Skew adjustments should be made at FULL SCREEN mode and use the panel's native
resolution. In the case of a 1500VG panel (as seen above) that native resolution is
1024 x 768. Set the RGB Input Resolution value accordingly (done via the RGB Input
Resolution slider).
Do your skew adjustment using an image which contains single pixel-wide white vertical lines
(such as those seen in FIG. 113). This allows you to verify that your RGB signals are being
received at the same time.
- The lines in circle A of FIG. 113, show how all three signals are in sync and overlap to
produce the single white line.
- The lines is circle B of FIG. 113, show how the Red signal is being delivered with a
slight delay and is "throwing off" the color of the line. Altering the Red Skew value
can compensate for this delay and re-align the image.
