Display Commands Descriptions
Command Arguments Description
OVerScan <input #> [ON | OFF] Performs an automatic 2% enlargement on video
inputs only. It has no effect on WSR values, and it
applies to all video inputs for the specified channel.
Overscan is useful in trimming out excess blanking
in video signals, or “head switching” for VTR
sources. Unlike WSR, when Overscan is turned on,
the enlargement is automatic and constant even when
switching between the various video input types.
Default: OFF
PAN <input #> [<i | j | m | l>
<repetition>]
Activates the pan function for the selected input.
Only a zoomed input can be panned. Controls are
listed below:
i = pan up j = pan left
m = pan down l = pan right
q = quit
POSition <output #>
[<direction>
<repetition>]
Activates the position utility, allowing you to move
the specified input window around the specified
output. Controls are listed below:
i = move up
m = move down
j = move left
l = move right
q = quit
The direction and repetition arguments
allow you to repeat a movement in one direction
without repeatedly pressing the key. For example, to
move output 1 to the left 20 times, type:
POS 1 j 20
The actual pixel or line increments that a window
moves is determined by the Setrate command. In
the above example, the window moves 400 pixels to
the left (20 times the default rate of 20 pixels).
Position affects the WDR value for the input.
ResetSourceRectangle <input #> Resets the source rectangle (WSR) to default value that
is equal to the HACT and VACT measurements of the
specified input signal. Note RSR “unzooms” a
zoomed image.
SETRATE <x-rate> <y-rate> Determines the number of pixels (x-rate) or lines (y-
rate) an output rectangle moves with the
POSition
command.
Default: x = 20, y = 20
