What the Dahua LPH75-ST430 Is
The Dahua LPH75-ST430 is a 75-inch interactive whiteboard designed for teaching spaces. It pairs a 4K display with a built-in Android computer, so lessons can run from the panel itself without a separate PC. It belongs to the ST430 Education Series, and its 16:9 screen has a resolution of 3840 × 2160.
Performance, Display and Touch Facts That Matter
Inside the frame sits a quad-core Cortex-A73 processor running at 1.5 GHz, with a Mali G52MC1 graphics unit, 8 GB of RAM and 128 GB of storage. The operating system is Android 14. The LCD uses DLED backlighting rated at 400 cd/m² typical, with a 60 Hz refresh rate, an 8 ms response time, a lifespan of at least 50,000 hours and 72% NTSC colour coverage.
The infrared touch layer is attached with a zero air gap, and the front is 4 mm anti-glare tempered glass rated 9H or harder. Touch accuracy is ±1.5 mm, and the system registers 32 touch points on Android and 40 on Windows. Writing works with fingers and with the magnetic stylus supplied in the box.
Connectivity for Teaching and Meetings
- Three HDMI IN ports: two at the rear and one at the front, each supporting 4K at 60 Hz.
- Two USB Touch Type-B 2.0 ports, one at the front and one at the rear, for touch data.
- Front USB 2.0 Type-A ports (switchable), a rear USB 3.2 Gen1 Type-A port, and a front Type-C port for data with 5 V 1 A charging.
- Wi-Fi supporting 802.11 a/b/g/n/ac/ax and Bluetooth 5.4.
- A wired RJ-45 port rated 10/100 Mbps, plus RS-232, MIC IN, LINE OUT, OPTICAL and an OPS port.
Where It Fits in Qatar
In a primary or secondary classroom in Doha, Al Rayyan or Al Wakrah, a 75-inch panel keeps lesson content readable from the back row, and its two 20 W speakers provide audio suited to a classroom-sized room.
At a training centre in Education City or Lusail, trainers can open Chrome and YouTube directly on the screen, or connect an external computer through HDMI or USB. In a meeting room in West Bay or The Pearl, a laptop can be shared over HDMI and annotated during a call using the stylus or a finger.
Planning the Installation and Environment
At 1,707.5 mm wide, 116.7 mm deep and 1,041.9 mm tall, with a net weight of 47.5 kg (58 kg gross), the panel needs two people to lift and a wall that can carry its weight. The rear mounting holes are spaced 600 mm by 400 mm, and the packing list includes a wall mount bracket and a screw pack. A free site survey lets our team check wall construction, outlet position and sightlines before anything is fixed.
Power input is 100–240 VAC at 50/60 Hz, which covers Qatar's 240 V mains supply. Typical consumption is 178 W and maximum is 280 W. The operating range is 0 °C to +40 °C with 10% to 90% humidity. Qatar summers can exceed 45 °C, so install the panel in an air-conditioned room away from windows and direct sunlight, and confirm the room conditions with the SmartRooms Qatar team before installation.
