I'm having huge problems with my HTPC at the moment. No idea why as it was all working just fine but then suddenly went haywire. Can't get any display when switching displays to the projector - just a blank screen - and am wiondering if it has something to do with the default diisplay setting. When I choose Display properties / Settings it tells me that my primary monitor (Taxan LCD) is active but says the secondary monitor (projector via DVI) is the default display. Does anyone know how you change the default display. I am using the latest ATI Catalyst drivers (3.6) but this is driving me so nuts that I'm about to give up on the HTPC all together. So frustrating as it was all working so beatifully Any help gratefully appreciated.
