Cause/Check item/Solution
[1] The set time for monitoring no-signal input may be too short.
[3] Change the input signal type.
[4] If the source device has multiple output connectors, check the
video output settings of the source 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, signal may have been degraded due to the long haul
transmission. We have high-quality cables, cable boosters and
extenders. Please contact us as needed.
[6] When high-speed signal (high resolution: such as UXGA,
WUXGA, QWXGA, WQHD, WQXGA, 1080p, 4K; DEEP
COLOR signal) is 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 signal in
"9.18.9 Input signal status" and you can also limit resolution
and color depth of input signal according to the EDID setting.
You can specify the output resolution and check the color depth
of the output signal in "9.18.10 Sink device status" and you
can also limit the output signal color depth.
[7] If you set the output resolution other than "AUTO-A", check if
the selected resolution is supported by the sink device.
If you select "
1080i",
that do not support interlaced signal.
For TV output resolutions
vertical synchronous frequency. PC output resolutions (VGA to
WQXGA) may not be output to LCD TVs.
If you set "9.7.4 Automatic detection of video input interruption" to
"ON", false detection may occur. Change the setting to "OFF".
If the problem occurs in all input channels or when a test pattern is
displayed, replace the cable with a shorter one.
video may not be output to sink devices
