4.  Operation
Using the Setup Menu
Select V Size to size both the top and bottom edges simultaneously.  Values are 
in lines.  The output “window” is maintained in both size and aspect ratio.  
Select H Pan to pan a “sized” image left and right — within the selected aspect 
ratio.  Values are in pixels.  The value reads [0] if the image has not been sized 
horizontally.  
Select V Pan to pan a “sized” image up and down — within the selected aspect 
ratio.  Values are in lines.  The value reads [0] if the image has not been sized 
vertically.    
The Aspect Ratio function allows you to set a pre-defined or custom ratio for the input.
Select Aspect Ratio to adjust the image to one of the following values:  1:13:2
4:35:416:9Custom.
If Custom is selected, the Ratio line appears: 
~
Adjustment range
:  0.750 to 3.000.  The default value depends on the 
last Aspect Ratio selected before Custom was chosen.  
~
Note that the DCS-200 displays the input video aspect ratio according to 
the input format detected.  For example:
S
Computer video at 1280x1024@60Hz defaults to 5:4 aspect ratio
S
NTSC video defaults to 4:3, HDTV 1080i video defaults to 16:9
`çåíê~ëí
From the Input Menu, select Contrast to change the contrast of the selected input. 
Adjustment range
:  75.0% to 125.0%
Default
:  100%
_êáÖÜíåÉëë
From the Input Menu, select Brightness to change the brightness of the selected input. 
Adjustment range
:  75.0% to 125.0%
Default
:  100%
Note
For both H Size and V Size, the function always cuts into the 
visible image, equally on both sides, and never exposes 
video outside the source’s active area.  As you size, the 
DCS-200 scales the input up to fit the selected aspect ratio.
Note
The maximum allowable H/V size is up to 33% of the input's 
corresponding active area. For example, for a 1280x1024 
input,  the maximum H Size is 422 and the maximum V Size 
is 336. 
Note
If both H Size and H Pan are greater than 0, and H Size is 
adjusted so that it approaches 0, at a calculated limit, H Pan 
automatically adjusts itself to approach 0.  This same rule 
holds true for V Size and V Pan.
