Is there a setting that can be changed that keeps the screen from going black when changing between?

I presume you mean switching between a virtual console and an X session, or between multiple X sessions. AFAIK, it can't be prevented because the video output to the display changes and the monitor takes a brief time to re-sync.

When I have run multiple X sessions, even when the resoultion is the same, the black screen stills appears for a second or two.
