Video output (Cont’d)
Video is intermittent,
or presents noise.
If using a long cable for input or output, replace it with a 16.4 ft.
(5 m) or shorter cable. Since the HDC has automatic cable length
equalization, long cables can be successfully used, but the HDC’s
full performance may not be realized if the cable or connected
peripheral devices are of inferior quality. If the error is solved by
replacing the cable, the signal may have been degraded due to
excessive attenuation or crosstalk. IDK offers high-quality cables,
cable boosters and extenders. Please contact us as needed.

5 System Configuration Example
The transmission clock of Deep Color signal is faster than that of
normal signal. If lo-quality or long cable is used, noise may
appear.
You can control Deep Color of input signal by setting EDID.
