I'm using a HTPC that has a Radeon X600 video card. I have installed the most
up to date drivers in it from the ATI site and I still have the same problem.
My Screen is a Dell Projector 3400mp. When windows is starting up and when it
is logging it the screen is normal. When it finishes logging it the screen
will dim down very low. My cursor will stay bright and fine but all of
windows is very dim in the back ground. The projector is hooked up through
the DVI side of the card. If I shutdown windows and hook up a monitor to the
VGA side it does fine. Windows runs fine but it is very very dim after
windows loads. Any ideas?
 
Driver issue I suspect, have you tried using the native drivers that come
with Vista?
 
Yea I have It is a fresh install of vista and it did it so I was able to make
it to ATI website to get the up to date drivers and it still does the same
thing
 
Ok new devolpment.

If I create a new user it will work fine for a few restarts and then it will
go back to the dimmed screen after login. The new user profile seems to help
it untill something is saved in it and it goes back like the other profiles.
Any ideas with this one. Thanks in Advance Josh
 
three different video cards and still same problem. Are you sure on your idea
that it is a video card. Also though it might be the system so I reinstalled
but installed x64 this time since my system can support x64 still same
problem with all three different video cards
