10 Troubleshooting
In case the DDC-03UHD does not work correctly, please check the following items first. Also refer to manuals
for connected devices as well, since they may possibly be the cause of the problem.
･Are the DDC-03UHD and all connected devices powered on correctly?
･Are cables connected correctly?
･Are there no short circuits, disconnections, or loose connections?
･Are appropriate cables for the DDC-03UHD being used?
･Are signal specifications of connected devices matched to each other?
･Are settings of the sink device correct?
･Are there any nearby objects that may cause noise?
If the problem still cannot be solved, please check needed items.
Problem
● Video output
Video is not output
Cause/Check item/Solution
[1] Does the DDC POWER LED illuminate? If not, ensure that a
monitor is connected to the DDC-03UHD and powered on.
[2] Check the HDCP of the digital input video.
Some source devices check whether the sink device is HDCP
compliant or not and they output video depending on the result.
Because the DDC-03UHD supports HDCP, video cannot be
displayed if a non-HDCP compliant monitor is connected. In
such a case, disable HDCP input in "8.4 HDCP input Enabled /
Disabled".
[3] The set time for monitoring no-signal input may be too short.
Change the setting to longer time.
If you set shorter time than the time which the source device
outputs video, the source device may not output video. In such
a case, change the setting to longer time.
[4] Is the selected Built-in EDID supported by the monitor?
・If Built-in EDID is set to "1920 x 1080i", video may not be
output to monitors that do not support interlace signal.
・While some monitors for PC does not support HDTV
resolutions, some LC TVs and plasma TVs do not support
VESA resolutions (XGA to WSXGA+).
[5]
Is a resolution that is not supported by the connected monitor
input?
Check the resolution and video frequency and refer to the
monitor's specification.
[6]
If the source device has multiple output connectors, check the
video output settings of the source device.
