  You nailed it, he went into the  TV's config's for HDMI input and set that to 
PC based input and it worked.  ATM he is not running ATI's driver, but is 
going to look and test it out for his "card".  (If he had asked me before 
buying the hardware, I would have told him to go for the nVidia based chipset.
