Brand: LG
SKU: lg-43um3df
Availability: Discontinued

Overview

The LG 43UM3DF is a 43-inch UHD signage display with an IPS panel, 3,840 x 2,160 resolution and 350 nits typical brightness. It adds IP5x dust protection, 30-degree tilt installation, built-in speakers, a removable logo and OPS compatibility for media players. The manufacturer has discontinued this model, so request a quote for a current equivalent or compatible replacement for your Qatar site.

What the 43UM3DF is and who it suits

The LG 43UM3DF is a 43-inch standard signage display from the UM3D series, designed for indoor information screens, menu boards, wayfinding and promotional loops. Its IPS panel runs at 3,840 x 2,160 (UHD) in a 16:9 format and can be mounted in landscape or portrait. The manufacturer has discontinued this model, so this page is written for organisations that already run it, buyers comparing it with newer displays, and anyone who needs a like-for-like replacement.

Picture quality, brightness and content handling

With 350 nits typical brightness, a 1,100:1 contrast ratio, a 178 x 178 viewing angle and an 8 ms (G to G) response time, the panel keeps content readable from the side of a corridor or a reception desk. The manufacturer states support for HEVC, which it says plays UHD video with half the network traffic of H.264. A built-in quad-core processor runs playlists without a separate media player, and OPS compatibility lets you add one when a project needs it.

Installation planning: weight, tilt and bezel

The head weighs 11.2 kg and the packed unit 13.7 kg, in a carton measuring 1,060 x 660 x 152 mm, so plan for two people to handle it and confirm that any wall or bracket is rated for the load. The VESA interface is 200 x 200. The bezel measures 8.4 mm on the top, left and right and 14.4 mm at the bottom, and the depth is 39.9 mm. A 30 degree tilt is supported under conditions of 30°C and 50% humidity, while the horizontal sensor and automatic orientation detection help with precise levelling. The optional ST-653T stand, LSW240B wall bracket and AM-B220S VESA adapter are listed for this model.

Connectivity, software and running it in Qatar

Inputs cover three HDMI ports, DisplayPort, DVI-D, USB 2.0 and audio, with a DisplayPort output. External control comes through RS232C in and out, an RJ45 LAN port and an IR input. The screen can send email notifications when a problem such as tilting from an external impact is detected. Software listed for the model includes SuperSign CMS, SuperSign Control and Control+, and Signage365Care. Power input is 100-240 V at 50/60 Hz, with typical draw of 70 W and maximum of 105 W. The operating range is 0°C to 40°C, so in Qatar, where outdoor summer heat can pass 45°C, install it in air-conditioned rooms rather than shaded outdoor or unconditioned spaces, and confirm the environment with the SmartRooms Qatar team before installation.

Where it fits in Qatar

A university in Education City placing wayfinding screens in corridors and atriums inside air-conditioned buildings.
A hotel lobby in West Bay showing event schedules, with the screen set in portrait beside the lift lobby.
A clinic in Al Sadd using a wall-mounted screen in the waiting area to show queue and health information.

Every project should start with a free site survey to check wall loading, sightlines, sun exposure and cable routes. Government and school buyers can issue an LPO or reference a tender, and quotations are usually provided within one working day. Request a quote and our team will recommend a current equivalent or compatible replacement for your 43-inch signage project in Qatar.

Questions about 43UM3DF

Is the LG 43UM3DF still available from the manufacturer?

LG has discontinued the 43UM3DF, so new units may not be available from the manufacturer. SmartRooms Qatar can quote a current equivalent or a compatible replacement that matches your project requirements. Quotations are usually provided within one working day, and we will confirm the closest match to the size, resolution and mounting you need.

Would this display suit a hotel lobby in West Bay?

Yes, the 43-inch size and 3,840 x 2,160 resolution suit a hotel lobby showing event schedules, restaurant times or wayfinding. Its 350 nits typical brightness works well in indoor lighting. A hotel can place it in portrait beside the lift lobby, where the auto-detected orientation means the on-screen menu is already set when first powered on.

Can the screen be used in portrait orientation?

Yes. The display supports portrait and landscape orientation and detects its orientation automatically during the initial setup, so the on-screen menu and background content are already correct when you first switch it on. This is useful for menu boards, directory signs and narrow corridors in shopping malls, where a tall layout reads better than a wide one.

Is its brightness enough for a bank branch in Msheireb near windows?

Typical brightness is 350 nits with a 1,100:1 contrast ratio, which suits indoor branch areas with ordinary lighting. If the screen sits near windows facing the sun, mount it away from direct sunlight and test the view during the free site survey. Glare control is a placement decision, so plan the position before the wall is prepared.

Can it run in an unconditioned corridor during a Doha summer?

The operating range is 0°C to 40°C with 10% to 80% humidity. Outdoor temperatures in Qatar can exceed 45°C in summer, so the display should be installed in an air-conditioned corridor, not on a veranda, in a sun-exposed lobby or in an unconditioned store. Confirm the exact environment with the SmartRooms Qatar team before ordering.

Is it suitable for a dusty industrial site in Mesaieed?

The display carries an IP5x rating, which the manufacturer describes as dust-proof protection, so it suits dust-prone areas better than an unprotected screen. IP5x is not a water rating, however, so keep it away from spray, washdown areas and high humidity. A site survey at Mesaieed can confirm the enclosure location and cable routing before installation.

What inputs and connections does it offer?

Inputs include three HDMI ports, one DisplayPort, one DVI-D, USB 2.0 and an audio input, with a DisplayPort output. External control is handled through RS232C in and out, an RJ45 LAN port and an IR input. These connections let facilities teams connect players, networks and control systems without adding separate adapters for most standard setups.

Can I add an external media player to it?

Yes. The model is listed as OPS compatible, so you can fit an OPS media player if your project needs content run from a slot-in computer module. The OPS kit KT-OPSF is listed as an optional accessory for this model. Tell us which media player you plan to use so we can check the setup in your quotation.

Which software manages the content and monitoring?

The source data lists SuperSign CMS for content management, SuperSign Control and Control+ for control and monitoring, and Signage365Care. These tools suit organisations managing several screens across campuses or branches, such as a school group or a bank with multiple locations, where central scheduling and remote monitoring save site visits.

How much power does it use and will it work on Qatar mains?

Power input is 100-240 V at 50/60 Hz with built-in power, which covers the 240 V supply used in Qatar. Typical consumption is 70 W and maximum is 105 W, and energy-saving mode reduces draw to 50 W. Request a quote for a project with several units so we can estimate the total load for your electrical distribution board.

Can it be wall-mounted on classroom walls at a school in Al Wakrah?

The head weighs 11.2 kg and 13.7 kg packed, with a VESA interface of 200 x 200. It supports a 30 degree tilt under 30°C and 50% humidity conditions. For a school in Al Wakrah mounting several units, a free site survey confirms wall construction, fixing points and sightlines, and an LPO can cover the order. The optional LSW240B wall bracket is listed for this model.

Does it work with Cisco video conferencing and Crestron control systems?

The manufacturer states that this model is certified for compatibility with Cisco systems, offering integrated control for video conferencing, and it is Crestron Connected certified for AV control. Before ordering, confirm your exact Cisco or Crestron setup and meeting room layout with the SmartRooms Qatar team so the integration matches your environment.
