Problem
Digital input video is
not output.
Analog input video is
not output.
Video is not output
Video is
disappeared,
interrupted, or has
noise.
Input video and test
pattern are not
output.
Video is interrupted.
Video is interrupted
or has noise.
[1] The set time for monitoring a no-signal input may be too short.
[2] Change the setting of input equalizer.
[3] Change the input signal type.
[4] If the source device has multiple output connectors, check the video
output settings of the device.
[5] If using a long cable for input or output, replace it with a 5 m/16.4 ft. or
shorter cable. Since the MSD has the equalizing function, long cables
can be connected, but the MSD 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 the long haul transmission. We have high-quality cables, equalizers,
and extenders. Please contact us as needed.
[6] When high-speed signals (high resolution: such as UXGA, WUXGA,
1080p; DEEP COLOR signals) are input or output, video may not be
displayed or noise may appear depending on the cable quality and the
connected device. If the problem occurs only when a specific input is
selected, the problem was caused by the input side. If it occurs for all
inputs or only when a test pattern is displayed, the problem was caused
by the output side. Change the resolution to a lower level and/or disable
Deep color.
You can check the resolution and color depth of the input signals in
"8.18.7 status" and limit resolution and color depth of input signal
according to the EDID setting.
You can also specify output resolution and check the color depth of the
output signals in "8.18.8 Display device status" and limit the output
signal color depth.
[7] If you set the output resolution other than "AUTO", check if the
selected resolution is supported by the sink device.
If you select 480i, 576i, or 1080i, video may not be output to sink devices
that do not support interlaced signals.
For TV output resolutions (480i to 1080p), check the vertical
synchronous frequency. PC output resolutions (VGA to QWXGA) may
not be output to LCD TVs.
If you set "8.5.5 Automatic detection of input video interruption" to
"ON", false detection may occur. Change the setting to "OFF".
If the problem occurs only with specific digital input, change settings of
the input equalizer.
If the problem occurs with all input channels or when a test pattern is
displayed and if a long cable is connected for output, change the output
equalizer setting.
