Adjusting Frequency and Phase
Adjusting Frequency Manually
1Press FREQ/PHASE on the remote. This opens the PICTURE menu. Confirm that the source is ANALOG.
2Display a checkerboard pattern from the computer.
3Select 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
1With the checkerboard pattern still on the screen, select PHASE in the menu.
2Adjust 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.
