How come I no longer get a new display detected dialog box when I plug in my tv into my lap top?

I am trying to play a pc game on my TV, but it is stuck on the laptop screen.

I tried UltraMon and set a hotkey to move the window to the other monitor, but the game refuses to stay there, (blinks on the TV for a second the reverts to the laptop screen.) The Mirror mode in Ultramon is to laggy for gaming.

I've tried Using the Windows Mobility Center, But like I said, The dialog box I need does not appear. Catalys control center refuses to run. This is a fresh install of Vista, Catalyst, and the game. Please I am tired of using this little screen for games!
