Thanks for the direction.  I researched both and this lead me to other utilities.  It looks like UltraMon might do the trick.  
http://www.realtimesoft.com/ultramon/My problem is that I always want to get GameEX to always open on the secondary monitor which is the Component Out.  Then the GameEX front end is closed, the screen reverts back to the S-Video.    The built in ATI Hydravision software would not to it, nor would the default windows extended desktop features.  
Thanks Agin for the help.  
Next I am going to try to figure out how to trigger some output on my PC to power a relay switch to automatically switch my TV from Component to S-Video input, when I switch between desktops.
