LG 75TR3ER · Price in Qatar

Overview

The LG 75TR3ER is a 75-inch interactive digital board with a 4K UHD panel, 50-point multi-touch and built-in Android 16 with 8GB RAM. It offers wireless sharing from up to four screens, an OPS slot for a PC module and a rating of 16 hours a day, 7 days a week. It suits classrooms, training rooms and meeting rooms across Qatar that need interactive teaching and collaboration without tangled cables.

A 75-inch 4K touch board for active lessons and meetings

The LG 75TR3ER belongs to LG's CreateBoard TR3ER series. It pairs a 75-inch VA panel at 3840 x 2160 resolution with a touch layer that detects up to 50 points at once, so several people can write, draw and move content together. The board runs Android 16 on an octa-core processor with 8GB of RAM and 128GB of internal storage, so its whiteboard tools work without a connected computer.

Specifications that shape daily use

The panel offers 350 nits typical brightness, a 5,500:1 contrast ratio and a 178 by 178 degree viewing angle, which keeps material readable from the back of a room. The 3mm tempered, anti-reflective protection glass has 88% light transmission and registers touch from objects 3 mm in diameter with accuracy of ±2 mm. The unit is rated for 16 hours a day, 7 days a week, and its panel life is listed at 50,000 hours (L30).

Touch: up to 50 simultaneous points, USB 2.0 Type B touch connections
Built-in extras: Wi-Fi 6, Bluetooth 5.4, Gigabit LAN and 2 x 20W speakers
Teaching tools: templates for rulers, tables, sticky notes, a calculator and a clock

Wireless sharing and connections

CreateBoard Share lets presenters send a screen from a PC, tablet or smartphone, with up to four screens displayed at once. A six-digit code makes the connection, and the same feature can be reached through a web browser without installing the app. Wired connections include three HDMI inputs, a front USB-C port with display output and 65W power delivery, three USB 3.0 Type-A ports, a Gigabit LAN port and RS232C control. USB-C cables are sold separately.

Where it fits in Qatar

A secondary school in Al Wakrah replacing an older projector could use this board in a science lab, where teachers move freely around the room and use the built-in templates during the lesson. A consultancy in West Bay running client workshops can let several team members share laptop screens without swapping cables. For a government training centre in Msheireb, LG ConnectedCare gives IT staff one dashboard to power, schedule and check boards remotely, and alert messages can reach every screen during an urgent event.

What to plan before ordering

Confirm that the room is air-conditioned. The operating range is 0°C to 40°C with 10% to 90% humidity, and Qatar summer temperatures can exceed 45°C, so the board should not sit in direct sun or near dusty windows. Its built-in power accepts 100 to 240V at 50/60Hz, which covers Qatar's 240V mains supply. A wall mount (WM-L000S) and floor stand (ST-000F) are listed as optional accessories. A free site survey lets our team check wall construction and sight lines before a 75-inch panel is mounted. An OPS module, sold separately, adds Windows software if you need it.

Schools and government buyers ordering several units can issue a purchase order or LPO, and SmartRooms Qatar delivers to all eight municipalities of Qatar with professional installation available. Request a quote and our team will usually respond with pricing within one working day.

Questions about 75TR3ER

What is the LG 75TR3ER used for?

The LG 75TR3ER is an interactive digital board for teaching, training and meetings. Users write, draw and annotate directly on a 75-inch 4K touch surface with up to 50 touch points. Its built-in whiteboard tools, including a ruler, table and sticky note, suit lessons in a science lab or a team workshop where several people contribute at the same time.

Who is this 75-inch board best suited to in Qatar?

The 75-inch size suits medium to large rooms: classrooms, training rooms and mid-sized boardrooms in schools, universities and companies across Doha, Lusail and Al Rayyan. For a lecture hall or a large boardroom, you may want a bigger panel. A site survey helps confirm whether the viewing distance and room layout match this size.

Can the board be used in a room without air conditioning during Qatar's summer?

No. The operating temperature range is 0°C to 40°C and the humidity range is 10% to 90%. Qatar summer temperatures can exceed 45°C, so the board should be installed in an air-conditioned room, away from direct sunlight and dusty windows. Confirm your room conditions with the SmartRooms Qatar team before ordering.

Can several presenters share their screens at the same time?

Yes. CreateBoard Share supports wireless screen sharing from a PC, tablet or smartphone and can display up to four screens at once. A six-digit code connects each device, and the web route works without installing the app. In a meeting in West Bay with team members joining from different offices, presenters can swap in and out without touching any cable.

Which ports does the board have for laptops and peripherals?

The board has three HDMI inputs, a front USB-C port with display output and 65W power delivery when no OPS module is fitted, three USB 3.0 Type-A ports, one USB 2.0 Type-A port, two USB Type B touch connections, a Gigabit LAN port, RS232C control and audio input and output. USB-C cables are sold separately, so include one in your order.

How does LG ConnectedCare help IT managers with several boards?

LG ConnectedCare is a cloud tool for monitoring, controlling and managing LG CreateBoard and LG signage displays. IT staff can power boards on or off, set schedules and adjust brightness remotely, and view several devices on one dashboard. For a government training centre in Msheireb with boards across several floors, this avoids a site visit for routine changes.

Can the board be wall-mounted or placed on a stand?

A wall mount (WM-L000S) and a floor stand (ST-000F) are listed as optional accessories for this model. Before mounting a 75-inch panel, check wall construction, load and sight lines. SmartRooms Qatar offers a free site survey to plan the mounting position and cable routing, which is useful in newly fitted classrooms in Education City or Lusail offices.

Does the board work with Google accounts and Google Drive?

The board has Google certification, so users can connect their Google accounts and access the Google ecosystem, and the Google Play Store is available. Resources can be imported from and exported to Google Drive or OneDrive. A Google account is required for these services, and availability varies by country, so confirm the setup with the SmartRooms Qatar team before ordering.

Can a public organisation buy this board through a tender or LPO?

Yes. SmartRooms Qatar supports purchase orders (LPOs) and government tenders, including Monaqasat, and accepts payment by bank transfer, cheque or purchase order. A school or ministry ordering several LG 75TR3ER boards can request one quotation covering all units, with delivery to any of Qatar's eight municipalities and professional installation included in the scope.

What security features does the board include for sensitive rooms?

The board includes Secure Mode, which lets users grant permission before a screen is shared, and Screen Lock, which requires a password. USB Lock Mode helps prevent data being copied to unauthorised devices, and Auto-remove Files can delete stored files on a schedule. These features suit government offices, hospitals and banks where meeting content is confidential.
