3200MP green color problem

When my 3200MP projector is warming up I get a wonderful bright white light. However, when the signal is found by my computer the light changes to green. Everything is green tinted--my presentation, the desktop, the light emitted by the projector. I have tried connecting the projector to a different PC with the same results. I've tried altering the default color settings, brightness and contrast levels. Then, I reset everything back to factory defaults since the problem was not resolved.  What can I do next?
