Video output
Video is not output.
[4] If a long cable is connected for input or output when digital I/O slot
board is mounted, replace it with a 5 m/16.4 ft. or shorter
Cable. Even though a 5 m/16.4 ft. or longer cable can be
connected for digital I/O of the FDX, HDCP authentication or
EDID acquisition may fail depending on the cable quality and the
connected device.

[5] Are signals that are not supported being input?
[6] Change the time for ignoring video output request signals.
[7] Is the set monitoring time for no signal input too short?
[8] Check the video output setting of the source device.

If a long cable is connected for input or output when a digital I/O slot
board is mounted, set the input or output equalizer.
If a long cable is connected for input or output when digital I/O slot
board is mounted, replace it with a 5 m/16.4 ft. or shorter
Cable. Even though a 5 m/16.4 ft. or longer cable can be connected
for digital I/O of the FDX, the FDX may not provide its full performance
depending on the cable quality and the connected device. If the
problem is solved by replacing the cable, signals might have been
degraded due to long haul transmission. We have high-quality cables,
cable boosters and extenders. Please contact us as needed.

When high-speed signals (e.g.: high-resolution signals such as UXGA,
WUXGA, and 1080p, and Deep Color signals) are input or output,
video may not be displayed or noise may appear depending on the
cable quality and connected devices.
If this problem occurs in all output connectors, check the input side. If it
occurs in a specific output connector(s), check the output side as
follows: Change the resolution lower and/or turn off DEEP COLOR.
You can check the resolution and color depth of input signals in the
LCD screen, and you can set the EDID in order to control the
resolution and color depth of the input signals.
Is a cable that is appropriated for the transmission distance when a
twisted pair I/O slot board is mounted?
If the transmission distance is 50 m/164 ft. or longer, we recommend
using a Cat6 cable whose noise characteristic and frequency
characteristic and using STP cable instead of UTP cable to reduce the
influence of interference and external noise.
If the transmission distance is 50 m/164 ft. or shorter, you can use a
Cat5e cable.
When an HDBaseT I/O slot board is mounted, connect cables
correctly (place them straight) to reduce the influence of noise. Keep
the distance among cables and not to place cables closely in parallel.
