GREEN HORIZONTAL SIZE ADJUSTMENT
1. Adjust with RGH MSIZE so that the sizes of both ends and
of both sides of the center section of the screen are equal.
2. Adjust with GH SIZE so that the horizontal sizes of both
ends and of both sides of the center section of the screen are
equal.
3. While tracking, adjust with GH MSIZ and GH SIZE so that
the lattice intervals for the horizontal line section of the cen-
ter section of the screen are equal and so that the horizontal
size is the prescribed value.
4. If M LIN is changed when the GH MSIZ and GH SIZE ad-
justment is complete, adjust again while tracking.
• With just the H SIZE adjustment in MAIN, if there is no need
to adjust RGH SIZE in SUB this can save power.
