If video is being input from a computer, the
image can sometimes be skewed, flickering, or
otherwise distorted.
Could the [OUTPUT FADE] button be lit?
Could "HDCP" be "ON"?
Does the output destination display support
copy protection (HDCP)?
It might be that the HDMI signal is not being
correctly transmitted or received.
Do the color space settings of the input/
output destination device and the unit match?
Are the display's settings correct?
The unit's monitor (LCD screen) is made using
precision technology, but in rare cases, it may
exhibit a missing pixel or a pixel that remains
constantly lighted.
Could you be connecting via an extension
cable or a USB hub?
—
Could you be using a USB 2.0 cable to connect
the unit and the computer?
Could the still image be a format or resolution
that the unit does not support?
Is the file name of the still image assigned
correctly?
Is the volume turned down on the unit?
Could the volume of the USB output be
lowered?
Could the sound be muted (silenced)?
Is there audio for which the solo function is
turned on?

Action
If you want to input copy-protected (HDCP) video, set "HDCP"
to "ON. "
This is a phenomenon called "tearing, " and is not a malfunction.
If the [OUTPUT FADE] button is lit, the program output video
fades-out to a black screen. To output the program video, press
the [OUTPUT FADE] button to make it go dark.
When "HDCP" is set to "ON, " video respectively is output only
from the HDMI output connectors.
If you are outputting copy-protected (HDCP) video, and a
display that does not support HDCP is connected, the video
might not be shown or might be incorrect. Connect a display
that supports HDCP.
Reconnect the HDMI cable.
Change the settings for the following menu items.
5 Video Input (HDMI) "Color Space"
5 Video Input (RGB/Component) "Color Space"
5 Video Output (HDMI) "Color Space"
Depending on the device, the color space might be linked
with the DVI/HDMI selection or the selection of format. If so,
changing the color space of the output-destination device
might solve the problem.
Depending on the display, it might overscan automatically.
Change the settings of the device.
This is not a malfunction.

computer might not recognize this unit. We recommend that
you connect this unit directly to your computer.

adjusted individually. Use the [USB AUDIO] knob to adjust the
main output volume.
