What the LG 98UM3DG-H is built for

The LG 98UM3DG-H is a 98-inch large screen display designed for digital signage. Its 3840 x 2160 UHD resolution, four times the pixel count of Full HD, gives sharp text and fine detail at this size. An IPS panel with a 178 x 178 degree viewing angle keeps content readable for people standing across a lobby or beside the screen.

Because this model is discontinued, owners who already run it and buyers comparing it with newer displays both need clear facts. The points below cover what the specification sheet states for this exact model.

Specifications that matter to a buyer

Brightness: 350 nit typical, with a 28% haze surface that reduces reflections under bright lighting.
Colour: 10-bit panel showing about 1.07 billion colours with 95% BT709 gamut coverage.
Contrast: 1,200:1 static and 1,000,000:1 dynamic.
Response: 8 ms grey-to-grey.
Operation: rated for 24/7 use, with portrait and landscape orientation supported.

Connectivity, control and remote management

Three HDMI inputs with HDCP 2.2/1.4 support, an RJ45 LAN port, a USB 2.0 Type A port, and RS232C in and out let the display connect to media players, AV controllers and network monitoring. An IR input accepts infrared control. The built-in webOS platform runs on a quad-core SoC for smooth content playback, and SDK tools are listed for developers building custom apps. Control Manager provides web monitoring of displays in different sites, and the model supports Crestron Connected for AV control integration and Cisco systems for video conferencing control. External sensors such as GPIO, NFC/RFID and temperature sensors can be added through USB.

Where it fits in Qatar

A hotel lobby in West Bay or Lusail can use the screen to show arrival details, wayfinding and event information from one wall. A university entrance in Education City can run a continuous loop of announcements, with the built-in speakers adding short audio clips without a separate sound system. A government authority in Msheireb or the Industrial Area can use it in a reception hall to display service instructions and opening times.

Planning before you order

The head weighs 81.1 kg and measures 2191.8 x 1246.8 x 83.8 mm without the handle, with an 800 x 400 VESA mounting pattern. Plan a wall or stand rated for that load, a lifting team, and a site survey before installation. SmartRooms Qatar offers free site surveys to confirm wall structure, cable routes and power points. The operating range is 0 °C to 40 °C with 10% to 80% humidity, so install the display in air-conditioned indoor spaces. Summer temperatures in Qatar can exceed 45 °C, so confirm room conditions with the SmartRooms Qatar team before installation. Power draw is 355 W typical and 435 W maximum, on built-in AC 100-240 V, 50/60 Hz power.

This model has been discontinued by the manufacturer. If you need a current equivalent or a compatible replacement, request a quote from SmartRooms Qatar and share your room size, mounting wall and connection needs so we can match the options to your site.

Questions about 98UM3DG-H

Is the LG 98UM3DG-H still in production?

No. The manufacturer has discontinued this model, so check availability before planning a project. SmartRooms Qatar can quote a current equivalent or a compatible replacement for your site, and quotations usually come back within one working day. Send us the room size, mounting wall and connection needs so we can compare options against this model's specifications.

What is this display best suited for?

It suits large information walls where text must be read from across a room, such as hotel lobbies in West Bay or Lusail, hospital waiting areas, university entrances and retail atriums. The 98-inch 3840 x 2160 IPS panel gives sharp text at distance, and the 24/7 operation rating supports continuous playback of schedules, wayfinding and announcements. It is a poor fit for individual desk use.

Will the picture stay readable near windows or under bright lobby lighting?

The panel is rated at 350 nit typical brightness and has a 28% haze surface that reduces reflections under bright lighting. Direct sunlight through glass is still a problem in Qatar, where summer temperatures can exceed 45 °C. Position the screen away from windows and confirm the lighting and room temperature with the SmartRooms Qatar team before installation.

Can it be mounted in portrait for a tall corridor or stairwell?

Yes, the source lists both portrait and landscape operation. In portrait, the 2191.8 mm side becomes the height, so the panel stands about 2.2 metres tall and 1246.8 mm wide. Check ceiling clearance, wall width and the 800 x 400 VESA pattern before ordering. Hotel stairwells and mall corridors in Doha are typical places where this orientation helps.

What connections does it have?

It has three HDMI inputs with HDCP 2.2/1.4 support, one RJ45 LAN port, one USB 2.0 Type A port, RS232C in and out on 4-pin phone-jack connectors, an IR input and an audio output. A media player, laptop, AV controller or building system can connect through these ports. A phone-to-RS232C gender adapter is included, but confirm other cable adaptors with your installer.

Can it be controlled from a meeting room AV system?

Yes. The display supports Crestron Connected for integration with professional AV control systems, and it is compatible with Cisco systems for video conferencing control. The RS232C and IR inputs also let a controller send commands. Ask the SmartRooms Qatar team to confirm your controller model and command set before ordering, especially for a boardroom linked to teams abroad.

How do we manage several displays across different sites?

The built-in Control Manager provides web monitoring, so administrators can check status and control displays in different locations in real time from internet-connected devices. This helps when a fault at a school, clinic or ministry branch needs a quick response. An optional ConnectedCare cloud service is also listed for remote fault diagnosis. Ask about its availability and terms as part of your quotation.

Does it need external speakers?

External speakers are not needed for basic announcements or short audio loops, because the display includes built-in speakers. An audio output is also provided if you want to feed a larger sound system. In a large atrium or event venue, test the built-in speaker level on site and decide whether an external system is needed for the room size.

What should we plan for the weight and mounting?

The head weighs 81.1 kg and measures 2191.8 x 1246.8 x 83.8 mm without the handle. Plan a wall or stand rated for that load, a lifting team, and a site survey before installation. SmartRooms Qatar offers free site surveys, which help confirm wall structure, cable routes and power points in older buildings, including those in Al Sadd or the Industrial Area.

What is the power consumption, and does it suit Qatar's power supply?

The built-in power supply is rated AC 100-240 V, 50/60 Hz, a range that covers Qatar's 240 V mains. Typical draw is 355 W and maximum is 435 W, equal to 1211.44 BTU/hr typical and 1484.44 BTU/hr maximum. Use these figures when planning circuits and the air-conditioning load for the room.

Can a school or ministry order several units on one LPO?

Yes, SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including those published on Monaqasat. Because this model is discontinued, stock for a multi-unit order may be limited, so confirm quantities, the estimated lead time and matching specifications in the quotation. Payment is by bank transfer, cheque or purchase order. Request a quote with the number of units and their locations.
