What the 55TR3DK is built to do in a classroom or meeting room

The LG CreateBoard 55TR3DK is a 55-inch interactive board with a UHD IPS panel at 3840 x 2160 resolution. It combines the touch surface, an Android 11 system and a set of teaching tools in one unit, so a teacher or presenter does not need a separate PC to write, annotate or share material. The 16:9 aspect ratio suits slides and spreadsheets, although the panel cannot be used in portrait orientation.

The specifications that matter when you compare boards

Touch: up to 40 simultaneous points on Windows and 32 on Android, with typical accuracy of ±1 mm and a 3 mm anti-glare protection glass.
Image: 390 nit typical brightness without the glass, a 1,200:1 contrast ratio, an 8 ms response time (G to G) and a 60 Hz refresh rate.
Connectivity: three HDMI inputs, a USB-C port, four USB 3.0 Type A ports, two USB 2.0 Type B touch connections, an RJ45 LAN port and an RS232C input.
Computing: quad-core processor, 4 GB RAM, 32 GB storage, Wi-Fi 6 (802.11a/b/g/n/ac/ax), Bluetooth 5.0 and Gigabit LAN.
Sound: built-in speakers rated 15 W x 2.

Teaching, sharing and remote management

Built-in teaching templates include a ruler, a table and sticky notes, and the QR code on the home screen signs users into Google Drive or OneDrive without a separate login. Up to nine shared screens can be displayed wirelessly when the CreateBoard Share app is installed, and devices on the same network can share without it, although the dedicated app gives a steadier connection. Smart Viewing shows two sources side by side or one over the other. LG ConnectedCare DMS is a cloud tool for monitoring and managing boards remotely, and it is sold separately.

Where it fits in Qatar

A private school in Al Wakrah fitting out primary classrooms can use the 55-inch size in rooms of modest depth, where the front ports and speakers are easy for teachers to reach. A government office in Msheireb might place one in a smaller meeting room for team presentations. A training centre in Education City running short workshops can use Bluetooth to connect a keyboard or speaker, and Wi-Fi 6 to handle sessions that link Doha with colleagues abroad.

What to plan before ordering

The head weighs 26.1 kg and 34.5 kg packed, with monitor dimensions of 1271 x 774 x 87 mm. The VESA interface is 400 x 200 mm, and the wall mount WM-L000S and floor stands ST-000F and ST-860F are optional. The operating range is 0 °C to 40 °C at 10% to 90% humidity. Summer temperatures in Qatar can exceed 45 °C, so install the board in an air-conditioned room away from direct sunlight through windows. Typical power draw is 170 W, with a maximum of 395 W. Because the board is heavy, SmartRooms Qatar offers a free site survey before wall mounting, and we deliver to all 8 municipalities of Qatar. Organisations buying through a purchase order (LPO) or a government tender can request a quote, and our team usually responds within one working day.

Request a quote from SmartRooms Qatar for the LG CreateBoard 55TR3DK, and tell us the room, the number of units and whether you need a wall mount or a floor stand.

Questions about 55TR3DK

Who should buy the LG CreateBoard 55TR3DK?

The LG CreateBoard 55TR3DK is a 55-inch interactive board that combines a UHD touch display with a built-in Android 11 system, so teachers and presenters can write, annotate and share without bringing a separate PC. It suits primary and secondary classrooms, training rooms and smaller meeting rooms in Qatar where one board must handle lessons, presentations and wireless sharing.

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

The board detects up to 40 simultaneous touch points on Windows and up to 32 on Android. The specifications note that Linux and Mac connections support one-point touch only. Touch accuracy is typically ±1 mm, and the 3 mm anti-glare protection glass helps keep handwriting precise when several students work at the board during a class.

Will it work in a Doha meeting room with large windows?

The panel is rated at 390 nit typical brightness without the protective glass, with a 1,200:1 contrast ratio and a 25% haze surface treatment that reduces reflections. These figures suit rooms with controlled daylight. If your meeting room has large windows or faces the afternoon sun, we recommend a site survey so the board can be positioned away from direct glare before you order.

Can I connect a laptop, a document camera or a video conferencing system?

The board has three HDMI inputs, an RGB input, a USB-C port, four USB 3.0 Type A ports, one USB 2.0 Type A port, audio in and out, and an HDMI output. A laptop can connect by HDMI or USB-C. Connecting a camera or conferencing codec depends on its outputs, so confirm your equipment with the SmartRooms Qatar team before ordering.

What is the OPS slot for, and which computers fit it?

The built-in OPS slot lets you mount an OPS computer at the back of the board, so you do not need an external desktop cabled to the display. The specifications list built-in OPS power, so the slot supplies power to the module. Check the module size and standard before ordering, and ask our team to confirm compatibility with the OPS computer you plan to use.

Can I save and import files from Google Drive, OneDrive or USB storage?

Yes. Resources can be saved to and imported from Google Drive or OneDrive, and files can be imported from a USB drive. The QR code on the home screen lets users verify their personal device and sign into these cloud apps with one verification. Logging out at the end of a lesson disconnects the account, which reduces the risk of personal information being left on the board.

How does wireless sharing work when several laptops join a meeting?

With the CreateBoard Share app installed, up to nine shared screens can be shown on the board in real time, and the host can send files to connected devices. Devices on the same network can also share without the app, but the specifications recommend the dedicated app for a more stable connection. Wi-Fi 6 and Bluetooth 5.0 are built in.

Can one IT team manage boards across several school sites in Doha and Al Khor?

LG ConnectedCare DMS is a cloud solution for monitoring and controlling boards remotely. It can schedule power on and off, adjust brightness, lock the screen, send alert messages and set thresholds across eight categories, including display temperature and memory usage. It is sold separately and supports the TR3DK series. Availability depends on region, so ask SmartRooms Qatar to confirm it for your sites.

Is the board compatible with Qatar's 240 V mains supply?

The power supply is rated at AC 100-240 V, 50/60 Hz, and the power is built in, so the board is designed for a wide input range. Qatar mains supply of 240 V at 50 Hz falls within that rating. Typical consumption is 170 W, the maximum is 395 W and power-off draw is 0.5 W. Confirm the plug and socket arrangement with our team when you request a quote.

Can it be wall mounted in a boardroom in West Bay, and what space does it need?

The VESA mounting interface is 400 x 200 mm, and the monitor measures 1271 x 774 x 87 mm, with a head weight of 26.1 kg and a packed weight of 34.5 kg. The wall mount WM-L000S and floor stands ST-000F and ST-860F are optional. Because the board is heavy, we offer a free site survey to check wall construction and clearance before installation.

What comes in the box, and is a remote control included?

The box includes a 3 m power cord, a 5 m USB cable (Type A to Type B) for touch, a 3 m HDMI cable, two writing pens, a remote controller with two batteries, a Wi-Fi module, the user manual and a quick start guide. The remote handles power on and off, scheduling, brightness and screen lock. USB Type C cables are sold separately.

Is this a suitable choice for a school in Lusail ordering several classrooms?

For a school equipping several classrooms, the 55-inch size and a shared feature set make it easier to standardise rooms and training. SmartRooms Qatar can quote the boards together with the mounts or stands you need. Orders from schools and government bodies can be placed by purchase order (LPO) or through a tender, and our team usually responds with a quotation within one working day.
