Overview

The LG 75TR3DQ is a 75-inch interactive display from the CreateBoard TR3DQ series, built around a 3840 x 2160 VA panel and up to 50 simultaneous touch points. It runs Android 14 with 8GB RAM and 64GB storage, includes a built-in OPS slot for a PC module sold separately, and supports wireless sharing of up to 9 screens. Suited to classrooms, universities and meeting rooms across Qatar.

A 75-inch board for shared writing and presenting

The LG 75TR3DQ is a 75-inch interactive display from the CreateBoard TR3DQ series, built on a 16:9 VA panel with a native resolution of 3840 x 2160 (UHD) and a 60Hz refresh rate. Typical brightness is 400 nit, the contrast ratio is 5500:1, and the 6.5 ms response time keeps moving content clear. The 3.2 mm protection glass is tempered, anti-reflective and shatter-proof, which suits busy classrooms and boardrooms where the surface gets daily use. The black-bezel variant is listed as 75TR3DQ-B.

Touch, writing and sharing on one surface

Touch detects up to 50 points at once, so several people can annotate, pinch to zoom and turn content at the same moment without taking turns at the board. Touch response is 5 ms, the writing height is 2 mm or less and accuracy is ±1 mm. Built-in tools such as a ruler, table, calculator, clock and sticky notes help teachers build lessons on the spot, and the menu bar can be arranged around the tools you use most. Files can be saved and imported from Google Drive or OneDrive, emailed after a session, or moved to a personal device by scanning a QR code.

Connectivity, computing and room control

The front has one HDMI input, two USB 3.0 ports, one USB Type-C port and a touch USB connection, so a laptop can be plugged in without reaching behind the screen. Across the unit you also get DisplayPort, VGA and RS232C inputs, an RJ45 LAN port, an HDMI output and an optical audio output. The board runs Android 14 with 8GB of RAM, 64GB of storage, Wi-Fi 6E and Bluetooth 5.3, and it has a built-in OPS slot for a PC module that is sold separately.

Wireless sharing: presenters can share from a PC, tablet or smartphone, with a 6-digit code to connect and up to 9 screens shown together.
Remote management: LG ConnectedCare supports monitoring, power control and scheduling across several boards.

Where it fits in Qatar

In a university lecture theatre in Education City, the large panel lets a lecturer work from anywhere in the room, while live captions and translation help students who follow the lesson in a second language or who have a hearing impairment. In a boardroom in West Bay or Lusail, a Doha team can share laptop content wirelessly while colleagues join from abroad. In a private school in Al Rayyan or Al Wakrah, several classroom boards can be checked and managed from a central office, and the on-screen menu can be set to Arabic (Egypt) for staff who work in Arabic.

What to plan before you order

Settle the wall or mounting arrangement before the board arrives. The head weighs 43.85 kg, the packed weight is 57.3 kg and the monitor measures 1709.4 x 1031.1 x 99.7 mm. The VESA interface is 800 x 400 mm, so confirm your bracket matches. The panel is landscape only. Power is rated 100-240V AC at 50/60Hz, with typical consumption of 175W and a maximum of 365W. The operating range is 0°C to 40°C, so the room must be kept within that range through the Qatari summer. Included accessories are a 3 m power cord, a 3 m HDMI cable, a USB Type-A to Type-B cable, a USB-C cable, two writing pens, a remote controller and a Wi-Fi module. An optional accessory, WIB9060H, is also listed.

SmartRooms Qatar supplies the 75TR3DQ across all eight municipalities, with professional installation and free site surveys before wall mounting. Request a quote today and our team will usually reply within one working day, with LPOs and government tenders accepted.

Questions about 75TR3DQ

Who is the LG 75TR3DQ built for?

The LG 75TR3DQ is a 75-inch interactive board for classrooms, lecture theatres, boardrooms and collaboration rooms where people write, annotate and share content by touch. It suits a school or university in Doha that needs one large shared surface, or a company meeting room where presenters connect from their own laptops. Its 3840 x 2160 resolution and 50-point touch make it practical for groups working at the screen together.

Does the 75TR3DQ run Android, and how much memory does it have?

Yes. The board runs Android 14 (EDLA) with an octa-core processor, 8GB of RAM and 64GB of storage. It also has Wi-Fi 6E, Bluetooth 5.3 and a gigabit LAN port. Built-in tools such as a ruler, table and sticky notes run on the panel itself, so teachers and meeting hosts do not need a separate computer for them.

How accurate is the touch, and how many people can write at once?

Touch detects up to 50 points at the same time, so several users can write, drag and zoom together. The data lists a touch response time of 5 ms, a writing height of 2 mm or less, accuracy of ±1 mm, and detection of objects from 2 mm in diameter. The touch interface uses USB 2.0 and supports Windows, Android, Linux and macOS, with Linux and macOS limited to one touch point.

Can I add a PC to the 75TR3DQ?

Yes, through the built-in OPS slot at the back of the screen, which has built-in power. An OPS module adds PC functions and Windows software without a separate desktop cabled to the board. The OPS slot is sold separately, so include the module in your request. The front USB-C port delivers PD 65W only when no OPS module is installed.

Which inputs and ports are on the board?

The board has three HDMI inputs (one at the front and two at the back), one DisplayPort input, one VGA input, one audio input, one RS232C input and one RJ45 LAN input. Outputs include one HDMI, one audio output, an optical SPDIF output and one RJ45 LAN output. USB includes five USB 3.0 Type-A ports, one USB 2.0 Type-A port and two USB Type-C ports, with front-facing ports easing cable changes while some ports sit on the side and back.

How does wireless screen sharing work, and how many screens can connect?

Presenters share from their own PC, tablet or smartphone using LG CreateBoard Share, either through the app or the website. A quick connection is made by entering a 6-digit code. Up to 9 screens can be displayed in real time, and Secure Mode lets administrators grant sharing permissions so unauthorised users cannot share their screens, which is useful for internal meetings with sensitive material.

Can the board handle Qatar's summer heat?

The stated operating temperature range is 0°C to 40°C, with humidity of 10% to 90%. Outdoor temperatures in Qatar can exceed 45°C in summer, so the board should sit in an air-conditioned room, not a sun-facing lobby where cooling may fail. Confirm the installation environment with the SmartRooms Qatar team before the site survey, especially for rooms with large windows or heavy dust exposure.

Does the on-screen menu support Arabic?

Yes. The on-screen display (OSD) language list includes Arabic (Egypt) alongside English and many other languages. This lets staff or students who prefer Arabic set up the board in their language while English-language lessons and meetings continue on the same screen. If your team needs a specific Arabic interface, ask the SmartRooms Qatar team before placing your order.

What wall space and structure should I plan for?

The monitor measures 1709.4 x 1031.1 x 99.7 mm, the head weighs 43.85 kg and the packed weight is 57.3 kg. The VESA mount interface is 800 x 400 mm, so check that your wall bracket matches before ordering. SmartRooms Qatar offers free site surveys, which help confirm wall load, cable routes and access to the lift or stairwell before the board arrives on site.

How does live captioning and translation work during a lecture?

The AI Live Subtitle feature generates captions and translations into the user's preferred language by recognising sound from system audio and microphones, and it can detect sound within 8 meters. It can help students facing language barriers or hearing impairments follow a lesson at a university in Education City or a school in Al Rayyan. Because translations can contain errors, teachers should verify critical information independently.

Can I manage several boards across a school or company from one place?

Yes, with LG ConnectedCare, a cloud solution for remotely monitoring, controlling and managing LG CreateBoard and LG signage displays. IT managers can view multiple devices on one dashboard, switch power on or off, adjust brightness and schedule functions. In an emergency such as a fire, alert messages can be distributed across the whole system so staff and students act quickly.

Can a government body or school buy it with an LPO or through a tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat tenders, and payment by bank transfer, cheque or purchase order. Each 75TR3DQ is sold by quotation, so send the model, quantity and delivery location, and the team will usually reply within one working day. Products are covered by the manufacturer's warranty, and deliveries go to all eight municipalities.
