3.2.3Adjusting Levels for Analog Computer Sources

This section applies to Analog RGB (computer) pictures only. The Levels are best adjusted semi-automatically.

Why adjust levels?

For analog RGB pictures the levels for black and white vary from one computer to another, or from one video pro- cessor to another. They even vary between video outputs from a multiple-output video card in a computer.

Your pictures will not look their best on Bay Cat X until you adjust for these differences. This is not about adjusting color or contrast. It’s about telling the Bay Cat X what the computer or processor means by black and by white.

Semi-automatic adjustment

1.From the computer source, display an all-black picture. This must come from the computer source that will be used for the program. It does no good to use your lap- top for this adjustment, then connect to a different com- puter for the program. Nor can you use the Bay Cat X’s black test pattern. (Hint: Display a black screen using Windows Paint program.)

✎To adjust levels for UXGA sources that will be displayed in One to One scale mode, perform your adjustments using Fill All scale mode and then switch back to One to One.
