My computer monitor has a green cast to it and we tried another monitor and it was still green. Is there a setting somewhere that could have gotten change. We were exchanging monitors with another computer and when we hooked it up it had a green cast to it. We exchanged them back like they were but the green cast is still there.
I didn't know this until later, but my husband said when he made the switch that he didn't shut the computer down. Would that have anything to do with it?
