Note : No horizontal phase adjustment is available on the internal # pattern.

For external sources :

If the raster shift is correctly adjusted, the H Phase text box is projected in the middle of the raster. At that moment, the "><" icon indicates the middle of the raster.

Adjust the H Phase control until the middle of the projected image is equal with the middle of >< icon.
