I have spent my last two days trying to figure out a solution for my problem. Maybe someone has an idea whats wrong.
When the Gigabyte Ati 4550 card is in and the system boots up i have signal on both the Acer LCD/(on DVI out) and on the HDTV/(on HDMI out).
Before installing the ati drivers I had the default Win XP driver and I still had the desktop on both LCDs. It was in clone mode. After installing the ATI driver I still had the signal but then I opened the Control Center. If I press anything in there (change cloning to extended or horizontal scretch) I lose signal on the HDTV and it never comes back. If I press swap display I will have signal on the TV but not on the LCD. From that points its ONLY the TV or ONLY the LCD. I restored the system and tried reinstalling everything.. Same scenario.. Once I have the catalyst opened I have only one output.
By the way CCC recognized the LCD and the TV too.. both enabled set to their resolution.. everything seems fine... Tried the newest catalyst, and tried older ones too.
What could be the problem? Anyone ever had similar?
