Problem
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.
The left, right, top
and bottom sides are
cut off.
Cause/Check item/Solution
[1] The set time for monitoring a no-signal input may be too short.
[2] Change the setting of input equalizer.
[3] If the source device has multiple output connectors, check the
video output settings of the device.
[4] 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.
[5] 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
"7.16.7 Input signal status [INPUT 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 "7.16.8 Display device status [MONITOR
STATUS]" and limit the output signal color depth.
[6] 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 "7.5.4 Automatic detection of input video interruption
[INPUT OFF CHECK]" to "ON", false detection may occur. Change
the setting to "OFF".
If the problem occurs only with specific 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.
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
video size and position of the output.
If the problem occurs even if "CROSS HATCH" is output to all outputs,
check [7] to [11].
