Overview

The LG 49UM3DF is a 49-inch digital signage display with a 3,840 x 2,160 IPS panel, 350 cd/m² typical brightness, portrait and landscape orientation and IP5x dust protection. LG has discontinued this model, so organisations in Qatar that already run it, or need a like-for-like replacement for lobbies, corridors and meeting areas, should request a quote for a current equivalent.

A 49-inch UHD display for indoor information points

The LG 49UM3DF is a 49-inch digital signage display with a 3,840 x 2,160 IPS panel. Its resolution is four times that of Full HD, so small text and fine graphics stay crisp at close viewing distances. The manufacturer has discontinued this model, so this page is written for organisations that already own it, buyers comparing it with newer displays, and anyone who needs a like-for-like replacement in Qatar.

Panel performance that matters on site

The panel has a typical brightness of 350 cd/m² and a contrast ratio of 1,100:1. The IPS technology keeps colour and contrast consistent at wide angles, with a stated viewing angle of 178 degrees both horizontally and vertically. An 8 ms grey-to-grey response time suits moving menus and looping video. The surface has 3% haze, which reduces reflections. The typical panel life is 50,000 hours, and the specification lists 18 hours of operation.

Installation, mounting and space planning

The monitor measures 1,098.6 mm wide, 644.5 mm high and 39.9 mm deep, with a head weight of 15.4 kg. Side and top bezels are 9.9 mm and the bottom bezel is 14.4 mm, which helps multi-screen rows look tidy. The VESA pattern is 300 x 300 mm. The panel works in portrait and landscape, and it detects its orientation automatically during first setup. A tilt of up to 30 degrees is supported under stated conditions of 30°C and 50% humidity.

Check that the wall or ceiling can carry the head weight before ordering.
Plan cable routing for power, video and LAN before the day of installation.

SmartRooms Qatar offers free site surveys before wall-mounting a panel of this size. Optional accessories include the ST-653T stand, the LSW350B wall bracket and the AM-B330S VESA adapter.

Where it fits in Qatar

At a bank branch in West Bay, a panel of this size can sit near the queue to show service information without staff updating printed boards. In a government office in Msheireb or the Industrial Area, it suits floor directories and internal notices in Arabic and English. In an education centre or school in Education City, it works well for timetables and campus announcements.

The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so install the display indoors in an air-conditioned room, away from direct sunlight and window glare. Confirm room conditions with the SmartRooms Qatar team before mounting near windows or open entrances.

Software, connections and monitoring

The panel offers three HDMI inputs, a DisplayPort input, DVI-D, audio and USB 2.0, with DisplayPort and audio outputs. External control is available through RS232C in and out, an RJ45 LAN port and an IR input. Its quad-core processor and webOS platform can play content without a separate player, and it is compatible with OPS-type media players. It supports SuperSign CMS, SuperSign Control and Control+, and Signage365Care. The model is certified for Crestron Connected and for compatibility with Cisco systems. If the panel is tilted by an external impact, it can send an email alert, which helps facilities teams respond quickly.

Questions about 49UM3DF

Is the LG 49UM3DF still available from SmartRooms Qatar?

LG has discontinued the 49UM3DF, so this page is for buyers who already own it or need a replacement. SmartRooms Qatar can quote for a current equivalent or a compatible replacement that matches your screen size, mounting and software needs. Send us the model code and site requirements, and the quotation will show the closest option and any differences in specification.

Who is this 49-inch display best suited to?

It suits indoor information points where text needs to stay sharp at close range, such as a bank branch in West Bay, a clinic waiting area in Al Rayyan or an office reception in Msheireb. The 3,840 x 2,160 IPS panel and 350 cd/m² typical brightness suit rooms with ordinary indoor lighting rather than direct sunlight. Large lobbies with strong daylight should be reviewed during the site survey.

Can it operate in Qatar's summer heat?

The stated operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so install the display indoors in an air-conditioned room, away from direct sunlight and window glare. Confirm room conditions with the SmartRooms Qatar team before mounting near windows or open entrances. The IP5x rating covers dust protection only.

Does it need a separate media player?

The panel is listed as compatible with OPS-type media players, and LG lists an OPS Kit (KT-OPSF) and a media player as optional accessories. It also has a built-in quad-core processor with webOS for playing content. The software compatibility list includes SuperSign CMS, SuperSign Control and Control+, and Signage365Care. Confirm the setup with the quotation so that it matches your content workflow.

Which inputs and control ports does it have?

Inputs are three HDMI ports, one DisplayPort, DVI-D, audio and USB 2.0. Outputs are DisplayPort and audio. External control uses RS232C in and out, an RJ45 LAN port and an IR input. Facilities teams can control several panels over RS232C or manage them across the network. Map these ports against your cable plan during the site survey.

Is it compatible with Crestron and Cisco systems?

Yes. The product is certified as Crestron Connected for professional AV control, and it is certified for compatibility with Cisco systems. For a government meeting room in Doha using Cisco video conferencing, the source data states that the panel avoids manual picture setup when incoming calls arrive. Confirm the exact controller and Cisco versions in your room design before ordering.

Can it be mounted in portrait orientation or tilted?

Yes. The panel supports portrait and landscape, detects its orientation during first setup, and uses a 300 x 300 mm VESA pattern. A tilt of up to 30 degrees is supported under stated conditions of 30°C and 50% humidity. A horizontal sensor helps align the panel. SmartRooms Qatar's free site survey can confirm wall loading for a 15.4 kg head before installation.

What wall space and clearance does it need?

The monitor measures 1,098.6 mm wide, 644.5 mm high and 39.9 mm deep, with a head weight of 15.4 kg and a packed weight of 18.8 kg. Plan a mounting area that fits these dimensions, with room for cables behind the panel. The optional LSW350B wall bracket and ST-653T stand can support different layouts, and the survey will confirm which suits your wall.

Will it send an alert if someone moves or knocks it?

Yes. The source data states that the panel can email notifications when a problem occurs, such as tilting caused by an external impact. In a hotel lobby in Lusail or a school entrance, this lets facilities staff respond quickly. Set up the mail settings with your network team during installation, and make sure the LAN port is connected to a network that can send email.

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

Typical consumption is 85W, with a maximum of 120W and 65W in smart energy saving mode. The power supply is rated 100-240V at 50/60Hz, which covers Qatar's 240 V, 50 Hz mains supply. The basic kit includes a power cord. The ErP label applies to EU only, and the product is rated Energy Star 8.0. Confirm the cord and socket arrangement in your quotation.

Can a government entity order this display through an LPO or tender?

Yes. SmartRooms Qatar supports LPOs and government tenders, including Monaqasat, and accepts payment by bank transfer, cheque or purchase order. A ministry ordering several 49-inch displays for public waiting areas can request a quotation that lists the specification of each unit. The products are covered by the manufacturer's warranty.

What should I send if I already run this model and need more units?

Send the model code, the number of units you need, the mounting method and the content software you use, such as SuperSign CMS or another platform. We will quote matching units or a compatible replacement and check the wall, power and cable layout against the site survey. This keeps new displays consistent with the ones already installed in your building.
