It runs on 8 GB RAM and 128 GB storage, with Wi-Fi 6, Bluetooth 5.4, a 16-microphone array and 4 speakers. Built for lecture halls and boardrooms in Qatar's schools, universities and offices, it is sold by quotation from SmartRooms Qatar.

An 86-inch board with its own Android 15 computer

The LPH86-ST480-U-S2 pairs a large 4K LCD panel with a built-in Android 15 system, so a lesson or meeting can start straight from the board. The processor runs at 2.4 GHz and the unit includes 8 GB of memory and 128 GB of storage. It belongs to Dahua's ST480 Series within the Education Series, and it ships with a remote control and two stylus pens.

Display and touch figures that matter day to day

3840 × 2160 resolution on a 16:9 DLED panel refreshing at 60 Hz
400 cd/m² typical brightness with a 1200:1 typical static contrast ratio
Infrared touch with a zero air gap, covering over 90% of the screen
64 touch points on both Android and Windows
3.2 mm anti-glare tempered glass with a surface hardness of 9H or higher

Brightness and contrast are typical values, not guarantees for every room, so test the board in the actual space where possible. The anti-glare glass reduces reflections from ceiling lights, but a window behind the presenter will still wash out the picture. Position the panel away from direct sun and check the lighting before fixing it to the wall.

Connections for teachers, presenters and visiting devices

The front panel offers an HDMI input, two USB 3.2 Gen1 Type-A ports and a USB-C input rated for 100 W fast charging, which also carries data and network traffic for bring-your-own-device use. The rear panel adds three HDMI inputs and an HDMI output, a DisplayPort input, a 4K USB-C output, VGA, audio line in and out, S/PDIF, RS232 and two gigabit RJ45 ports. Wi-Fi 6 in dual-band mode, Bluetooth 5.4 and NFC quick unlock complete the wireless set, and a microSD slot expands storage up to 512 GB.

Where it fits in Qatar

In a private school in Al Rayyan refitting its classrooms, one unit on the front wall lets teachers move between Arabic and English materials on one surface, while the 16-microphone array with a pick-up distance of up to 12 m captures student questions from the back of the room. In a boardroom in West Bay or Msheireb, the 86-inch screen shows documents to a full table, and a laptop can be connected through HDMI or USB-C. A seminar room in Education City or a training centre in the Industrial Area can use the same surface for group work, with pen input and palm rejection supporting hands-on problem solving.

Planning the installation

The board weighs 58.6 kg net and 73.5 kg with packaging, and its dimensions are 1,914.9 mm by 116.2 mm by 1,177.2 mm. Wall mounting uses rear holes spaced 800 mm by 400 mm, and the kit includes a wall mount bracket and screw pack; a mobile bracket is also an option. Because of its weight, we recommend a free site survey to check the wall, the cable route and the power point before the unit arrives. The operating range is 0 °C to +40 °C with 10% to 90% non-condensing humidity, so the room must be air-conditioned, since Qatar summer temperatures can exceed 45 °C. Power draw is 130 W typical and 390 W maximum, and the supply accepts 100 to 240 VAC at 50 or 60 Hz.

Questions about LPH86-ST480-U-S2

Who is the LPH86-ST480-U-S2 best suited to?

It suits classrooms, lecture rooms and boardrooms that need one large display surface for teaching or presenting. At 86 inches with a 3840 × 2160 panel, it works for groups of a reasonable size, such as a training room in the Industrial Area. Smaller meeting rooms may suit a smaller screen better, so compare the room layout with the screen size before choosing.

Can it be used without a laptop, and does it run Windows software?

Yes. The built-in Android 15 system, with 8 GB RAM and 128 GB storage, runs content and apps directly on the panel. Windows is handled through the external module, which supports Windows 7, 8, 10 and 11, and a wireless plug-in module is included. Confirm the software your team needs before ordering, so the right setup is quoted.

What ports are available for connecting a laptop or visitor device?

The front of the board has one HDMI input, two USB 3.2 Gen1 Type-A ports and a USB-C input with 100 W fast charge, data transfer and network support for bring-your-own-device use. The rear adds three HDMI inputs, a DisplayPort input, a USB-C output and VGA, plus RS232 and two RJ45 ports for wired networking. Wi-Fi 6 and Bluetooth 5.4 are also built in.

How does the touch and pen writing work?

Touch uses infrared technology with a zero air gap design, and the valid touch zone covers over 90% of the screen. The board supports 64 touch points on Android and on Windows, with finger and pen input. Two stylus pens are included, and palm rejection and palm erasing help when writing with a hand resting on the glass.

Can it be installed in a hall without air conditioning?

It should not be. The operating range is 0 °C to +40 °C with 10% to 90% non-condensing humidity, while summer temperatures in Qatar can exceed 45 °C. Install it in an air-conditioned room, away from windows and direct sun. The storage range of −20 °C to +60 °C applies only when the unit is kept in store before installation.

Will it work with Qatar's 240 V power supply?

The power supply accepts 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 130 W and maximum is 390 W, with standby below 0.5 W. The package includes a power cord, and an electrician should confirm the socket and cord fit at the mounting position before installation.

How heavy is it, and what does wall mounting require?

Net weight is 58.6 kg and gross weight with packaging is 73.5 kg, so the wall and fixing points need checking first. The rear mounting holes are spaced 800 mm by 400 mm, and the kit includes a wall mount bracket and screw pack. A mobile bracket is also an option. SmartRooms Qatar offers a free site survey before installation, which we recommend for a panel of this size and weight.

How could a school in Al Rayyan use it in a classroom refit?

A school refitting classrooms in Al Rayyan could mount one panel on the front wall, where its 3840 × 2160 resolution keeps Arabic and English text clear for students in the back rows. The microphone array, with pick-up up to 12 m, captures questions without a handheld microphone. Plan the power point and cable routing before the installation day.

How does it suit a boardroom in West Bay or Msheireb?

In a boardroom in West Bay or Msheireb, the 86-inch screen shows slides and shared documents clearly to everyone around the table. Its 178° horizontal and vertical viewing angles keep text readable from the side of the room, and touch lets the presenter annotate directly. Connect a laptop over HDMI or USB-C, and check the cable route during the site survey.

Is it suitable for a university lecture room in Education City?

It suits seminar rooms and mid-sized lecture rooms in Education City more than very large tiered halls, which often need more than one screen. The 16-microphone array with echo cancellation helps capture questions from back rows. Compare the room dimensions with the screen size before requesting a quote.

Can a school or government entity order it through an LPO or tender?

Yes. SmartRooms Qatar supplies this board to all eight municipalities of Qatar and accepts purchase orders (LPOs) and government tenders, including those published on Monaqasat. Payment can be made by bank transfer, cheque or purchase order. Send the quantity, room list and mounting details, and we will return a quotation, usually within one working day.
