Input Level

When the black and white levels are correctly set, the display will know what the absolute minimum and maximum signal amplitude is that the source is sending to it. The procedure for Input Level adjustment, and the menus for it, are different for computer sources and video sources.

You must adjust input level for each source that is connected to the display. Even if two similar sources are being used, such as two different SVGA sources, the input levels must be adjusted for the source that is connected at this time. When the other SVGA source is connected, the levels must be readjusted to match the new source. If the sources are connected to different inputs (SVGA, MAC, RGBS) then each source’s Level can be set and saved separately in memory, because there is a different memory for each source-mode combination.

For all sources except composite and S-video, the input Black Level must be adjusted to match the source before adjusting the input White Level.

Note: Do not use Black Level Adjust and White Level Adjust to color balance the displays. Matching the displays so they all produce the same colors is done in a later step called Color Balance. Color Balance and Level Adjust are entirely independent of each other. Level Adjust must be done with external video signals. Color Balance should be done with internally generated patterns.
