DVI, RGB and Video Diagnostics Menu
1. The
Check Color Ramp Output
displays graduated shaded Red, Green,
Blue, and gray scale test bars. The bars should appear smoothly graduated.
2. The
Check Grid Output
is a black and white image with two diagonal
lines forming an X from one corner of the screen to the other. All grid
boxes should appear uniform, the lines perfectly vertical and horizontal, and
all the same size. Use this to correct linearity problems, using pincushion,
keystone, and trapezoid, controls.
3. The
Check Four DVI-RGB
Inputs displays all four sources in a quad grid
simultaneously.
4. The
Check S-Video Path
buttons display the same S-Video source on four
windows. All color should match on each channel (refer to the following
note).
NOTE:
If any of these inputs are composite, they are displayed in black and white.
5. The
Composite Video Four Paths
displays the same composite video
source in color, in four windows.
