The Bay Cat X is now adjusted to the black and white levels of this computer using this video card. If you change computers or video output cards in the com- puter, you must do this again.
✎Black Level must be done before White Level. The black and white pictures must come from the real source. It doesn’t help to do this with a laptop, then plug in the “real” computer for the program.
That completes the levels adjustments. If you have more than one computer or other analog RGB source, as might come from a switcher, you should do this for each source and save the configuration to a memory slot.
Adjusting levels for computer sources manually

✎You cannot make these adjustments using the internal Test Patterns. The black/white picture must come from the computer that will be used for the program material. Adjusting levels with your laptop, then connecting to the “real” computer will not do a proper job.

3.In the Advanced Levels menu, select MANUAL BLACK LEVEL and adjust it up and down with the + \ – keys to make the three CENTER POINT values go to zero. If
they do not all touch zero at the same time, use the indi- vidual colors under MANUAL BLACK LEVEL to adjust them.
✎Do not go beyond the point where the Minimum just goes to zero. The idea is to just touch the zero level.
Next, adjust Contrast (gain) until the Image Maxi- mums just go to 255. Again, do not push it up after the
maximum is 255. Just touch the 255 point. You must adjust Brightness first, Contrast second.
If the three colors are not all at 255 (or 254), adjust them separately.
Full automatic adjustment of levels
Automatic adjustment of black and white levels does not
do as good a job as manual adjustment of levels. By select- ing Do Black/White Levels box is in the Auto Setup Options menu (Main Menu > Advanced Options > Auto Setup Options), the Bay Cat X adjusts White levels and
Black levels to the brightest and darkest pixel, respectively, in the picture. This does not work well because:
•some pictures do not contain a pure white pixel;
•some white pixels contain “spikes,” which makes them seem brighter than they really are, resulting in incorrect settings.
