Overview

The LG 50UL3J-N is a 50-inch UHD digital signage display with an IPS panel, built-in Wi-Fi, a built-in speaker and webOS 6.0. The manufacturer has discontinued this model, so this page serves existing owners and buyers looking for a replacement. It suits lobbies, reception areas and corridors in offices, clinics and schools. Request a quote from SmartRooms Qatar for a current equivalent or compatible replacement.

What the 50UL3J-N is built to do

The LG 50UL3J-N is a 50-inch digital signage display from the UL3J series. Its IPS panel delivers 3840x2160 UHD resolution with a viewing angle of 178 degrees horizontally and vertically, so content stays readable for people standing at a reception desk or walking past a corridor wall. The 10-bit colour depth, with 1.07 billion colours, helps menus, wayfinding maps and brand visuals look accurate. Because LG has discontinued this model, the sections below help existing owners judge whether it still fits, and help buyers compare it with current options.

Specifications that matter on site

Typical brightness is 400 nit with a 1,200:1 contrast ratio and a 3% haze surface treatment, which suits indoor areas with controlled lighting. The manufacturer rates the display for 16 hours of operation per day across seven days, with a minimum panel life of 30,000 hours. The power supply is built in and accepts AC 100-240V at 50/60Hz, a range that covers Qatar's 240 V, 50 Hz mains. Typical consumption is 105 W and maximum is 150 W, while smart energy saving mode is rated at 66 W. The unit has no cooling fan.

Connectivity and content management

The display offers three HDMI inputs with HDCP 2.2 and 1.4 support, two USB 2.0 Type A ports, one LAN port, and RS232C input and output for control. Built-in Wi-Fi and webOS 6.0 let you schedule local content, group displays together and share a laptop screen through LG One:Quick Share. The data lists Crestron Connected support, while Cisco certification is shown as to be confirmed, so check that point before specifying the display for a video conference room.

Built-in Wi-Fi with 8GB of internal memory
Temperature and auto-brightness sensors built into the unit
Landscape and portrait orientation for menus and totems
USB plug-in support for external sensors such as temperature sensors

Where it fits in Qatar

A government department in Msheireb could use a display like this in a public service lobby to show queue numbers, service directions and announcements. On-screen menus include Arabic alongside English, which helps teams that work in both languages side by side. A clinic in Al Sadd might run patient information in an air-conditioned waiting corridor, and a hotel or serviced apartment in The Pearl could use portrait mode in a lift lobby. Every one of these locations must be indoors and climate-controlled, because the operating range tops out at 40 °C, and 35 °C in portrait mode.

What to plan before ordering

Check the wall before anything else. The VESA interface is 200 x 200, the head weighs 11.7 kg and the packed weight is 14.4 kg, so the bracket must be rated for that load. The display measures 1121 x 651 x 57.1 mm. Plan cable routes for HDMI, LAN and power, and note that the power supply is built in, so there is no separate power box to mount. A free site survey from SmartRooms Qatar can confirm the wall structure, cable route and power point before installation.

The box includes a remote controller with two batteries, a power cord, a regulation book, a phone-to-D-sub9 cable and a cable holder. Request a quote for a current equivalent or a compatible replacement, and we will confirm options against your wall space and input needs. Quotations are usually returned within one working day, and purchase orders or LPOs are accepted.

Questions about 50UL3J-N

Is the LG 50UL3J-N still available from LG?

No. LG has discontinued the 50UL3J-N, so this page is for owners and buyers who need to compare options. If you already run one, check that its site still fits the 0 °C to 40 °C operating range and the 240 V supply. For a new order, SmartRooms Qatar can quote for a current equivalent or a compatible replacement that matches your wall space, inputs and software needs. Quotations are usually returned within one working day.

Is the 50UL3J-N a good fit for a clinic waiting area or school corridor in Doha?

Yes, provided the space is indoors and air-conditioned. The IPS panel with 3840x2160 resolution and 178-degree viewing angles suits people sitting or walking past at different positions. Waiting areas can show queue numbers, visit instructions and health awareness content in Arabic and English, because the on-screen menus support Arabic. Avoid entrances or exposed walkways where heat is not controlled, since the display is rated only to 40 °C.

How bright is the 50UL3J-N, and can it sit near a window in Doha?

The panel is rated at 400 nit typical brightness, with a 1,200:1 contrast ratio and a 3% haze surface treatment. These figures suit indoor spaces with controlled lighting. Direct sunlight through a window can wash out content, so place the display away from glazing. Heat near an uncontrolled window can also push conditions outside the 0 °C to 40 °C operating range, so assess the location before installation.

Can this display run in an outdoor or unconditioned area during summer?

No. The manufacturer rates operation from 0 °C to 40 °C, and only to 35 °C in portrait mode, with humidity between 10% and 80%. Summer temperatures in Qatar regularly exceed 45 °C, and dust storms can affect exposed equipment. The display should be installed inside an air-conditioned building. If you need an outdoor or semi-outdoor screen, ask SmartRooms Qatar to review the environment before preparing a quotation.

Which inputs and ports are available for connecting a media player or laptop?

The display has three HDMI inputs supporting HDCP 2.2 and 1.4, which suits most HDMI sources. It also has two USB 2.0 Type A ports for plug-in sensors or content, one LAN port, and RS232C input and output for control. There is no DisplayPort, DVI-D, analogue RGB or separate audio input, so check your source device before ordering.

Does it support wireless screen sharing and content distribution for meeting rooms?

Yes. The UL3J series has built-in Wi-Fi, and LG One:Quick Share lets a presenter share a PC screen through the USB transmission unit. Basic settings such as volume and picture mode can be adjusted without the remote. The display can also distribute content and update firmware wirelessly on the same network, and the data lists Screen Share and Play via URL. This helps in meeting rooms where cable routing through finished walls is difficult.

Does it work with Crestron or Cisco video conferencing systems in a West Bay meeting room?

The manufacturer data lists Crestron Connected support, which helps integrate the display with professional AV control. Cisco certification for this model is listed as to be confirmed, so do not assume compatibility with an existing Cisco video conferencing setup. Before choosing this model for a West Bay boardroom, ask SmartRooms Qatar for the current compatibility position so the decision rests on confirmed information.

Which content management software works with this display?

The data lists SuperSign CMS, SuperSign Control and Control+, SuperSign WB, SuperSign Media Editor and Signage 365 Care as compatible. Promota, LG's simple content creation tool, is also listed for this model. Built-in CMS features include local content scheduling, a group manager and Control Manager. Mobile CMS is not listed for this model, so plan your content workflow around the supported platforms.

How much power does it draw, and does it suit Qatar's electrical supply?

The power supply is built in and accepts AC 100-240V at 50/60Hz, so its input range covers Qatar's 240 V, 50 Hz mains. Typical consumption is 105 W and maximum is 150 W, and smart energy saving mode is rated at 66 W. Standby and power-off draw are each 0.5 W. Confirm that the supplied power cord suits your BS 1363 sockets before installation.

What should be planned when mounting this display on a wall in a Lusail office corridor?

The VESA interface is 200 x 200, the head weighs 11.7 kg and the packed weight is 14.4 kg, so the bracket must be rated for that load. The display measures 1121 x 651 x 57.1 mm. Plan cable routes for HDMI, LAN and power in advance. Because the power supply is built in, there is no separate power box to mount. A free site survey from SmartRooms Qatar can confirm wall structure and the power point before any drilling starts.

What accessories come in the box, and can the screen be operated without a remote?

The box includes a remote controller with two batteries, a power cord, a regulation book, a phone-to-D-sub9 cable and a cable holder. Local key operation is limited to power on and off, so the remote is needed for most adjustments. The built-in speaker is listed in the data, so basic audio does not require external speakers, though you should plan the remote's storage in the control room.

Can a government department or school order several units with an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders and LPOs and supports government tenders, including those through Monaqasat. Payment can be made by bank transfer, cheque or purchase order. Products are covered by the manufacturer's warranty. If a school is fitting screens across several classrooms or corridors, ask for one quotation listing each unit, its accessories and the wall-mount plan so the LPO matches the order.
