LG 75TR3PN · Price in Qatar

Overview

The LG 75TR3PN is a 75-inch 4K interactive digital board built on an IPS panel, with 50-point multi-touch and a built-in OPS slot for adding PC software without an external desktop. It runs Android 13 and includes a slot-type Wi-Fi module and four HDMI inputs. It suits meeting rooms and classrooms in Qatar that need to share content from several devices at once.

A 75-inch board for writing, sharing and presenting

The LG 75TR3PN combines a 75-inch display, touch input, a built-in Android 13 system and a slot for an OPS computer module. It suits teams that write, annotate and share material in the same session, whether the person at the board is a teacher, a presenter or a meeting host. The 3840 x 2160 resolution keeps small text and detailed charts sharp when viewed from the back of a room.

Display and touch performance

The IPS panel uses a 16:9 aspect ratio, a typical brightness of 400 nits, a 4,000:1 contrast ratio and a dynamic contrast figure of 5,000:1. Viewing angles of 178 degrees horizontally and vertically keep text readable for people seated away from the centre. Colour gamut is rated at 72% NTSC, with 10-bit colour produced through 8-bit plus FRC, a 60 Hz refresh rate and an 8 ms typical response time.

Multi-touch detects up to 50 points at the same time
Touch objects from Ø2 mm are detected, with typical accuracy of ±1 mm
3.2 mm protection glass with 88% transmission
Two writing pens are included for note-taking

Connectivity, OPS and wireless sharing

Some ports sit on the front, so cables can be changed without reaching behind the screen, while the power connector is located on the side and back. Inputs include four HDMI ports, one DisplayPort, two USB-C ports, four USB 3.0 Type A ports, three USB 2.0 Type A ports and an RS232C input, with LAN in and out. The built-in OPS slot takes a module mounted at the back of the screen, so Windows software can run without a separate desktop. LG CreateBoard Share handles wireless sharing from personal devices and can display up to nine screens at once.

Where it fits in Qatar

A private school in Al Wakrah equipping a mid-sized classroom can use the board so the teacher presents from anywhere in the room while students come up to the screen. A consultancy in West Bay holding meetings with colleagues abroad can have several presenters share from their own laptops without swapping cables. Training rooms in Education City can run workshops where materials are saved, shared by email or transferred by QR code after each session.

Planning the installation

The head unit weighs 51.4 kg and ships in a 60.7 kg carton, so a lifting plan and a wall or stand rated for that load are essential. Dimensions are 1709 x 1031 x 86 mm, with a VESA interface of 800 x 400 mm. The operating range is 0 to 40 °C at 10 to 90% humidity, so the board belongs in an air-conditioned room, not beside glazing in a sunny lobby. Typical power draw is 210 W and maximum 450 W, with a built-in power supply rated 100 to 240 V at 50/60 Hz. SmartRooms Qatar offers a free site survey to check wall loading, cable routes and room cooling before installation.

Questions about 75TR3PN

What is the LG 75TR3PN best suited for?

The 75TR3PN suits medium-sized classrooms, meeting rooms and training rooms where a small group writes, annotates and shares material on one screen. Its 75-inch 4K panel and 50-point touch let several people work at the board together. Large lecture halls or boardrooms may need a bigger size, so compare this model with other screen sizes before ordering.

Does the board have its own computer?

It runs Android 13 with 8GB RAM and 64GB storage. For Windows software it has a built-in OPS slot with power, which takes an OPS module mounted at the back of the screen, so no separate desktop is needed. The standard accessory list does not include an OPS module, so add one to your quotation if you need Windows applications.

How many people can use the touch surface at the same time?

Multi-touch detects up to 50 touch points at once, so a class can solve a problem or sort cards together without waiting for turns. Touch detects objects from 2 mm in diameter with typical accuracy of ±1 mm. Two writing pens are included, and fingers work too. In a Doha classroom, this suits group activities where students stand at the board together.

Can the on-screen menus be set to Arabic?

Yes. The on-screen display languages listed for the 75TR3PN include Arabic alongside English, French, German, Spanish and many others. This helps ministries and schools that work in Arabic and English side by side set menus to the language their users prefer. Confirm the interface language on the unit when you order, and ask our team about any Arabic content you plan to display.

Can it run in a classroom without air conditioning?

No. The operating range is 0 to 40 °C with 10 to 90% humidity, while outdoor temperatures in Qatar's summer often exceed 45 °C. Install it in an air-conditioned room, away from direct sunlight and glazing, and keep ventilation paths clear. Confirm the installation environment with the SmartRooms Qatar team before you request a quote.

What connections are available for laptops and presentation sources?

The board has four HDMI inputs, one DisplayPort input, one HDMI output, two USB-C ports, four USB 3.0 Type A ports, three USB 2.0 Type A ports, and LAN in and out, plus an RS232C input. Some ports sit on the front for easy cable changes, while the power connector is on the side and back of the unit.

Can presenters share their screens wirelessly?

Yes. LG CreateBoard Share works through its app or a website, and a 6-digit code connects a device quickly. Up to nine screens can be shown at once, and presenters can move around the room without plugging and unplugging cables. The wireless connection relies on the Wi-Fi module listed in the standard accessories, which supports 802.11 a/b/g/n/ac/ax.

What security features protect confidential material?

Secure Mode lets users grant sharing permissions to stop unauthorised content from appearing. Screen Lock requires a password, USB Lock Mode helps stop data being copied to unauthorised devices, and Auto-remove Files deletes files on a schedule. QR login can be signed out after use. These features suit government offices in Msheireb or any team handling internal documents.

Can IT staff manage several boards remotely?

Yes, through LG ConnectedCare DMS, a cloud solution for monitoring, controlling and managing boards and signage. Staff can power units on and off, set schedules and adjust brightness from a dashboard, and send urgent alert messages across the system. A school with several classrooms in Doha can manage them from one place without visiting each room.

What space and wall loading does installation need?

The head unit weighs 51.4 kg and ships in a 60.7 kg packed carton. Its dimensions are 1709 x 1031 x 86 mm, with a VESA interface of 800 x 400 mm. The optional WM-L000S wall mount and ST-000F or ST-860F floor stands are listed for it. SmartRooms Qatar offers a free site survey to check wall strength, sightlines and cable routes before mounting.

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

Yes. SmartRooms Qatar supplies against purchase orders (LPOs) and government tenders, including those on Monaqasat, and accepts payment by bank transfer, cheque or purchase order. Quotations are usually issued within one working day. Ask for the quotation to list the model, optional mounts and installation so your procurement file is complete.
