Today I replaced my ATI RADEON 9800XT with an ATI RADEON X1600Pro. I installed the correct (and latest) drivers and everything, but before my computer enters windows, I have no display, whereas previously I could see the various tests, etc. during booting.
Here comes the tricky part. On my previous card I had my projector connected to the VGA port on the card and the monitor on the DVI port, and I had a display during startup. Now with the same setup, I don't have a display during startup. HOWEVER WHEN I REMOVE MY PROJECTOR FROM THE VGA PORT AND LEAVE THE DVI ALONE ===> I HAVE DISPLAY DURING STARTUP ON MY MONITOR.
Please advise. Thanks.
