Graphics Card Question (DVI, HDMI)

Hi, just a quick question.

My card is connected to a PC monitor (DVI) and TV (HDMI).

Is there a way to make a game load on the TV (HDMI) over the DVI, card is an ATI, cant remember the numbers but im sure its the same as they all use catalyst.

 

catalyst>desktop management>creating arranging desktop> select display>replace

 

Thanks, ill give that a go tomorrow when my HDMI cable arrives.
