Video is not output.
・
If no error code is displayed:
Set “
”
to a pattern other than “OFF”. If any
test pattern is not output, check [4] to [6]. If a test pattern is output, the
source device may not output video.
－
Input video is not
output.
[1] The set time for monitoring a no-signal input may be too short.
[2] Change the settings of input equalizer (only for HDMI connector.)
[3] If the source device has multiple output connectors, check the video
output settings of the device.
－
Video is disappeared,
interrupted, or has
noise.
[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, signal might have been
degraded due to the long haul transmission. We have high-quality
cables, cable boosters and extenders. Please contact us as needed.
In case of HDBaseT input, twisted pair cable might be having external
noise. Please check twisted pair cable.
[5] When high-speed signal (high resolution: such as UXGA, WUXGA,
1080p; DEEP COLOR signal) 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 signal in “
8.15.1 Input signal status (P.105)
” and
can 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 signal in “
8.15.2 Sink device status (P.108)
”
and limit the output signal color depth.
Input video and test
pattern are not output.
[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 signal.
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.
。
Video is interrupted.
If you set automatic detection of input video interruption
to “ON”, false
detection may occur. Change the setting to “OFF”.
Video is interrupted or
has noise
If the problem occurs only with specific digital input, change settings of the
input equalizer.
