Overview

The LG 49UM3F is a 49-inch UHD signage display with 350 nits typical brightness, an IPS panel and 3,840 x 2,160 resolution, suited to indoor reception areas, corridors and information points. It accepts OPS media player modules and runs in portrait or landscape. The manufacturer has discontinued this model, so request a quote for a current equivalent or compatible replacement.

What the LG 49UM3F is designed to do

The LG 49UM3F is a 49-inch UHD signage display from the UM3F series, built for showing menus, wayfinding, announcements and promotional video in indoor public areas. Its IPS panel resolves 3,840 x 2,160 pixels, which is four times the detail of Full HD, so schedules, small text and product imagery stay legible at close range. Typical brightness is 350 nits, and the panel is rated for 24-hour operation with a typical life of 50,000 hours.

The specifications that shape the buying decision

The display is rated for operating temperatures from 0°C to 40°C and humidity from 10% to 80%, which means it belongs in air-conditioned indoor rooms. Its 100-240V, 50/60Hz built-in power supply covers the 240V, 50Hz mains used across Qatar. Typical power draw is 85W, with a maximum of 120W and a smart energy saving figure of 65W. The monitor measures 1,098.6 mm x 644.5 mm x 39.9 mm and weighs 15.4 kg without packaging, so the wall or ceiling structure should be checked before installation.

Where it fits in Qatar

A hotel lobby in West Bay: a landscape display behind the front desk shows check-in information, event listings and airport transfer times. The 350 nits typical brightness suits a room with ceiling lighting, but a window-facing position needs the screen placed out of direct sun.
A clinic waiting area in Al Sadd: a portrait display in a corridor shows queue numbers and department directions, with content arranged in whichever languages the clinic uses.
A government office reception in Msheireb: a wall-mounted display beside the lift lobby, managed remotely or through RS232C from the building control system, shows visitor information and service updates.

Content, control and connectivity

Connections include three HDMI inputs, a DisplayPort input, DVI-D, USB 2.0 and an audio input, plus a DisplayPort output and audio output. External control is handled through RS232C in and out, an RJ45 LAN port and an IR input. The built-in quad-core processor plays content without a separate media player, and LG webOS runs the signage interface. Supported content management software includes SuperSign CMS, with SuperSign Control and Control+ for monitoring, and Signage365Care is listed as supported. The UM3F series supports HEVC, which the manufacturer says plays UHD video with half the network traffic of H.264. It is certified as Crestron Connected and certified for compatibility with Cisco video conferencing systems.

Planning the installation

Mounting: the VESA pattern is 300 x 300. Optional accessories include the wall bracket LSW350B, the VESA adapter AM-B330S and the ST-653T stand.
Tilt: the display supports up to 30 degrees of downward tilt, a figure the manufacturer gives for conditions within 30°C and 50% humidity.
Orientation: it detects portrait or landscape at first start-up, and a horizontal sensor helps level the panel during fitting.
Bezel: 9.9 mm on the top, left and right, and 14.4 mm at the bottom, which matters if you plan a multi-panel layout.
Protection: an IP5x rating covers dust ingress, which helps in dusty indoor areas, though it is not an outdoor rating.

SmartRooms Qatar offers free site surveys before wall mounting, so the installation team can check the structure, power point and viewing height for the 15.4 kg display. Basic accessories include a remote controller, power cord, quick start guide, HDMI cable, regulation book and a phone-to-RS232C gender adapter.

Questions about 49UM3F

Is the LG 49UM3F still available from SmartRooms Qatar?

LG has discontinued the 49UM3F, including its 49UM3F-B variant, so new orders for this exact model may not be possible. SmartRooms Qatar can quote a current equivalent or a compatible replacement based on your required size, resolution and mounting setup. If you already own a 49UM3F and need a matching spare, send the model code and quantity with your enquiry so the team can advise on the closest option before you request a quote.

What is the LG 49UM3F designed for?

The 49UM3F is a 49-inch UHD signage display for indoor public areas where information needs to be clear at close range, such as reception desks, corridors, lift lobbies and waiting rooms. Its 3,840 x 2,160 IPS panel gives four times the pixel count of Full HD, and the display is rated for 24-hour operation. It suits organisations that need a dependable screen to show schedules, wayfinding and announcements every day.

Does the 49UM3F support HEVC video and how does that affect network load?

Yes. The UM3F series supports HEVC, the High Efficiency Video Coding standard. LG states that HEVC plays UHD content with half the network traffic of the H.264 codec. In a building where several displays draw from a central content server, this can reduce the bandwidth needed to stream high-resolution loops. Confirm your network plan with your IT team before deployment, as actual traffic depends on your content and encoding settings.

Is 350 nits bright enough for a lobby with windows in Doha?

The 350 nits figure is a typical brightness rating, which suits indoor areas under ceiling lighting rather than direct sunlight. In a West Bay hotel lobby or a Lusail office with floor-to-ceiling glass, position the screen away from the glass so that sun does not wash out the image. Summer sun in Doha is intense, so avoid a spot that receives direct afternoon light, and confirm the lighting level during your site survey.

Can I run signage content without a separate media player?

Yes. The display has a built-in quad-core processor that plays content without an external media player, and it runs LG webOS. Content can be managed with SuperSign CMS, and SuperSign Control or Control+ handles monitoring. If you prefer a separate player, the model is listed as OPS Type compatible, and the OPS Kit (KT-OPSF) and a media player are optional accessories you can add to the quotation.

Can the 49UM3F be mounted in portrait for a directory or corridor?

Yes. The panel supports portrait and landscape orientation and detects its orientation during the first start-up, so you do not need to set rotation manually. A portrait-mounted unit suits a directory beside a lift lobby in Lusail or a floor sign in a hospital in Doha, where vertical content such as floor lists and room numbers reads well. Check the mounting bracket and wall space during the survey, because the mount must hold the display securely in portrait position.

Which mounting parts do I need for a wall installation?

The monitor uses a 300 x 300 VESA mounting interface. The wall bracket LSW350B is listed as an optional accessory, along with the VESA adapter AM-B330S for compatible mounts and the ST-653T stand for freestanding use. The display weighs 15.4 kg without packaging, and its packed weight is 18.8 kg. A free site survey from SmartRooms Qatar can confirm the wall or column is suitable before the bracket is fixed.

How much power does the 49UM3F use and does it suit Qatar mains?

The built-in power supply is rated 100-240V at 50/60Hz, a range that includes the 240V, 50Hz mains supply used in Qatar. Typical consumption is 85W, with a maximum of 120W, and the smart energy saving mode is listed at 65W. For a school or office fitting out several units, these figures help estimate the load on each circuit. Your electrical contractor should confirm socket and circuit arrangements during installation planning.

Can it be installed in a hot area such as a loading bay or outdoor canopy?

No. The operating temperature range is 0°C to 40°C, with humidity from 10% to 80%, so the 49UM3F is intended for air-conditioned indoor rooms. Qatar summer temperatures can exceed 45°C, which makes a loading bay, an open canopy or a shaded outdoor walkway in Mesaieed or the Industrial Area unsuitable. Confirm the room's air conditioning capacity and conditions with the SmartRooms Qatar team before ordering.

Does it work with video conferencing and AV control systems?

The UM3F series is certified as Crestron Connected for AV control compatibility, and it has certified compatibility with Cisco systems for video conferencing. In a West Bay boardroom where teams join calls with colleagues abroad, this reduces the time spent adjusting picture settings or switching inputs when an incoming call arrives. Your AV integrator should confirm the exact control protocol and system version during design.

How will we know if a display has a problem when it is at a remote branch?

The display can send email notifications when a problem occurs, such as the unit being tilted by an external impact, so staff can act quickly. Signage365Care is listed as supported, and SuperSign Control and Control+ provide monitoring. For a hotel in West Bay or a facilities team managing several sites across Doha, this means faults can be spotted without visiting every location. Confirm the notification setup and network requirements with your IT team.

Can a school order several units under one purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, so a school or education group in Al Wakrah or Education City can request one quotation covering several units. Payment is accepted by bank transfer, cheque or purchase order. Because this model is discontinued, ask for a current equivalent in the same quotation so that all units match.
