Overview
The LG 50UL3J is a 50-inch UHD signage display with an IPS panel, 3840 x 2160 resolution and built-in webOS 6.0, so content can run without an external player. Rated 16 hours a day, 7 days a week, it suits reception areas, corridors and meeting rooms. LG has discontinued this model, so SmartRooms Qatar can quote a current equivalent or compatible replacement for organisations in Doha.
What the 50UL3J does on a signage wall
The LG 50UL3J is a 50-inch signage display built on an IPS panel with a native 3840 x 2160 UHD resolution and a viewing angle of 178 degrees both horizontally and vertically. That matters where visitors approach a reception desk, lobby or corridor from several directions, because colour and detail stay consistent away from the centre of the screen. The typical brightness is 400 nit, with a 1,200:1 contrast ratio and a 60Hz refresh rate.
Content runs from the display itself. webOS 6.0 is built in, together with 8GB of internal memory, so schedules and playlists can be managed without an external media player. Wi-Fi and Bluetooth are built in, and a web-based monitoring tool lets authorised staff check and adjust the screen from a phone or PC when the network allows it.
Connectivity and control for busy Qatari sites
- Inputs: three HDMI inputs supporting HDCP 2.2 and 1.4, one RJ45 LAN port and two USB 2.0 Type A ports
- Control: RS232C in and out for serial control, with support for Crestron Connected and Cisco certification
- Audio: two 10W built-in speakers, so announcements and video sound need no separate system
- Sensors: a built-in temperature sensor and an auto brightness sensor
Where the 50UL3J fits in Qatar
In a government ministry or authority, a 50-inch screen in a reception area can show service queues, visitor information and bilingual notices. The on-screen menu includes Arabic among more than twenty languages, which suits offices that work in Arabic and English side by side.
In a private school in Al Wakrah or Al Khor, a display in a corridor or staff room can show timetables, events and announcements, and the portrait mode suits a vertical notice board.
In a clinic or hotel lobby in West Bay or The Pearl, one panel can carry wayfinding and promotions. It is rated for 16 hours a day and seven days a week, which suits venues that open for long days.
What to plan before installation
- Weight: 11.7 kg for the head and 14.4 kg packed, so plan for a two-person lift
- Mounting: VESA 200 x 200 mm pattern
- Dimensions: 1121 x 651 x 57.1 mm, in a 1215 x 775 x 152 mm carton
- Power: built-in supply rated 100-240 V, 50/60 Hz, with typical draw of 105 W and maximum of 150 W
- Bezel: 7.3 mm on three sides and 18.4 mm on the fourth edge when switched off
- Heat: operating range 0 to 40 °C, or 0 to 35 °C in portrait; Qatar summers can exceed 45 °C, so confirm cooling and ventilation first

4 files from the manufacturerQuestions about 50UL3J
Is the LG 50UL3J still available from SmartRooms Qatar?
LG has discontinued the 50UL3J, so this exact model may not be available for new orders. SmartRooms Qatar can quote a current equivalent of about 50 inches or a compatible replacement that works with your existing mounts and content software. Send your quantity and site location, and request a quote. We usually respond within one working day.
What is the 50UL3J best suited for?
It suits indoor reception areas, corridors, meeting rooms and lobbies where one 50-inch screen shows information, announcements or wayfinding. Its 3840 x 2160 IPS panel keeps text and images sharp at close viewing distances, and the built-in webOS 6.0 platform plays content without an external media player. For large lecture halls or boardrooms, a bigger panel is usually the better choice.
Will the screen work in a West Bay lobby with windows facing it?
The typical brightness is 400 nit, the contrast ratio is 1,200:1, and the surface haze is 3%. The source data gives no direct sunlight rating, so do not treat this model as suited to direct sunlight. If the screen would face a window in a hotel or office lobby in West Bay, ask the SmartRooms Qatar team to review glare and placement before you order.
What temperatures can the display handle during a Qatari summer?
The operating range is 0 to 40 °C, or 0 to 35 °C in portrait orientation, with operating humidity from 10 to 80 percent. Summer temperatures in Qatar can exceed 45 °C. If a clinic in Al Sadd or Al Rayyan plans to place the screen near a window or in an area without reliable air conditioning, confirm cooling and ventilation before mounting.
Can the 50UL3J run on Qatar's 240 V mains supply?
The built-in power supply is rated for 100 to 240 V at 50/60 Hz, which covers the 240 V, 50 Hz supply used in Qatar. Typical power draw is 105 W and the maximum is 150 W. Smart energy saving reduces the typical figure to 66 W, and power-off draw is 0.5 W. The source data does not list the plug type, so confirm the socket and cable arrangement with the SmartRooms Qatar team when you request a quote.
How do I connect laptops and media players to it?
The display has three HDMI inputs supporting HDCP 2.2 and 1.4, one RJ45 LAN port, two USB 2.0 Type A ports and RS232C in and out for serial control. Built-in Wi-Fi and Bluetooth add wireless options. It has no DisplayPort, DVI-D or RGB inputs, so older equipment that relies on those connections will need an adaptor or a different model.
Can it be controlled by Crestron or Cisco systems in a meeting room in Education City?
Yes. The source data states that the UL3J series supports Crestron Connected for integration with professional AV control systems, and it lists Cisco certification for video conferencing compatibility. Automated control depends on the programming of your own system, so a meeting room in Education City should have its setup reviewed with the SmartRooms Qatar team before installation.
Can a multi-site organisation monitor the display remotely?
Yes. The unit includes a web-based monitoring and control tool that lets authorised users check and adjust the display in real time from a phone or PC on a network, with access to current and past data. The LG ConnectedCare cloud service is available as an optional add-on for remote status checks and fault diagnosis across several sites in Doha and beyond.
Can I mount it in portrait orientation in a school corridor?
Yes, the panel supports both portrait and landscape orientation. In portrait mode, however, the operating range narrows to 0 to 35 °C. In portrait the screen stands about 1121 mm tall, which can suit a narrow corridor wall in an Al Wakrah school or a clinic. Check the wall width and ceiling height during the site survey before fixing the mount.
What should I plan for when wall mounting the display?
Plan for a VESA 200 x 200 mm mounting pattern, an 11.7 kg head weight and a 14.4 kg packed weight, with overall dimensions of 1121 x 651 x 57.1 mm. SmartRooms Qatar offers free site surveys and professional installation, so we can check wall strength, cable routes and mount compatibility before you order, which helps avoid delays on a heavy panel.
Does the screen include speakers and sensors?
Yes. It has two 10W built-in speakers, so announcements and video audio can play without a separate sound system. It also has a temperature sensor and an auto brightness sensor that adjusts the screen to the room light. The specifications do not list proximity, humidity or gyro sensors, so do not plan around them.
Can several units be combined into a video wall?
The data lists a Tile Mode Setting feature for arranging units together, and the bezel is 7.3 mm on three sides when switched off. The specifications do not define a specific tiling layout, so ask SmartRooms Qatar to confirm the configuration for your wall size, including the number of screens, mounts and cabling, before you request a quote for a mall or lobby in Lusail.
