Clamp Tip
CLAMP TIP
moves the usual clamping pulse to prevent severe brightness or
contrast problems from certain sources. In most cases, clamping will
automatically be correct and this control has no effect on the image.
NOTE: This option does not apply to video sources or any RGB source with sync
information on the video (e.g., sync-on-green).
Use this menu to adjust the vertical size and vertical placement of an image.
Refer to Using Slidebars and Other Controls if you need help in selecting
options and accepting changes.

V-Pos
VERTICAL POSITION
moves the image up or down.
V-Size
VERTICAL SIZE
adjusts the height of the image. Values for V-size have the
following meanings:
•
1000 = 1:1 size
•
2000 = 2:1 size
•
3000 = 3:1 size
Top Blank
TOP BLANK
blanks out the top edge of an image (turns it to black). You can use
this option in combination with vertical position to center an image or portion of
an image vertically.
Active Line
ACTIVE LINES
defines how many lines from top to bottom are used to display the
image. In most cases, this number represents the vertical resolution of the current
source. For example, if the incoming image is 1280 x 1024 there are 1024 active
lines from the top of the image to bottom. When reduced, the bottom portion of
the image will be blanked.
Interlace Enable
INTERLACE ENABLE
should be “on” for all sources except HDTV sources. This
option will ensure correct image size and proportion. Set to “off” for HDTV
sources only—turning this option “off for other sources will reduce image size
by one half.
