Trouble cloning display

[Maplicito]

I'm here to abuse the board's knowledge base again. This time, I'm having trouble getting my Catalyst Control Center to allow me to set up a second display (tv) and clone the first display to it.

I had this working previously - I've installed a couple of games since then, and I've upgraded from a Q8200 to a Q9550. I COULD uninstall the games if need be, but my preference would be to not if it's not necessary.

ATI CCC will detect the TV, or I can force detection - either method shows the display as being available - but I can not drag it to "Display 2." If I right click on "Display 2" instead of on the tv in the disabled displays list, it has the option "Enable Display" but when I choose this - it appears enabled (according to my computer monitor, not the tv - the tv is in an entirely different room, so I can't see it to verity) for a brief second, then goes back to disabled.

I uninstalled CCC and my driver, and reinstalled them. No luck. I suspect I'm missing something simple - any ideas? Oh, it's an HD 4670 1GB, and I'm running Vista 64 Ultimate. Thanks in advance as always.

I cleared this one up on my own. My PC has an S-video out and two HDMI connectors (hooked up to my old monitor via a VGA adaptor). After upgrading to my Q9550, I must have inadvertantly hooked my monitor up to the secondary HDMI instead of the prmary - switching HDMI ports has brought back my ability to clone onto the TV.
