Tom, Thanks for the suggestion. I don't think they are the same issue as the video chipsets are different and they at least saw the graphics for a time. The one I have is newer, not part of the 4500 series and I never have graphic output. I tried the parameters you sent and it did not have an effect. I still get the blank screen at mode switch time.
