What the LG 49UM3DG is built for

The LG 49UM3DG belongs to the UM3D line of standard signage displays designed for indoor environments. It combines a 49-inch IPS panel at 3,840 x 2,160 resolution with a slim cabinet and narrow bezels, so it can work alone as an information screen or join others in a video wall. The model code also appears as 49UM3DG-B in manufacturer listings.

Picture quality that holds up at close range

Ultra HD carries four times the pixels of Full HD, so menus, floor plans and product imagery stay crisp when visitors stand close. The IPS panel keeps colour consistent across a 178 x 178 degree viewing angle, which helps people approaching from the side of a corridor. Typical brightness is 350 nits and the contrast ratio is 1,200:1. The panel covers 95% of the BT.709 colour gamut at 10-bit colour depth, and a 3% haze surface treatment limits reflections. The unit also supports HEVC video, which the manufacturer rates at half the network traffic of H.264 for comparable content.

Rated for 18 hours of operation per day
Portrait and landscape orientation, detected automatically at first start-up
Built-in speaker, so basic audio needs no external speakers
Typical power draw 85 W, maximum 120 W

Installation planning for Qatar sites

The head weighs 15.4 kg and mounts on a 300 x 300 VESA pattern, with overall dimensions of 1,098.6 x 633.3 x 39.9 mm. Check the wall structure, fixings and cable route before ordering, and book a free site survey so our team can confirm mounting height, sightlines and access. The data gives a maximum facedown tilt of 15 degrees under stated conditions (within 30 °C and 50% humidity), so set the angle during the survey rather than assuming it. The stated operating range is 0 °C to 40 °C with 10% to 80% humidity. Doha summers can push temperatures above 45 °C, so place the display in an air-conditioned space, keep it out of direct sunlight and ensure airflow around the cabinet.

Connectivity, control and monitoring

The unit offers three HDMI inputs with HDCP 2.2 and 1.4, a USB 2.0 Type A port, an audio output, RS232C in and out, an RJ45 LAN input and an IR input. The display can send email notifications when a problem is detected, such as the unit being tilted by an external impact. Sensors such as temperature sensors, GPIO or NFC/RFID readers can connect through USB. It has been certified Crestron Connected and certified for compatibility with Cisco video conferencing systems, so it can fit into a professional room AV setup. There is no OPS slot, so playback relies on the built-in webOS platform.

Where it fits in Qatar

Government reception: a ministry building in West Bay showing visitor directions and service information in Arabic and English.
Hospital waiting area: a clinic in Doha displaying patient wayfinding and health awareness content in a space that stays air-conditioned.
Campus corridor: a training centre in Education City showing timetables and event news along a busy corridor.

Questions about 49UM3DG

Who is the LG 49UM3DG designed for?

It is a standard signage display for indoor spaces that need clear, always-on information. Typical buyers in Qatar include government reception areas, hospital waiting rooms and university corridors where a 49-inch screen fits a wall without a large video wall. Its rating of 18 hours of operation per day suits busy public areas. Request a quote to confirm the right quantity for your site.

Does the 49UM3DG need an external media player?

No. The unit runs the LG webOS platform on a built-in quad-core processor, and the source data lists no OPS slot. Content is managed with SuperSign software, which is listed as compatible, so a school or ministry can run a small signage network without buying separate media players. Request a quote and we will confirm the software bundle for your project.

Can it be installed in a sunny lobby or near a window in Doha?

The stated operating temperature is 0 °C to 40 °C with 10% to 80% humidity. Doha summer temperatures can exceed 45 °C, so the screen should sit in an air-conditioned lobby with no direct sun on the panel and clear airflow around the cabinet. For semi-open or heat-exposed areas, confirm the environment with the SmartRooms Qatar team during the site survey before ordering.

What does the IP5x rating mean for a dusty site?

IP5x means the enclosure is certified as dust protected, and LG states that this prevents performance degradation caused by dust. That suits sites affected by sand and dust storms, such as an industrial office in Mesaieed or a logistics hub near the Industrial Area. The data does not list a water-resistance rating, so keep the display indoors and out of wet areas.

Will it run on Qatar's 240 V mains supply?

The built-in power supply is rated AC 100-240V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical draw is 85 W and maximum draw is 120 W, equal to 290 and 409 BTU per hour. Confirm the supplied power cord and plug arrangement with our team before installing units across a site.

Is it compatible with Cisco video conferencing and Crestron control?

The source data states that the 49UM3DG is certified Crestron Connected for integration with professional AV controls, and that it has been certified for compatibility with Cisco systems for meeting control. A boardroom in Msheireb or a meeting room linking Doha with teams abroad can use it within that setup. Confirm the exact Cisco and Crestron versions with your quotation.

How do I mount it and what tilt is allowed?

It uses a 300 x 300 VESA mounting pattern, and the optional LSW240B wall bracket and ST-653T stand are available. The data gives a maximum facedown tilt of 15 degrees under stated conditions. The head weighs 15.4 kg, so check the wall structure first. SmartRooms Qatar offers a free site survey to confirm height and fixings, followed by professional installation.

How much power and heat should a lobby with several units plan for?

Typical draw is 85 W and maximum draw is 120 W per unit, with heat output of 290 BTU per hour typical and 409 BTU per hour maximum. A reception wall of four units in a Lusail office would draw up to about 480 W at maximum, so the air-conditioning should be sized to handle that load together with other equipment in the room.

What software is needed to manage content across several displays?

The data lists SuperSign CMS, SuperSign Control and Control+, SuperSign WB, SuperSign Media Editor and Signage365Care as compatible. Signage365Care availability varies by region, so confirm that option for Qatar. A school group with displays across several campuses can manage content from one central system. Request a quote and we will confirm the software bundle for your order.

Can it alert us if a screen is knocked or fails?

Yes. The source describes email notifications when a problem occurs, such as the display being tilted by an external impact, so staff are informed right away. The unit includes an RJ45 LAN input for the network connection. For a hospital or bank with limited staff on the floor, this reduces the time spent checking each screen manually. Confirm the alert setup during the quotation.

What accessories come in the box and what can I add?

The basic package includes a remote controller, power cord, quick start guide, regulation book and a phone-to-RS232C adapter. Optional items are the ST-653T stand, LSW240B wall bracket and AM-B220S VESA adapter. The built-in speaker means separate speakers are not needed for basic audio. Request a quote listing the accessories you need for your site.
