LG 75TR3BQ · Price in Qatar

Overview

The LG 75TR3BQ is a 75-inch interactive digital board with a 4K UHD panel, a multi-touch overlay that detects up to 40 touch points and a built-in OPS slot for a compatible PC module, sold separately. It offers three HDMI inputs, a USB-C port and an RJ45 LAN connection, and it works with Windows, Android, Linux, macOS and Chrome. It suits classrooms, boardrooms and training rooms across Qatar that need one shared screen for writing and presenting.

A 75-inch 4K board for shared writing and presenting

The LG 75TR3BQ is a 75-inch interactive digital board built around a 3840 x 2160 UHD VA panel. It is rated at 350 nit typical brightness with a 5500:1 contrast ratio, and its 60Hz refresh rate suits presentations, video playback and on-screen annotation. Viewing angles are rated at 178 degrees horizontally and vertically, so people seated at the sides of a room can still read the content.

The touch layer detects up to 40 simultaneous touch points, with a response time of 10 ms or less, a writing height of 2 mm or less and an accuracy of plus or minus 1.5 mm. Objects 3 mm in diameter or larger register as input. The 3.2 mm tempered, anti-reflective protection glass carries an 88% transmission rating.

Connectivity, OPS and built-in audio

Several ports sit on the front of the unit for quick cable changes, while the power connector and some others are on the side and back. The main connections are:

Video: three HDMI inputs and one USB-C port
USB: four USB 3.0 Type A, one USB 2.0 Type A and two touch USB outputs
Audio: one audio input, one audio output and an optical SPDIF output
Network and control: RJ45 LAN in and out, RS232C input, Wake on LAN and HDMI-CEC
OPS: a built-in slot with OPS power included; the OPS module is sold separately

Two 16 W speakers are built in, so the board can play sound for a classroom or meeting room without external speakers. The on-screen menu lists more than thirty languages, including Arabic (Egypt).

Where the 75TR3BQ fits across Qatar

A private school in Al Wakrah fitting out a mid-sized classroom can use the 75-inch screen for lessons where a teacher and students annotate the same slide. A corporate meeting room in West Bay or Lusail can connect a laptop over HDMI or USB-C, or run a PC from the OPS slot, so a Doha team can present to colleagues abroad. A university department in Education City can set up a seminar room where Wake on LAN and HDMI-CEC help the room start up before a session.

What to plan before ordering

The rated operating range is 0°C to 40°C with 10% to 90% humidity. Qatar summer temperatures often pass 45°C, so the board belongs in an air-conditioned indoor room and should not sit in a sun-facing lobby or an outdoor enclosure. The head weighs 42.8 kg, and the VESA pattern is 800 x 400 mm. The wall mount WM-L000S and the floor stands ST-000F and ST860F are listed as optional, so confirm the mounting plan during a free site survey before wall-mounting. Power input is 100-240 V at 50/60 Hz, with typical draw of 167 W and maximum of 396 W. For several units, an LPO can be raised for the whole order.

Questions about 75TR3BQ

Who is the LG 75TR3BQ built for?

The LG 75TR3BQ suits rooms where a small group writes, annotates and presents on one screen, such as a 75-inch classroom, a departmental meeting room or a training room in a Doha office. The 4K UHD panel keeps text sharp for documents and spreadsheets, and up to 40 touch points let several people work at once. Teams running Windows, macOS, Android or Chrome can connect their own devices without changing their setup.

Does the 75TR3BQ include an OPS computer?

No. The board has a built-in OPS slot with OPS power included, so a compatible OPS module can sit behind the screen instead of a separate desktop. The OPS module is sold separately and should be included in your quotation. Once fitted, it lets the room run Windows software directly through the display, which saves desk space and cabling in lecture rooms and training rooms.

Which operating systems does it support?

The source data lists support for Windows 7, Windows 8, Windows 10, Android, Linux, macOS and Chrome. The board integrates with devices running these systems through its HDMI inputs, USB-C port and USB connections, so staff are not limited to one laptop type. Confirm your exact device and any OPS module software with the SmartRooms Qatar team when you request a quote.

How many people can write on it at the same time?

The touch layer detects up to 40 touch points at once, which supports several users writing or gesturing together. The touch response time is 10 ms or less, the writing height is 2 mm or less, and objects from 3 mm in diameter register as input. In a 75-inch meeting room or classroom, groups can brainstorm at the board without queuing for a single input point.

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

Yes. The power input is rated at 100-240 V and 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains supply. Typical power draw is 167 W and maximum is 396 W. Qatar sockets are BS 1363 (Type G), but the source data does not list a plug type, so ask the SmartRooms Qatar team to confirm the power cord on your order before installing in a school or office in Doha or Al Rayyan.

Can I install it in a lobby or outdoors in Qatar?

No. The rated operating temperature is 0°C to 40°C with humidity from 10% to 90%. Qatar summer temperatures often exceed 45°C, so the board should be installed in an air-conditioned indoor room. Keep it away from direct sunlight and large windows, and avoid outdoor or semi-enclosed lobbies, including sites in the Industrial Area or Ras Laffan where dust is a concern.

How heavy is it and what mounting does it need?

The head weighs 42.8 kg and has two handles, so two people should lift it. The VESA mounting pattern is 800 x 400 mm, and the WM-L000S wall mount is listed as an optional accessory. The board measures 1712 x 1022 x 98 mm, so allow for depth and clearance. Before wall-mounting in a Doha meeting room, request a free site survey to check wall structure, height and cable routing.

Which stands and wall mounts are available?

The source data lists the WM-L000S wall mount and the ST-000F and ST860F floor stands as optional accessories. The basic accessory list is not yet confirmed in the data, so your quotation will show what comes in the box and what must be ordered separately. A school in Al Khor setting up a mobile teaching room may choose a floor stand, while a boardroom in West Bay will usually take a wall mount.

Can it be controlled from a room system?

Yes. The board has an RS232C input for control commands, RJ45 LAN in and out, Wake on LAN and HDMI-CEC, which help it fit into a managed AV setup. A university lecture theatre in Education City could use network wake-up to bring the display on before a session. Your integrator should check the command set against your control system before ordering.

Is the on-screen menu available in Arabic?

The on-screen display language list includes Arabic (Egypt) alongside English and many other languages. This helps Arabic-speaking staff in a Qatari ministry or school navigate the menus. The data does not describe Arabic handwriting or text input features, so ask the team to confirm any specific Arabic functions you need before placing an order.

What energy use should I expect?

Typical power draw is 167 W and maximum is 396 W, with 0.5 W in standby and power-off modes. The board also includes a smart energy saving feature. Its heat output is listed at 570 BTU/hr typical and 1351 BTU/hr maximum, which matters when planning air conditioning for a small room in Doha during the summer.

Can we order several units under an LPO or government tender?

Yes. SmartRooms Qatar supplies interactive boards to organisations across Qatar and delivers to all 8 municipalities. Schools, ministries and companies can issue a purchase order (LPO) or respond to a government tender, including Monaqasat. Payment can be made by bank transfer, cheque or purchase order, and quotations are usually provided within one working day.
