PMB528L552

A 55-inch 4K MultiBoard with a detachable PC

The Prestigio PMB528L552 is part of the MultiBoard L-Series, pairing a 55-inch LED display with a detachable PC module. The panel resolves 3840x2160 at 60Hz, which keeps spreadsheets, diagrams and small text readable at the distances typical of a classroom or meeting room. The manufacturer has discontinued this model, so this page is written for organisations that already own one, buyers comparing it with newer boards, and anyone who needs a replacement.

Display and touch figures that matter in use

The screen is rated at 350 cd/m² brightness and a 1,200:1 contrast ratio, with an 8 ms maximum response time and 178° horizontal and vertical viewing angles. The 4 mm tempered glass surface carries a Mohs level 7 rating, and the infrared touch system supports 20 touch points and 10 writing points. The dot pitch is 0.315 mm, and the panel life is rated at 30,000 hours.

Computing built into the frame

The detachable PC module uses an Intel Core i5-8400 processor running at 2.8 GHz, with 8GB of DDR4 memory, a 256 GB SSD, an Nvidia GeForce GT 1030 graphics card and an Intel H310 chipset. Windows 10 Pro is the main operating system, and the board also includes an Android 8.0 system with an ARM dual-core CPU, 3GB of RAM and 16GB of internal storage. Wireless connection is 802.11ac Wi-Fi 5 with two antennas, Bluetooth 4.2 is included, and a 10/100/1000M LAN port is provided.

Ports, accessories and what arrives in the box

On the display side there are three HDMI inputs, one VGA port, an RS-232 serial port, an S/PDIF output, 13 USB ports, a LAN port and audio line-in and line-out sockets. The PC module adds its own DisplayPort, HDMI output, VGA port, LAN port, microphone input and line-out. The package includes a remote control, six writing pens and one multi pen, a USB install stick, two Wi-Fi antennas, and AC power, audio, USB, HDMI and VGA cables.

Where this model fits in Qatar

Three situations suit this board:

• A secondary school in Al Wakrah replacing an older board in a 55-inch classroom, where the built-in Windows PC lets teachers run lesson software without a separate desktop.
• A training centre in Msheireb running a small meeting room, where staff connect laptops over HDMI and share files on the Wi-Fi connection while a team works in Arabic and English side by side.
• A government office in Doha with an air-conditioned boardroom, where the display is used for internal briefings and video calls.

Planning the installation

The unit measures 1302 mm wide, 791 mm high and 98 mm deep, and weighs 32 kg, so a wall-mount needs a structure rated for that load. It uses a 400x400 mm VESA pattern. The power supply is internal and accepts 100-240 V at 50/60 Hz, drawing 300 W nominal and 1.35 W in standby. Its operating range is 0 to 40°C with 10 to 90% humidity, which is below outdoor summer temperatures in Qatar that often exceed 45°C, so it belongs in air-conditioned rooms. Storage is rated from -20 to 60°C. The manufacturer warranty is 12 months unless local law requires otherwise.
