No, I have tried to change the input selection (of course, as I said, it workes with my old computer) and I have the windows 7 computer now connected to an ordinary monitor with DVI connection now and it works. It just wont connect to the TV. Is there any settings how to put settings so windows 7 l allows multiple monitors?
