Cause/Check item/Solution
If the problem occurs in all input channels or at the time of displaying a
test pattern and and a long cable is connected for output, then change
the output equalizer setting.
If the problem occurs in all input channels or at the time of displaying a
test pattern, the twisted pair cable may be affected by external noise.
Check the twisted pair cable.
Change the input signal type.
Automatic detection of input signal failed. Set the input signal type
manually to "VIDEO AUTO", "VIDEO", or "Y/C".
If the problem occurs only when "CROSS HATCH" (a test pattern) is
output, the sink device enlarges and displays the video. Adjust the
sink device. If the device does not have the adjusting function, set the
the video size and position of the output.
If the problem occurs even if "CROSS HATCH" is output to all outputs,
check [8] to [13].
[8] Check the overscan setting.
[9] Settings of the display position or size are not changed?
Note: Display position and size can be set for each input or output.
[10] If aspect ratios of the input signal and output resolution do not
match, video may be cut off automatically or black may be
displayed at edge(s) depending on settings. If the video is
displayed on the full screen by setting the aspect ratio to "FULL",
there is no problem.
If the aspect ratios are not the same, you can select a) or b) below:
a) video will be cut off
b) black will be displayed at edge(s)
[11] If vertical and horizontal frequencies are displayed in "7.17.7
Input signal status", signal that is not registered in the built-in
data of the MSD was be input.
If "7.7.6 Automatic setting of input timing" is set to "AUTO
SETUP ON", input timing is measured when new signal is input.
However, if correct video is not input, the measurement may fail.
In this case, measure the input timing manually and register the
device data.
