Blank Console after VUE logoff on D220s

Thanks everyone for the suggestions.

I have two D220s with this problem. They both use the same type monitor, A4330A. They were both OS loaded with these monitors and identical HP graphics cards.
The blank screen occurs when logging off of the VUE session using . The screen goes blank, no cursor, mouse, zip. The monitors appear to still be in sync because the LED stays Green.
I am still working on the potential solutions provided, but if any of this helps to narrow the possibilities please let me know.

Thanks,
Mark
