Now I did this exact same thing and it blacks out my main monitor. To get any picture at all, I have to unhook my monitor to the computer and run it in safe mode.
(for some reason, my HDTV STILL won't keep a picture once Windows is fully booted, ie it will go black after the windows logo appears)
Another question. Where would I go in AMD Control Center to do this? I'm looking and can't see any options?
Also I'm not able to even use Control Center when its in Safe mode (again, the only mode i can even see my PC in when its set up via HDMI to my TV)?
