PIP/PBP Compatibility
Not any two inputs can be simultaneously displayed in PIP or PBP modes. For
example you cannot have two VGA inputs simultaneously displayed. This is
due to A/D converters that are shared between them. The following table
indicates which signals are compatible for PIP/PBP windowing. Pick the
background image along the left column, and then the checkmarks tell you
which other inputs can be windowed with it.

5. Troubleshooting
Problem Solution or Possible Cause
Screen is blank Verify the screen output is not set to blank.
Verify your source is emitting a proper signal.
Verify cable connections.
Try other output resolutions
Remember due to HDCP compliance VGA output
will be blanked for HDMI inputs
Outside edges of the image
are cut off (image cropping)
particularly when a PC input
is shown on HDMI display at
HDTV resolution.
Static or other video
interference
Some displays intentionally crop HDTV inputs
(720p or 1080p resolutions particularly) slightly.
The amount of cropping varies by each display.
Therefore, the only way to correct this is to scale
the image down to the viewable area. You can do
this in the OSD menu under “Position” settings
by adjusting H
If you still get a bad image or no image at all, it
means that your display does not support PC
resolutions on its HDMI input. In that case look
for a DVI input on your display. By definition they
ought to support the gamut of PC resolutions on
their DVI input.
If you still can’t get a proper image, please
understand that this is an anomaly of your
display and you may need to try a different
display that can handle PC input resolutions
properly without cropping.
Make sure unit is properly grounded. Use the
grounding connector on the rear panel of the
15
9x2 Presentation Scaler Switch
chassis.
Front panel buttons not

Serial control not working Verify the correct com port settings. Refer to the
Video colors not correct Check the color settings of the device. Reset back
