Quick Start Guide Prestigio Digital Signage Video Wall
Pixel limitations
The LED video wall system supports a dot matrix resolution of up to 1920X1080 pixels.
However, the signal distribution system LDU only supports up to 1024X768 pixels. That is
to say, an LED video wall larger than 1024X768 pixels would need a special LDU connection
arrangement.
Limitation of signal connection
Due to the pixel limitation of the LDU, an LED video wall larger than 1024X768 pixels would
need more than one LDU to support distribution of signals. When multiple LDUs are
connected together, the right starting point of each LDU on a picture must be appointed
and preset.
Example: Signal connection of a LED video wall with 1280X768 pixel
Limitation of power connection
As a rule, each column of cabinets of an LED video wall is connected by an AC power
cable to the PSU for power supply. However, if the LED video wall is extremely large and
comprises of more cabinets than could be supplied by one power cable due to current
restriction, it becomes necessary to use multiple power supply cables which need to be
connected to different power output terminals at the PSU.
Example: Power supply connection of a LED video wall with 960X600 pixel
