Adjust the horizontal size by pushing the control disc to the right or to the left until the exact image width is obtained.
Adjust the vertical size by pushing the control disc up or down until the exact image height is obtained.
Note :
-If the internal # pattern was selected, this pattern remains on the screen.

4 X 3 - Use horizontal size to make image fit width of screen, then use vertical size to make image fill height (circle is round). On a wide format (1:78:1 or 1.85) screen, adjust width of image 1.33 X the height of the screen. Adjust the vertical size to fill the height.
WS - Use horizontal size to fill width of screen, then use vertical size to make circle round (use blanking to crop excess image top and bottom.) This is not necessary if you are using a 4 X 3 format screen.
ANA - Use horizontal size to fill width of screen, then use vertical size to fill height of a 16 X 9 screen (circle is nor round). Alternative: Use Anamor- phic test pattern on test disc, then adjust sizing to make anamorphic circle round. This is good to use when converging an anomorphic image onto a 4 X 3 screen.
Vertical Linearity Adjustment
The vertical linearity adjustment function corrects for vertical nonlinearities which extend from the center of the image to the top and bottom of the image.
Push the control disc up or down to highlight V LINEARITY on the Geometry menu and then press ENTER.
ENTER will select vertical linearity adjustment.
EXIT returns to random access adjustment mode menu.
ADJUST returns to operational mode.
Adjust the vertical linearity with the control disc until the distances between the horizontal lines of the set up pattern are equal from top to bottom.
EXIT will return the Geometry menu.
