The 500 nit typical brightness, 178 by 178 degree viewing angle and 4,500:1 contrast ratio keep content readable for people who approach from different sides of the room.

Specifications that shape the buying decision

Three details matter most when comparing this model. The panel is specified for 24/7 operation with a minimum life of 50,000 hours, so it suits displays that run all day rather than only during office hours. The even 10.8 mm black bezel keeps the frame uniform, which helps when several screens sit side by side on one wall. The display also works in landscape or portrait, which is useful for totems and narrow lobbies.

Inside, webOS 6.1 with 8GB of internal memory runs the content. Built-in Wi-Fi and Bluetooth, a LAN port and an RS232C control connection allow the screen to join a network or be controlled by an external system. Three HDMI inputs and two USB 2.0 Type A ports cover most media players and drives. A built-in brightness sensor adjusts output to the room, and temperature and gyro sensors are also fitted. Two 10 W speakers are included.

Where it fits in Qatar

A private clinic in Al Sadd installing one screen in a waiting area to show department locations and visiting guidance, mounted at a height suited to seated and standing viewers.
A school in Al Wakrah fitting out corridors with several screens in portrait for timetables and notices, with content updated from the administration office.
A bank branch in West Bay placing a landscape screen beside the counters for service announcements in Arabic and English.

The built-in Arabic on-screen menu helps teams that work in both languages set up the unit. In every case the screen should sit indoors in an air-conditioned space, because the operating range is 0 to 40 °C, or 0 to 35 °C in portrait. Qatar summer heat can exceed 45 °C outdoors, so keep the screen out of direct sun coming through glazing.

What to plan before installation

VESA mounting pattern of 200 x 200 mm, with the head weighing 9.3 kg and the packed unit 12.2 kg.
Monitor size of 1120.2 x 641.4 x 59.9 mm and carton size of 1255 x 760 x 118 mm, for delivery and storage planning.
Tilt of up to 15 degrees up or down; the manufacturer advises against exceeding this range.
Power input of 100-240 V AC at 50/60 Hz, with typical consumption of 115 W and maximum of 174 W.
Optional wall mounts LSW240A/B and slim WB21LMA/B, with fit to be confirmed in the quotation.

The box includes a remote controller with two batteries and a power cord. A free site survey lets our team check the wall type, load, cable route and viewing height before any bracket is fixed. Delivery reaches all eight municipalities of Qatar, and professional installation can be arranged.

Questions about 50UL5Q-M

Who is the LG 50UL5Q-M for?

It suits organisations that need one or a few wall-mounted screens for information or promotion in a medium-sized space, such as a clinic reception, a school corridor or a bank branch. The 50-inch UHD panel can be read from several metres away, yet the head weighs 9.3 kg and uses a 200 x 200 mm VESA pattern, so it fits a standard wall bracket.

Can it run continuously in a busy reception?

Yes. The panel is specified for 24/7 operation with a minimum life of 50,000 hours. For a reception that runs all day, plan the content schedule using the built-in local content scheduling and rely on the brightness sensor to adjust output. Keep the room air-conditioned, since the operating range is 0 to 40 °C, and ask our team to check the layout before you buy.

Can the display be mounted in portrait orientation?

Yes. The panel supports portrait and landscape, which suits menu boards, wayfinding totems and narrow lift lobbies. Portrait operation is rated for 0 to 35 °C, which is narrower than the 0 to 40 °C landscape range, so confirm the site temperature before mounting vertically. The unit tilts up or down by up to 15 degrees to bring the screen to eye level, and the manufacturer advises not to exceed that.

Is it suitable for a window-facing or sunlit location in Doha?

Direct sun and high heat can push the screen beyond its rated range. The data gives an operating range of 0 to 40 °C and humidity of 10 to 80 percent. Qatar summer temperatures can exceed 45 °C, so the screen should sit in an air-conditioned indoor space away from direct sunlight. Confirm the exact position with the SmartRooms Qatar team before the installation is quoted.

What inputs and ports does it have?

The LG 50UL5Q-M has three HDMI inputs with HDCP 2.2 and 1.4 support, one LAN port, RS232C input and output, two USB 2.0 Type A ports and an audio output. It has no DisplayPort input, no RGB input, no HDMI output and no daisy-chain connection, so each screen needs its own signal source, such as a media player, a PC or a compatible device.

Which software can manage the display?

The compatibility list includes SuperSign CMS, SuperSign Control+, SuperSign WB, SuperSign Cloud, Mobile CMS and Connected Care. Built-in features include local content scheduling, group manager, video tag, four-way PBP split screen, failover and play via URL. Choose the platform based on how many screens you run and whether content is updated on site or from a central office.

Can we monitor and control it remotely?

Yes. The web-based remote monitoring lets authorised users check status, make adjustments and control the unit in real time from a mobile phone or PC over the network, with access to current and past data. Network features include SNMP and Wake on LAN. The optional LG ConnectedCare cloud service is sold separately and its availability depends on region.

Does the on-screen menu support Arabic?

Yes, Arabic is listed among the on-screen display languages, alongside English, French, Chinese and others. That helps teams that run signage in Arabic and English side by side, such as government offices, hospitals and schools in Qatar. The menu language is separate from your content, so the design team should still check how Arabic text renders in their own files.

What wall mount and space do I need?

The VESA pattern is 200 x 200 mm and the monitor measures 1120.2 x 641.4 x 59.9 mm, weighing 9.3 kg without packaging. The optional mounts listed for this model are the LSW240A/B wall mount and the slim WB21LMA/B. We will confirm the mount fit and cable route in the quotation, and a free site survey is recommended for walls that will carry the weight.

What power does it need?

The built-in power supply accepts 100-240 V AC at 50/60 Hz, so it is compatible with Qatar's 240 V, 50 Hz mains. Typical power draw is 115 W and maximum is 174 W, and smart energy saving reduces typical use to about 80.5 W. Standby use is 0.5 W. Plan a Type G socket near the mounting point and a cable route that stays clear of heat sources.

What warranty applies?

The product is covered by the manufacturer's warranty. The source notes that an optional extended warranty is available, providing coverage for up to five years in total, which ends when either 50,000 hours of usage or the five-year period is reached, whichever comes first. The standard warranty period is not stated in the data, so we will confirm the applicable terms in your quotation.

How do we buy several units for a school or government office through an LPO?

SmartRooms Qatar accepts purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. For a school fitting out several corridors, send the quantity, mounting heights and a room list. After a free site survey, quotations are usually issued within one working day. Lead times are estimates confirmed with the quotation, based on stock.
