What the LG 65UL3J is built for

The LG 65UL3J is a 65-inch standard signage display from the UL3J series, designed to run information, menus, wayfinding and promotional content for long daily hours in public-facing spaces. Its 3840 x 2160 UHD IPS panel uses a 16:9 aspect ratio and can be set to landscape or portrait, which suits digital menus, corridor columns and narrow reception walls.

The built-in webOS 6.0 platform lets you schedule content on the unit itself, so a separate media player is not always needed.

Picture quality, brightness and running hours

The panel is rated at 400 nit typical brightness, with a 1,200:1 contrast ratio, a 1,000,000:1 dynamic contrast figure, 1.07 billion displayable colours and a DCI 80% colour gamut. For content such as product photography, property renders or school artwork, that combination keeps colours and detail clear across a reception lobby. The 178 degree horizontal and vertical viewing angles help people standing to the side still read the screen.

The 8 ms grey-to-grey response time and 60 Hz refresh rate suit video clips and scrolling text. The data sheet rates operation at 16 hours a day, seven days a week, with a minimum panel life of 30,000 hours, which is the figure to compare against your planned daily running time.

Connectivity, software and control

Inputs: three HDMI inputs with HDCP 2.2 and 1.4 support, one RJ45 LAN input and two USB 2.0 Type A ports.
Control: RS232C input and output for system integration, plus SNMP and Wake on LAN support.
Wireless: built-in Wi-Fi and Bluetooth, with PC screen sharing through the LG One:Quick Share solution.
Software: webOS 6.0 with 8GB internal memory, local content scheduling, play via URL, and SuperSign CMS compatibility.
AV and conferencing: Crestron Connected support and Cisco certification for control and video meeting setups.
Sensors and monitoring: an auto brightness sensor and temperature sensor, plus optional LG ConnectedCare remote monitoring.

Where it fits in Qatar

A hotel lobby in West Bay might use the panel as a welcome and events board, where the 65-inch size is readable from the front desk without dominating the wall. A government ministry reception in Msheireb could use it for visitor directions and service information in Arabic and English, since the on-screen menu supports Arabic. A private school in Al Wakrah fitting out new corridors could mount several units for timetables and announcements, and a clinic waiting area in Al Rayyan could show queue and health-awareness content.

Qatar heat is the main environmental check. The rated operating range is 0 °C to 40 °C, dropping to 35 °C in portrait orientation, with 10 to 80 percent humidity. Summer outdoor temperatures above 45 °C mean the screen should sit in air-conditioned indoor areas, and sunlit atriums, window-facing walls or loading bays need a check with the SmartRooms Qatar team before the quotation is confirmed.

Planning the installation and requesting a quote

Head weight of 21.5 kg and packed weight of 27.5 kg, so plan lifting equipment and two people for the install.
VESA 300 x 300 mm mounting interface; confirm the wall, column or bracket matches it.
Monitor dimensions of 1454 x 838 x 57.7 mm and a carton of 1600 x 970 x 172 mm for storage and delivery access.
Typical power draw of 130 W, maximum 187 W, and 0.5 W in power-off mode, for circuit planning.

SmartRooms Qatar offers a free site survey before wall mounting, so the fixing point, cable route and power position are confirmed first. Quotations are usually returned within one working day. Share your room measurements and content plan, and request a quote for the LG 65UL3J today.

Questions about 65UL3J

What is the LG 65UL3J used for?

The LG 65UL3J is a 65-inch UHD standard signage display for showing menus, wayfinding, announcements and promotional content in public-facing areas. It suits corporate reception areas, corridors, retail floors and waiting rooms where one screen runs for many hours each day. Its built-in webOS 6.0 platform lets you schedule content on the unit itself, so a separate media player is not always needed.

Can the 65UL3J be used in Qatar's summer heat or sunlit areas?

Its rated operating temperature is 0 °C to 40 °C, or 0 °C to 35 °C in portrait orientation, with 10 to 80 percent humidity. Qatar summer temperatures can exceed 45 °C, so keep the screen in air-conditioned indoor spaces. Sunlit atriums, window-facing walls and loading bays should be checked with the SmartRooms Qatar team before the quotation is confirmed.

How bright is the screen and will it be readable in a bright lobby?

The panel is rated at 400 nit typical brightness with a 1,200:1 contrast ratio and 1,000,000:1 dynamic contrast. Its IPS panel offers 178 degree horizontal and vertical viewing angles, so people standing to the side can still read the content. In a lobby with large glass frontage, confirm the sun angle during a site survey before choosing the wall position.

Does the on-screen menu support Arabic?

Yes. The on-screen display language list includes Arabic alongside English, French, German, Spanish, Chinese, Japanese and others. Government offices and schools that work in Arabic and English side by side can set the menu language to suit their staff. Content language depends on the files you publish, so check a sample Arabic file on the unit before the final order.

What inputs and outputs does the 65UL3J have?

It has three HDMI inputs supporting HDCP 2.2 and 1.4, one RJ45 LAN input, two USB 2.0 Type A ports, and RS232C input and output. Audio Out is listed, but there is no HDMI output, so the screen cannot pass its signal to a second display. Daisy chaining is not supported, so plan a separate source for each screen.

Does it have Wi-Fi and wireless screen sharing?

Yes, the 65UL3J includes built-in Wi-Fi and Bluetooth. LG's One:Quick Share solution lets a presenter share a PC screen through a USB transmission unit and its app, and volume and picture mode can be adjusted without the remote. The Office Meeting Mode can display an agenda before a meeting starts.

Will it integrate with our video conferencing and AV control system?

The UL3J series carries Cisco certification and supports compatibility with Cisco solutions for integrated control in meeting rooms. It also supports Crestron Connected for professional AV control and automation. For a boardroom in Doha or a training room in Education City, confirm your control platform and room layout with the SmartRooms Qatar team before requesting the quote.

Can it be wall-mounted, and what should we plan for?

Yes, the unit has a 300 x 300 mm VESA mounting interface. The head weighs 21.5 kg and the packed weight is 27.5 kg, so plan lifting help and check the wall or bracket capacity. The monitor measures 1454 x 838 x 57.7 mm. SmartRooms Qatar provides free site surveys before installation, which confirms the fixing point, cable route and power position.

Does the power supply suit Qatar's electrical network?

The data sheet lists AC 100 to 240 V at 50/60 Hz with a built-in power supply, which covers the 240 V, 50 Hz mains used in Qatar. Typical consumption is 130 W, maximum 187 W, and standby 0.5 W. Confirm the plug type supplied with the unit against your BS 1363 sockets, and have a qualified electrician check the circuit before installation.

Is it suitable for a school corridor or campus information point?

Yes, for corridor and common-area use, a 65-inch panel can show timetables, announcements and campus information clearly. The unit is not a touch display, as the data lists no touch USB input, so students cannot interact with the screen directly. For a school in Al Wakrah or a campus in Education City ordering several units, a purchase order can be raised with SmartRooms Qatar.

Can a central team manage several screens across sites?

The unit supports a web-based remote monitoring solution that lets authorised users check status and make adjustments from a mobile phone or PC. It also supports SuperSign CMS, and the optional LG ConnectedCare cloud service is listed for remote status checks and fault diagnosis. For a hotel group in West Bay managing lobby screens, these tools can help a team check screens without visiting each site.

How do we request a quote and what does SmartRooms Qatar cover?

Send your room details and intended use, and SmartRooms Qatar will usually return a quotation within one working day. We deliver the 65UL3J to all eight municipalities of Qatar, arrange professional installation, and accept purchase orders, government tenders through Monaqasat, and payment by bank transfer, cheque or purchase order. The product is covered by the manufacturer's warranty.
