I recently had my hard drive wiped, and reinstalled win 7 pro on my optiplex 390. I have Radeon 5450 running dual monitors. When I got it back from the repair service I plugged in my dongle, and now one monitor shows yellow instead of white. When i switched the cables the opposite monitor shows yellow, so i ruled out the monitors being bad. Is it the video card or the dongle?
How do I fix the problem?
