Cause 4:
The DVI / HDMI lead is kinked or damaged.
Remedy:
The cables must be in perfect condition, i.e.
they must not exhibit damage or sharp
bends (kinks) (radius less than 10 cm).
Please check the leads and either re-
deploy them or install replacement cables.
Cause 5:
The HDMI / DVI connecting lead is
excessively long.
Remedy:
The extremely high-frequency DVI / HDMI
signals can be transferred over distances of
up to about 10 ... 15 m if top-quality cables
are used. For longer distances, special
optical glass fibre cables can be employed;
these
connectors at the input and output ends.
If you wish to use these cables (known as
active cables) with your VSP 1250 R,
please note that they must be powered by
their own mains PSU. They must not draw
their energy from the HDMI output of the
VSP 1250 R, as this could cause damage
to the machine.
