LG 65UM3F (Discontinued) · Replacements in Qatar

Name: LG 65UM3F 65-inch 350-nit UHD Digital Signage Display
Brand: LG
SKU: lg-65um3f
Availability: Discontinued

Overview

The LG 65UM3F is a 65-inch UHD signage display with an IPS panel, 350 nits typical brightness and IP5x dust protection, built for indoor lobbies, corridors and meeting areas. It accepts three HDMI inputs plus DisplayPort and DVI-D, runs in portrait or landscape, and includes built-in speakers. The manufacturer has discontinued this model, so Qatar buyers who need it or a comparable replacement should request a quote.

What the LG 65UM3F is built for

The LG 65UM3F is a 65-inch signage display from the UM3F series, made for indoor locations where visitors, staff and customers need information quickly. Its IPS panel offers a native resolution of 3,840 x 2,160, four times the pixel count of Full HD, so menus, maps and fine text stay crisp when people stand close to the screen. Typical brightness is 350 cd/m², and viewing angles reach 178 degrees horizontally and vertically, so content stays readable from the side of a busy lobby.

The manufacturer lists a 1,100:1 contrast ratio, an 8ms grey-to-grey response time, a 3% haze surface treatment and a typical life of 50,000 hours, with the display rated for 24-hour operation. Because this model is discontinued, those figures are most useful when you compare it with a current equivalent.

Connectivity, control and software

Three HDMI inputs, a DisplayPort input and output, a DVI-D input, audio input and output, and a USB 2.0 port cover the sources most Qatari offices and schools connect. For remote management, the display provides RS232C in and out, an RJ45 LAN port and an IR input. A single joystick handles power, input selection and volume, instead of the many buttons found on older models. The built-in quad-core processor and webOS platform can play content without an external media player, and the display is OPS-compatible for slot-in players.

For content, the software list includes SuperSign CMS for management, SuperSign Control and Control+ for monitoring, and Signage365Care support. The model is certified Crestron Connected for AV control integration and certified for compatibility with Cisco systems, which helps meeting rooms that rely on Cisco video calls.

Where it fits in Qatar

Lobby wayfinding: a government authority in West Bay placing a portrait-mounted screen beside its reception desk to show service queues and directions.
School corridors: a private school in Al Wakrah placing screens outside classrooms to show timetables and events, with content updated from one office.
Clinic waiting areas: a clinic in Msheireb displaying appointment information in air-conditioned waiting rooms.

Planning the installation

The head measures 1,453.3 mm wide, 844 mm high and 39.9 mm deep, and weighs 28.2 kg (35.0 kg packed). The bezel is 9.9 mm on the sides and top and 14.4 mm at the bottom, and the VESA pattern is 300 x 300. Confirm the wall or column can carry the load and plan for at least two people to lift the unit. Power is 100-240V, 50/60Hz with built-in power, drawing a typical 110W and a maximum of 160W, with a smart energy saving mode at 85W.

Heat and dust need care. The operating range is 0°C to 40°C and 10% to 80% humidity. Qatar summer temperatures exceed 45°C outdoors, so install the display only in air-conditioned rooms, away from unconditioned entrances and open courtyards. The IP5x rating covers dust, but the data does not list water resistance, so keep the display indoors. Face-down tilt of up to 30 degrees is specified only within 30°C and 50% humidity, so check a high mount on site.

If you already own this model

LG has discontinued the 65UM3F. If your organisation already runs units, keep the remote, quick start guide and regulation book with the asset record, and confirm stands, brackets and OPS kits before buying more, as discontinued accessories may be hard to source. For a new project, ask for a quote on a current equivalent that matches your size, resolution and mounting pattern.

Questions about 65UM3F

Is the LG 65UM3F still sold, and what should I order instead?

LG has discontinued the 65UM3F, so it is no longer in the manufacturer's current range. SmartRooms Qatar can quote for a current equivalent or a compatible replacement that matches your 65-inch size, indoor use and 300 x 300 mounting pattern. Tell us the number of screens, the room and whether you need an OPS slot, and we will confirm the best match in your quotation.

What is the LG 65UM3F built for?

It is a 65-inch UHD signage display for indoor locations where people need information quickly, such as lobbies, corridors and meeting areas. The IPS panel's 3,840 x 2,160 resolution keeps menus and small text sharp at close range, and the 350 cd/m² typical brightness suits rooms lit by ceiling lights. It can run in portrait or landscape, so it works for wayfinding columns as well as wide notice boards.

How bright is the panel for a sunlit entrance in Doha?

Typical brightness is 350 cd/m², which suits indoor rooms with artificial light. The data does not rate this model for direct sunlight, so a position facing a glass atrium or a window in Doha's strong daytime sun needs a site check first. Our free site survey reviews the mounting position and recommends either a different location or a current high-brightness model.

What operating temperature does it need in a Qatar summer?

The manufacturer specifies operation from 0°C to 40°C and 10% to 80% humidity. Qatar summer temperatures exceed 45°C outdoors, so install the display only in air-conditioned rooms, away from unconditioned entrances, covered outdoor areas and kiosks without climate control. Ask our team to confirm that the room's cooling keeps the space within that range before mounting.

Can it be tilted downward for a high-level mount?

The manufacturer supports tilting the display face-down by up to 30 degrees, but states that figure applies within 30°C and 50% humidity. For a high mount in a lobby or atrium, the tilt angle should be checked against the room's conditions during the site survey. The horizontal sensor on the display helps the installer set the angle precisely.

How much does it weigh, and what should I plan for when mounting it?

The head weighs 28.2 kg and the packed unit weighs 35.0 kg. The panel measures 1,453.3 mm wide, 844 mm high and 39.9 mm deep, with a 300 x 300 VESA pattern. Confirm the wall or column can take the load, check the clearance around the mount, and plan for at least two people to lift the unit. Our free site survey covers these points before installation.

Which mounting and stand options are available?

The basic package includes a remote controller, power cord, quick start guide, HDMI cable, regulation book and a phone-to-RS232C gender adapter. Optional items listed for this model are the ST-653T stand, the LSW350B wall bracket, the AM-B330S VESA adapter and the KT-OPSF OPS kit. Check that any bracket matches the 300 x 300 pattern and the 28.2 kg head weight before ordering.

Does it need an external media player?

The manufacturer states that the built-in quad-core processor and webOS platform play content without a separate media player. The display is also OPS-compatible, so an OPS-type player can be added through the optional KT-OPSF OPS kit if your setup requires one. Tell us which content and software you plan to run so we can recommend the right configuration in your quotation.

What software manages content on the screen?

The software list includes SuperSign CMS for content management and SuperSign Control or Control+ for monitoring and control. Signage365Care is also listed as supported. A private school in Al Wakrah updating timetables and event notices from one office could publish to several screens through the content manager, while the control software shows the status of each display.

Does it work with video conferencing and AV control systems?

Yes. The manufacturer reports certified compatibility with Cisco systems for integrated control, and Crestron Connected certification for professional AV control. That suits a government office or company boardroom that must integrate with an existing control system. Confirm your exact Cisco or Crestron setup with the SmartRooms Qatar team before ordering, because integration depends on your system.

Does it have built-in speakers for announcements?

Yes. The display includes built-in speakers, so a lobby or training room can play announcements and content audio without buying separate speakers. Audio output can be set to off, fixed or variable, and an audio input is also provided. For a large open area in a Lusail shopping mall, check the sound level against the space during the site survey.

Can staff be alerted if it is knocked or tilted?

Yes. The remote monitoring feature can email notifications when a problem occurs, such as the product being tilted by an external impact, so staff can respond quickly. At a hospital entrance in Doha or a busy clinic, that alert lets the facilities team check a display that has moved or been hit, without waiting for a visitor to report it.
