When changing the width of the window, the height will automatically adjust to
match the aspect ratio. When
Lock Aspect Ratio
is set to
On
, the aspect ratio of
the video display will be maintained, even if the window is stretched. If the
image is
4:3
and it is stretched to
16:9
, the results are two vertical black bars
appearing on either side of the display. If the image is
16:9
and it is scaled down
to
4:3
, then it will have a letterbox effect.
Frame Memory Status
This allows the image from DVI cascade input not to pass through the image
scaling processor DDR for processing. Rather, it will bypass to the display
output port. This will lessen the occurrence of frame delay when multiple
Rainier is cascaded. No special setting is required as the firmware can
automatically detect and perform the frame memory bypass function.
IMPORTANT: Make sure when making the hardware connections that the module ID must
be set at 0 and the DVI-I Input must be used to connect other than the Rainier’s DVI
Output signal. This means that the sequence of connection must be as follows: PC DVI
Output
Æ
ID 0 DVI-I Input , ID 0 DVI-I Output
Æ
ID 1 DVI-I Input , ID 1 DVI-I Output
Æ
ID 2
DVI-I Input , ID 2 DVI-I Output
Æ
ID 3 DVI-I Input , ID 3 DVI-I Output
Æ
