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 fills 
the screen. 
 
The screen will show a series of fine 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.
