LG 84TR3B (Discontinued) · Replacements in Qatar

Name: LG 84TR3B 84-inch UHD Interactive Digital Board
Brand: LG
SKU: lg-84tr3b
Availability: Discontinued

Overview

The LG 84TR3B is an 84-inch interactive digital board from the CreateBoard TR3B series, with a 3,840 x 2,160 UHD panel and 350 cd/m² typical brightness. The manufacturer has discontinued this model; SmartRooms Qatar quotes a current equivalent or compatible replacement. It recognises up to 10 simultaneous touches, a good fit for lecture halls and boardrooms in Doha, Education City and Lusail.

What the LG 84TR3B is and why its status matters

The LG 84TR3B is an 84-inch interactive digital board from the CreateBoard TR3B series, built around a UHD panel with 3,840 x 2,160 resolution. The manufacturer has discontinued this model. If your organisation already runs one, or you are comparing it with newer boards before buying, SmartRooms Qatar can quote a current equivalent or a compatible replacement that matches the room size and connections you need.

Touch, picture and connection facts

Multi-touch: recognises up to 10 simultaneous touches, so basic writing and drawing work with fingers and hands, and two touch pens are included when a pen is preferred.
Brightness: 350 cd/m² typical, reduced to 300 cd/m² when the protection glass is fitted.
Upscaling: up-scaling and super resolution processing improves FHD content toward near-UHD quality.
Inputs: two HDMI, one DisplayPort, one DVI-D, one component, an audio input, and USB ports (one USB 3.0 and two USB 2.0).
Control: RS232C in and out, LAN control, IR/light sensor input and pen tray control.
Limits to check: the data lists no analogue RGB input, and an external media player cannot be attached to the board.

Where it fits in Qatar

Three situations suit an 84-inch board of this kind:

A university lecture room in Education City where the lecturer and students mark up the same UHD slides in turn.
A ministry boardroom in Msheireb where presenters connect laptops over HDMI or DisplayPort and share content with the room.
A hotel conference room in Lusail hosting full-day workshops, where room lighting matters and the brightness rating is best reviewed in the actual space.

A reception lobby with large windows in West Bay needs a different check. At 300 cd/m² with protection glass, and with daylight coming through glass, ask the SmartRooms Qatar team to review placement before ordering. The source data gives no operating temperature range, so confirm the environment before a quote is finalised.

Planning the installation

The head weighs 104.0 kg and measures 1,951.2 mm x 1,137.2 mm x 111.9 mm, so the wall, bracket and lifting plan should be settled before delivery. The VESA pattern is 600 x 400 mm with M8 holes. Confirm that the bracket matches this pattern and that the wall can carry the load. SmartRooms Qatar offers a free site survey before wall-mounting a board this size. Two eye-bolt assemblies, a screw package and cable ties are supplied, and SuperSign-w lite is listed as compatible while SuperSign-c is not.

Ordering several boards for an institution

Schools and ministries buying more than one board can send a purchase order (LPO) or a government tender reference. Payment is possible by bank transfer, cheque or purchase order. Each unit comes with a remote controller and two batteries, USB 2.0, HDMI 2.0 and DisplayPort cables, and an IR/light sensor receiver, so list the quantities and rooms when you ask for a quote.

To replace an LG 84TR3B or to match a board already in service, request a quote from SmartRooms Qatar with your room size, connection list and mounting wall, and we will recommend a current equivalent or compatible replacement.

Questions about 84TR3B

Is the LG 84TR3B still sold by LG?

No. LG has discontinued the 84TR3B, so the manufacturer no longer offers it as a new product. SmartRooms Qatar can quote a current equivalent with a similar 84-inch size, multi-touch capability and connection set, or a compatible replacement for your room. Send your room dimensions, the sources you use and whether the existing board is still working, and quotations are usually returned within one working day.

Which rooms in Qatar suit an 84-inch LG 84TR3B?

It suits rooms where a group needs one large shared screen, such as a lecture hall in Education City or a boardroom in Msheireb. Before choosing it, measure the distance from the furthest seat to the screen, since an 84-inch panel is intended for larger rooms than a smaller 65-inch screen. SmartRooms Qatar can help you check the viewing distance as part of the quotation process.

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

The board recognises up to 10 simultaneous touches, so up to ten points of contact can register at once. Basic writing and drawing work with hands, and two touch pens are included with the board. In a classroom in Al Sadd, several students can work through the same problem on the screen at the same time, which suits group tasks.

Will the protection glass reduce brightness in a bright lobby?

Yes, according to the manufacturer data. Typical brightness is 350 cd/m², and it drops to 300 cd/m² when the protection glass is fitted. A reception lobby in West Bay with large windows gets strong daylight, so ask the SmartRooms Qatar team to review the placement and glass arrangement before ordering. The data gives no operating temperature range, so confirm the environment too.

Which inputs does it have, and does it accept analogue RGB?

It has two HDMI inputs, one DisplayPort, one DVI-D, one component input and an audio input, plus one USB 3.0 and two USB 2.0 ports. The source data lists no analogue RGB input, so an older laptop that only outputs VGA cannot connect directly without a different source. Check your source ports before ordering. An external media player cannot be attached, although the MP700 and MP500 are listed as optional media players.

Does it work with SuperSign digital signage software?

The data lists SuperSign-w lite as compatible and SuperSign-c as not compatible. If you plan to run a notice display in a school corridor or a government reception, decide on the signage platform before buying, and the SmartRooms Qatar team can check your setup against this compatibility list. The board also provides RS232C and LAN control ports for external control.

Can a boardroom in Msheireb mount this board on an existing wall?

Only after the wall and bracket are checked. The head weighs 104.0 kg, and the VESA pattern is 600 x 400 mm with M8 holes, so the bracket must match that pattern and the wall must carry the load. SmartRooms Qatar offers a free site survey before wall-mounting, which lets the team check the wall before any mounting work is booked. Two eye-bolt assemblies are supplied with the board.

What mounting pattern and clearance does it need?

The VESA standard mount interface is 600 x 400 mm with M8 holes. Confirm that any wall bracket or floor stand you choose lists the same pattern before ordering. When planning clearance, check the monitor dimensions of 1,951.2 mm wide, 1,137.2 mm high and 111.9 mm deep, along with the 34.0 mm bezel, so the panel sits correctly against the wall.

What comes in the box with the board?

The listed accessories are a power cord, a remote controller with two batteries, an IR/light sensor receiver, a USB 2.0 cable, an HDMI 2.0 cable, a DisplayPort cable, two cable ties, two touch pens, a pen tray, two eye-bolt assemblies and a screw package. The external speaker SP-2100 is listed as an optional extra. Ask the SmartRooms Qatar team to confirm the included items in your quotation.

Can a school in Al Khor buy several boards on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, and payment can be made by bank transfer, cheque or purchase order. Because each board weighs 104.0 kg, a school fitting out several classrooms should plan wall checks and delivery access in advance. Send the quantities, the room list and your LPO reference when requesting a quote.

Is it suitable for a hotel conference room in Lusail?

It can suit a workshop room where a presenter writes and annotates directly on the screen with up to 10 simultaneous touches. The data gives 350 cd/m² typical brightness and 300 cd/m² with protection glass. It does not give an operating temperature or an environment rating, so ask the SmartRooms Qatar team to confirm room conditions and lighting before ordering. If you need a fresh board, ask about a current equivalent.
