Hey guys. I just build a new Windows 7 64bit system and have a Gigabyte X58 UD5 monbo and an ATI 4890 installed. I am going to run this machine with component video out, HDMI out, and potentially DVI out all at once for movie and video viewing. I installed Catalyst 9.6 and it seems like the card works fine on my DVI out. I also can set teh display to "Display 2" to see the HDMI out or teh compoenent out. I cant get Windows 7 or Catalyst to like clone display mode or use two monitors at once. It basically say I can not save these option when I try to do it in Windows. In Catalyst, I definately think something is wrong because I cant see any HDTV option nor does the Basic Wizard have any HDTV wizard. Its strange. I have tried to install and uninstall catalyst several times. Anyone know what I should do? My friend says send it back for Nvidia card.

Hi nrk7001. Errr, have you just tried connecting your HDTV or HDMI-capable display to your video card?

And your trying to display all three simultaneously correct? Perhaps the card only allows for two display outputs at once, read your manual. While I understand that your only really displaying one desktop, it might not let you mirror more than two monitors on a single card.
