Adjusting Frequency and Phase
38 m70L Installation & Configuration Guide
Adjusting Frequency Manually
1 Press
FREQ
/
PHASE
on the remote. This opens the
PICTURE
menu. Confirm that the
source is
ANALOG
.
2 Display a checkerboard pattern from the computer.
3 Select
FREQUENCY
in the menu and use the + or - keys to change the Frequency.
Don’t worry about the number that appears in the menu. Look at the screen. As the
Frequency is moved away from the ideal setting, more and more vertical bands will
appear in the picture. Adjust Frequency so there are no vertical bands.
Note: Be sure there are no zoom adjustments in effect when adjusting Frequency. If there
are, you will not be able to get rid of all the vertical bands.
Adjusting Phase Manually
1 With the checkerboard pattern still on the screen, select
PHASE
in the menu.
2 Adjust the Phase with the + or - keys on the remote. As the Phase changes, at
some points you will notice more horizontal streaking. Find a point that has no
streaking or minimal streaking. There is usually a fairly broad range of no
streaking, so settle for the point in the middle of this range.
