So, just built this amazing new computer. Have an HD4870 in it. I installed catalys 8.8 drivers, and restarted. So, expecting to have a reconized VGA, i was all hunky dorey. I here the sound fo vista starting up, i see the loading bar.but then..nothing. blackness.
I ended up having to go into safe mode, and uninstall the drivers.

1. Used the DVI to RGB Adapater and connected my display via RGB cable with my Radeon.
2. Started Vista with installed driver and no singal loss
3. Opened CCC to check "Reduce DVI frequency on high resolution displays"
4. Didnt found the option, so i unplugged RGB and plugged in DVI cable while Vista was running and i got a signal to the display via DVI.
5. NOW there is an option "Reduce DVI frequency on high resolution displays" in CCC i check it rebootet and still i get a signal via DVI but another problem accured, if i changed resolution i couldnt change it back (e.g. startet Warcraft 3 in 800x600 display res changed but as i stoped the game windows res was still 800x600 and i couldnt change it back to 1650x1050) so i went into CCC and unchecked "Reduce DVI frequency on high resolution displays" again. Rebootet and still was getting signal + res change works now. (So i cannot confirm if its its really necessary to check "Reduce DVI frequency on high resolution displays" or if the RGB/DVI cable switch while Vista was running did fix it on its own.)
