Top blanking

Set a top blanking value Example

Increment top blanking value Decrement top blanking value View the top blanking value

X@*X1$(	X@BltX1$]
1*2(	1Blt2]
X@+(	X@BltX1$]
X@–(	X@BltX1$]
X@(	X@BltX1$]

Blank the top two lines of output 1. Increase blanking value 1 line. Decrease blanking value 1 line.

Bottom blanking

Set a bottom blanking value Example:

Increment bottom blanking value Decrement bottom blanking value View the bottom blanking value

X@*X1$)	X@BlbX1$]
2*5)	2Blb5]
X@+)	X@BlbX1$]
X@–)	X@BlbX1$]
X@)	X@BlbX1$]

Blank the bottom five lines of output 2. Increase blanking value 1 line. Decrease blanking value 1 line.

Pixel phase

Set a specific pixel sampling phase Increment sampling value Decrement sampling value

View the sampling value

X@*X1%U

X@+U

X@–U

X@U

X@PhsX1%]

X1%]

Specify the pixel sampling phase. Increase the phase value. Decrease the phase value. Show the pixel sampling phase.

Horizontal detail filter (RGB and component video inputs)

NOTES:

•The horizontal detail filter is available only for RGB and component video inputs. The same command with a different X` variable is available to set a combined detail filter for S-video and composite video inputs.

•The X@ value specified is the output to which the filtered input is switched.

•The command (D) is case sensitive.

Set a specific filter value Increment filter value Decrement filter value

View the horizontal filter value

X@*X1^D	X@DhzX1^]
X@+D	X@DhzX1^]
X@–D	X@DhzX1^]
X@D	X1^]

Set the horizontal detail level. Increase the horizontal detail level. Decrease the horizontal detail level. Show the horizontal detail level.

Vertical detail filter (RGB and component video inputs)

NOTES:

•The vertical detail filter is available only for RGB and component video inputs.

•The X@ value specified is the output to which the filtered input is switched.

•The command (d) is case sensitive.

Set a specific filter value Increment filter value Decrement filter value View the vertical filter value

X@*X1&d	X@DvzX1&]
X@+d	X@DvzX1&]
X@–d	X@DvzX1&]
X@d	X1&]

Set the vertical detail level. Increase the vertical detail level. Decrease the vertical detail level. Show the vertical detail level.

NOTE: X@ = Output number		1 or 2
X1$ = Blanking value		000 thru 200
X1%	= Pixel sampling phase	000 thru 031
X1^ = Horizontal filter value		0 thru 3
X1& = Vertical filter		1 thru 7
