Overview

The Dahua LPH75-ST480-U-S2 is a 75-inch smart interactive whiteboard from the ST480 Education Series. It pairs a 4K panel with a 64-point infrared touchscreen, runs Android 15 with 8 GB RAM, and includes a 16-array microphone and 2 × 10 W + 2 × 20 W speakers. Suited to classrooms and training rooms in Doha, Al Rayyan and Lusail that need one self-contained teaching display.

What the LPH75-ST480-U-S2 does

The LPH75-ST480-U-S2 is a 75-inch interactive whiteboard from Dahua's ST480 Education Series. It combines a 3840 × 2160 DLED panel with an infrared touch layer and an on-board Android 15 system, so a teacher can annotate, open lesson files and run apps from the glass itself. The panel is rated at 400 cd/m² typical brightness and 1500:1 typical static contrast, with an 8 ms response time and a lifespan of at least 50,000 hours.

Touch, writing and display quality

The touchscreen supports 64 touch points on both Android and Windows, with a response time of 1.67 ms or less and anti-dazzle tempered glass rated at 9H or harder. Two styluses come in the box, and the pen attaches magnetically to the frame. Palm erasing and palm rejection are listed, so a presenter can rest a hand on the surface while writing. The 10-bit panel shows 1.07 billion colours across a 90% NTSC gamut, which helps diagrams and maps keep their detail.

Connectivity, sound and power

The front panel offers one HDMI input, two USB 3.2 Gen1 Type-A ports and a USB Type-C input rated for 100 W fast charge, data and LAN, which suits bring-your-own-device sessions. The rear panel adds three 4K HDMI inputs and one 4K HDMI output, a DisplayPort input, VGA, RS232, 10/100/1000 Mbps RJ45 ports and a microSD slot expandable to 512 GB. Wi-Fi 6 and Bluetooth 5.4 are built in, and the 16-array microphone picks up voices up to 12 metres away. The power supply is rated 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V supply. Typical draw is 110 W, rising to 330 W at maximum.

Where it fits in Qatar

  • Primary and secondary classrooms in Al Wakrah or Al Rayyan, where one large display can replace a projector and screen.
  • Training rooms at Education City, where lecturers connect over Wi-Fi 6 and use the microphone to reach the back of the room.
  • Boardrooms in West Bay or Msheireb, where the HDMI output passes the picture on to a second 4K display at 60 Hz.

What to plan before installation

The board measures 1,668.7 mm wide, 1,038.5 mm high and 116.2 mm thick, and weighs 44.6 kg net or 56.8 kg packed, so a lifting plan and a structurally sound wall are essential. The wall-mount holes are 600 mm by 400 mm, and the box includes a wall-mount bracket and screw pack. The data also lists a mobile bracket as an installation option. The operating range is 0 °C to +40 °C at 10–90% humidity, non-condensing. Qatar summer temperatures can exceed 45 °C, so the board belongs in air-conditioned rooms, not open halls or outdoor areas. A free site survey from SmartRooms Qatar checks wall strength, cable routes and bracket type before delivery.

Questions about LPH75-ST480-U-S2

Who is the LPH75-ST480-U-S2 best suited to?
It suits teaching and collaboration rooms that need one large touch display. In Qatar, that means primary and secondary classrooms in Al Wakrah or Al Rayyan, training rooms at Education City and university seminar rooms. The 75-inch 4K panel and 64-point touch let a whole class read and write on the board from the back of the room.
What resolution and brightness does the panel offer?
The panel is a 16:9 DLED display with a 3840 × 2160 resolution, 400 cd/m² typical brightness and 1500:1 typical static contrast. Viewing angle is rated at 178° horizontally and vertically, so content stays readable from the sides of a room. The 8 ms response time and 60 Hz refresh rate are listed, and the lifespan is rated at 50,000 hours or more.
Does the board need a separate computer to run lessons?
The board runs Android 15 on a quad-core A76 plus quad-core A55 processor at 2.4 GHz, with 8 GB RAM and 128 GB storage, so it can run apps on its own. The source also lists an external module that supports Windows 7, 8, 10 and 11, and the packing list includes a wireless plug-in module. Confirm with SmartRooms Qatar which Windows setup you need before ordering.
How many touch points does it support, and what writing tools come in the box?
The touchscreen supports 64 touch points on Android and on Windows, using infrared touch with a zero air gap attachment. The box includes two stylus pens, and the pen attaches magnetically to the frame. Listed functions include dual-colour pen writing, finger dragging, multi-touch, palm erasing and palm rejection. Valid touch is rated at 1.5 mm across more than 90% of the touch area.
How does a teacher in a Doha classroom use the front ports during a lesson?
The front has one HDMI input, two USB 3.2 Gen1 Type-A ports, a USB Type-C input rated at 100 W fast charge with data and LAN, and a touch USB 2.0 Type-B port. Front buttons cover volume, input selection, home, power, touch lock and curtain control. A teacher can plug in a laptop at the start of a lesson without reaching behind the board.
Can a West Bay boardroom feed a second display from this board?
Yes. The rear panel has one HDMI output rated at 4K and 60 Hz, which can pass the picture to a second display. The rear also includes a USB Type-C output at 4K 60 Hz, three HDMI inputs and a DisplayPort input. The source does not list a camera, so confirm any separate conferencing camera with SmartRooms Qatar before you buy.
Will it cope with summer heat in an unconditioned hall?
No, it should not be used there. The operating range is 0 °C to +40 °C, with 10–90% humidity, non-condensing. Summer temperatures in Qatar can exceed 45 °C, so the board belongs in air-conditioned rooms, not open halls, sun-exposed lobbies or outdoor areas. Storage is rated −20 °C to +60 °C. Ask the SmartRooms Qatar team to check room cooling during the site survey.
Is the power supply compatible with Qatar's 240 V mains?
The power supply is rated 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 110 W, rising to 330 W at maximum, and standby is 0.5 W or less. The packing list includes a power cord. Check its plug type with SmartRooms Qatar before ordering so the cord matches the sockets in your room.
Will it fit a Lusail office wall, and how heavy is it?
The board weighs 44.6 kg net and 56.8 kg packed, and measures 1,668.7 mm wide, 1,038.5 mm high and 116.2 mm thick. The wall-mount holes are 600 mm by 400 mm, and the box includes a wall-mount bracket and screw pack. Installation is by wall mount or mobile bracket. A free site survey checks wall strength and bracket fit before the unit is delivered to the office.
Are Wi-Fi 6 and Bluetooth enough for a training centre in Education City?
The board has Wi-Fi 6 with one station and one access point mode, on 2.4 GHz and 5 GHz bands, plus Bluetooth 5.4. NFC supports quick unlock. The source lists a 13.56 MHz RFID reader but does not describe its use, so check the intended application with SmartRooms Qatar. Real-world coverage depends on your network, so the IT team should test signal strength in the training room.
How should a school order several boards with an LPO?
Send your room list, wall types and quantity, and SmartRooms Qatar will return one quotation, usually within one working day. Purchase orders (LPOs) are accepted, along with government tenders, and payment can be made by bank transfer, cheque or purchase order. Delivery covers all eight municipalities of Qatar, and professional installation can be included in the quotation.
