. .

Images have the wrong
aspect ratio (e.g., are
stretched) or are not
positioned correctly

•

Try selecting a different output from the “

Factory

Timing List

” to better match your display.

•

Determine that there is not a mismatch between your
output and the selected monitor display (e.g., 4:3 output
and 16:9 display monitor).

•

Use the “

WindowSourceRectangle

” (WSR) and

“

WindowDestinationRectangle

” (WDR) functions to

check or modify the image’s aspect ratio.

Blank image (the output is
black)

•

Ensure that the source is properly connected to the system,
powered on and generating a signal.

•

Ensure that the correct input type is selected using the
“

INputSouRCe

” command.

Frozen image

If an image is frozen after system start-up, turn freeze off using the
“

FReeZe

” command.

Missing imagery

•

Check the “

WindowSourceRectangle

” (WSR) value

to ensure the entire image is being processed.

•

Check WSR and “

WindowDestinationRectangle

”

(WDR) to ensure that the source and destination
rectangles are delivering the entire video image.

Poor quality video

•

Check the video source for proper operation.

•

Check that cables are in good condition and connected
correctly.

•

Ensure that video sources are not double terminated.
Double termination can occur when one video source is
split into two using a “T” connector instead of a
distribution amplifier.

•

If you are using a VCR, check the quality of the tape.

•

Adjust the brightness using the “

BRIghtness

” command.

•

Adjust contrast using the “

CONTrast

” command.

•

Adjust saturation as required using the “

SATuration

”

command.

•

Adjust the hue as required using the “

HUE

” command.

No color on the S-Video
input

•

Check that the “

SATuration

” setting is set to normal.

Adjust as necessary.

•

Check that the S-video cable is connected correctly.

•

Check that S-Video has been selected as the source using
the “

INputSouRCe

” command. If you select

Composite2 when you have an S-Video signal connected
to this port, the input will be displayed as a black and
white (luminance only) signal.

Aspect Ratio on a video
input is incorrect.

Check the status of the “

VideoAspectRatio

” command. For a 4:3

aspect ratio signal, this should be set to normal.

Table D-1.
