Brand: LG
SKU: lg-55tr3bg
Availability: Discontinued

Overview

The LG Createboard 55TR3BG is a 55-inch interactive digital board with a UHD IPS panel, 20-point multi-touch, a built-in OPS slot and Android 8 on board. It suits classrooms and meeting rooms that need shared writing and screen sharing from laptops and mobile devices. LG has discontinued this model, so ask SmartRooms Qatar for a quotation on a current equivalent or a compatible replacement.

What the LG Createboard 55TR3BG is

The LG Createboard 55TR3BG is a 55-inch interactive digital board built around a UHD IPS panel with a native resolution of 3840 x 2160. It runs Android 8 on an internal processor, so teachers and presenters can browse the web, annotate and open apps without bringing in a separate computer. LG has discontinued this model. This page is written for organisations that already run it, for buyers comparing it with newer boards, and for anyone who needs a replacement.

Touch, writing and annotation

The touch layer handles up to 20 simultaneous points, with stated accuracy of ±1.5 mm and detection of objects from Ø3 mm. Several people can write or drag at the same time, which suits group problem solving at the board. Annotation supports undo and redo and works over any source. Touch connects by USB 2.0 and is listed for Windows, Linux, Mac and Android, although Windows XP, Linux and Mac operate with single-point touch only.

Display and connectivity for Qatar classrooms and meeting rooms

The panel offers 1.07 billion colours, a 1,200:1 contrast ratio and 310 nit typical brightness without the protective glass, with a viewing angle of 178° horizontal and vertical. The 3 mm anti-glare glass has 25% haze. The specified refresh rate is 60 Hz and the grey-to-grey response time is 8 ms. The panel is supported in landscape orientation only.

Inputs include three HDMI ports, an RGB input, audio in and out, one RJ45 LAN port, RS232C control, three USB 3.0 Type A ports and three USB 2.0 Type A ports, plus two USB 2.0 Type B touch connections. A built-in OPS slot takes an OPS computer module at the back of the board, and Wi-Fi (802.11a/b/g/n/ac), Bluetooth 4.0 and Gigabit LAN are built in. The on-screen menu language list includes Arabic (Egypt) alongside English.

Where it fits in Qatar

Primary classroom in Al Wakrah: a private school refitting a classroom can use the Air Class feature, which supports up to 30 students on the same network for voting, answering and sharing project text from their own devices.
Training centre in the Industrial Area: instructors can show up to six shared screens at once with ScreenShare Pro, which is useful when several trainees bring laptops to a practical session.
Bilingual office in Msheireb: a ministry or company meeting room can pair the board with Bluetooth speakers or a keyboard and use the Arabic (Egypt) menu option for staff who prefer it.

Power, heat and room planning

The built-in power supply is rated at AC 100-240 V, 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical draw is 125 W, maximum 259 W and 0.5 W in power-off. Display Power Management can keep the screen on only when an input signal is present. The operating temperature range is 0 °C to 40 °C at 10% to 80% humidity. Qatar summer temperatures regularly exceed 45 °C, so install the board only in air-conditioned rooms and keep it away from sunlit windows and open entrances.

The head weighs 27 kg, the packed weight is 45.7 kg and the monitor measures 1271 x 774 x 84 mm. The VESA mounting pattern is 400 x 200 mm. The accessory list does not include a wall mount, so confirm mounting hardware in your quotation. Our free site survey checks wall strength, cable routes and mounting height before installation. Check that the 3 m power cord's plug suits BS 1363 sockets.

Replacement and next steps

Because LG has discontinued the 55TR3BG, organisations that already own units, and buyers who want the same format, should request a quotation for a current 55-inch equivalent or a compatible replacement. Send your room size, mounting plan, number of connected devices and the variant codes you have seen (55TR3BG-B.AMAQ or 55TR3BG-B.AMIQ). Our team usually returns a quotation within one working day. Request a quote today and we will confirm the best match for your room.

Questions about 55TR3BG

Is the LG 55TR3BG still available to order?

LG has discontinued the 55TR3BG, so the most practical step is a quotation for a current equivalent. SmartRooms Qatar can price a 55-inch replacement that matches this model's UHD resolution, 20-point touch and built-in OPS slot. We can also check compatibility with your existing mounts and cabling before you decide.

We already own this board. What should we check before deciding to replace it?

Check whether the Android 8 platform with 3GB RAM and 16GB storage still runs your apps. Confirm your operating systems: the touch driver lists Windows, Linux, Mac and Android, but Windows XP, Linux and Mac support single-point touch only. If these limits affect your lessons or meetings, request a quotation for a replacement.

What is the LG 55TR3BG used for?

It is a 55-inch interactive digital board for classrooms, training rooms and small to medium meeting rooms. Its 20-point touch allows several people to write at once, and its built-in Android platform lets presenters browse the web and annotate without a separate PC. It suits spaces that use the board as the main display rather than a secondary screen.

Does the board work with Qatar's 240 V mains supply?

Yes, the built-in power supply is rated AC 100-240 V, 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. The supplied 3 m power cord's plug should be checked against BS 1363 (Type G) sockets in your room before installation. Our team can confirm this detail in the quotation.

How much power does the 55TR3BG draw?

The specified typical draw is 125 W and the maximum is 259 W, with 0.5 W in power-off mode. Display Power Management can keep the screen on only when an input signal is present, which helps reduce idle use. For planning, compare these figures with your existing displays when you request a quotation.

Can we use it outdoors, or near a sunlit window in a hot hall?

No, the operating temperature range is 0 °C to 40 °C at 10% to 80% humidity, which is below Qatar summer temperatures that regularly exceed 45 °C. Install it in an air-conditioned room and keep it away from direct sunlight and open entrances, where dust and heat can build up.

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

The touch layer supports up to 20 simultaneous points, with stated accuracy of ±1.5 mm and detection of objects from Ø3 mm. This suits group problem solving, where several students or staff members annotate, drag or mark up content together. Windows XP, Linux and Mac operate with one-point touch only.

Can students connect their own devices during a lesson?

Yes. The Air Class feature supports up to 30 students on the same network, with voting, answering and sharing of project text from mobile devices. ScreenShare Pro can display up to six shared screens or a file in real time. These functions suit a classroom where pupils work on tablets or phones alongside the board.

Does the menu support Arabic, and can staff use both languages in one room?

The on-screen menu language list includes Arabic (Egypt) alongside English and many other languages. Offices in Doha that work in Arabic and English can set the menu to the language their staff prefer. Confirm the exact language set for your installation in the quotation.

Can it be wall-mounted, and what space does it need?

The VESA pattern is 400 x 200 mm, the head weighs 27 kg and the monitor measures 1271 x 774 x 84 mm. The accessory list does not include a wall mount, so mounting hardware should be confirmed in the quotation. A free site survey checks wall strength, mounting height and cable routes before installation.

Which devices can I connect to the board?

The board has three HDMI inputs, an RGB input, audio in and out, one RJ45 LAN port, RS232C control, three USB 3.0 Type A and three USB 2.0 Type A ports. A built-in OPS slot accepts an OPS computer module. Wi-Fi (802.11a/b/g/n/ac), Bluetooth 4.0 and Gigabit LAN are also built in for wireless and wired connections.

Which certifications does the 55TR3BG carry for a government tender?

The listed certifications are FCC Class A, CE for EMC, and CB or NRTL for safety. ERP is listed as yes and Energy Star as no. When the purchase goes through a government tender or Monaqasat, SmartRooms Qatar can prepare the quotation and issue an LPO for the approved units.
