4 Units
4 X 3 Type 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 Anamorphic 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.

which extend from the center of the image to the top and bottom of the
image.

etry menu and then press ENTER.
