Ive just bought the top end ATI Radeon card with 2 normal monitor ports and a HDMI.

The idea was to continue using my dual screen setup as always and to use the last plug, the HDMI on my TV. I got a new 52 inch HD TV with all the necessary bits. This should work fine.

But.. in Display Properties I still get only my 2 monitors up as options. Not the Digital TV.

When I unplug 1 monitor and restart the computer, I get the TV and the other monitor. But never all 3 at the same time. Why is this ? Where can I go to tell it that I need all 3 screens at the same time.

Also I get a message saying my gfx card also gives sound through the HDMI cable.. But the TV tells me its recieving a sound format that it does not understand. Any ideas on that too while were at it ?
