To Display the Supplied Skew Test Pattern
1. Insert the supplied Avocent CD-ROM into the CD player
of the computer.
2. Within Windows, use the My Computer option (usually
available as a desktop icon or within the Start menu) to
view the contents of the CD-ROM. Double-click the Skew
entry to display the standard test pattern. If necessary,
maximize the application window so that the image lls
the screen.
The screen will show a series of ne red, green and
blue crosses which should all be in line, vertically and
horizontally- skew affects the horizontal placement of the
colors.
To Zero the Skew Adjustment Dials
When supplied, the two skew dials are set in their neutral positions.
i.e. no delay to either of its colors. However, if the unit has been
previously used and adjusted then you may need to relocate the zero
point. There are no setting markers around the two skew dials and the
dial itself does not have a pointer.
1. Insert a small screwdriver into the skew dial and twist it all the
way counterclockwise. Note the position of the dial when it
reaches its end point.
2. Rotate the screwdriver fully clockwise and again note the
endpoint position of the dial.
3. Now rotate the screw driver counterclockwise until the dial
reaches the position that lies midway between the two end points.
This is the neutral position.
4. Repeat this procedure for the other skew dial, if necessary.
