Need help with my TV Screen..

Well, here's the problem. I got a laptop and a "HDMI" cabel between my laptop and my Samsung TV. I can see with them both, but not ingame on CA. I can see with both screens ( The TV samsung screen and the laptop screen ) on teh internet and others but NOT ingame on Ca.
So my problem is that i can't see ingame on my Samsung TV screen. Can anyone care to help me ? I've downloaded the latest drivers from ATI and still doesn't work ! Help? Tnx in advance..

You have to use Extended display options on the ATI/Windows control panel.
