This is a re-post of the original that I posted here that no one has replied to.

I am having difficulty setting up HMDI out with my Toshiba A200 laptop. I have the drivers that are installed when you go to System > Administration > Hardware Drivers and click "activate" on the "ATI/AMD proprietary FGLRX graphics driver" and I also have Catalyst Control Center.

Basically I plug in my HDMI cable and the laptop screen flickers to black for about 2secs then returns to normal, and my TV screen displays static colourful bars of noise. The TV screen does not show up as a screen under CCC settings OR "Desktop Resolution" under Preferences.

I have read here that it *should* work out of the box.. but isn't for me.
How do I go about setting this up?
