DS-D5B75RB/EL

A 75-inch 4K board for teaching and collaborative meetings

The Hikvision DS-D5B75RB/EL is a 75-inch interactive display from the WonderHub Value Series. Its 16:9 screen covers a display area of 1650.24 mm by 928.76 mm and renders 3840 × 2160 pixels at 60 Hz, so slides, spreadsheets and handwritten notes stay crisp when viewed up close. It suits rooms where several people write, annotate and share from the same wall, rather than one presenter working from a laptop.

Picture quality and touch performance

The IPS panel is rated at 400 cd/m² typical brightness with a 1200:1 static contrast ratio, and its 178° horizontal and vertical viewing angles keep colours readable for people seated at the sides of the room. The 3.2 mm anti-glare glass with 25% haze reduces reflections from ceiling lights and windows. The infrared touch layer tracks up to 40 points at once, responds within 5 ms, detects objects from 2 mm, and holds touch precision of ±1 mm across at least 90% of the touching area. Two styluses are included in the box.

Software, ports and sound

Android 13 runs on a quad-core Cortex-A55 processor at 1.92 GHz, with 8 GB memory and 64 GB built-in storage. For a Windows environment, the optional OPS module measuring 195 × 30 × 180 mm adds a second system, and the manufacturer recommends running video conferencing software on Windows. Inputs include two HDMI 2.0 ports and one audio input, with one audio output, a TOUCH-USB 2.0 port and an RS232 control port. Three USB 3.0 ports, two USB 2.0 ports and a Type-C port (USB 2.0 only) handle peripherals. Two 100 Mbps LAN ports sit alongside Wi-Fi on 2.4 GHz and 5 GHz, and the built-in speakers are rated 2 × 20 W. The unit has no built-in camera or microphone, so video calls need separate devices.

Where this model fits in Qatar

• A classroom in a private school: a school in Al Wakrah fitting out a mid-sized classroom can use the 75-inch surface for lessons, with the touch layer letting students work through problems at the board.
• A training centre meeting room: a training provider in the Industrial Area or Msheireb can run workshops where several trainees write on the screen at once, using up to 40 touch points.
• A corporate or government boardroom: an office in West Bay or Lusail can show a laptop screen through HDMI for meetings, with a separate camera and microphone added for calls with teams abroad.

Planning the installation and power

The panel weighs 49.15 kg net and 63.0 kg gross, so the wall or structure must be checked before fixing. The VESA pattern is 800 × 400 mm with four M8 fixing points, and a wall mount bracket is supplied. A free site survey lets our team check the wall, the bracket position and cable routes before installation day. The operating range is 0 °C to 40 °C at 10% to 90% relative humidity, and summer temperatures in Qatar can pass 45 °C, so the panel belongs in an air-conditioned room, away from direct sun and hot window glare. Rated input is 100 to 240 VAC at 50/60 Hz, averaging 175 W and peaking at 217 W. The supplied 1.5 m power cable is the European standard type, so confirm the plug arrangement against BS 1363 sockets before ordering.
