Can not get both picture and sound

[banhien]

Hi all,

I'm having problem with my HDMI from a Studio XPS 13 to a Panasonic TV. Both NVIDIA control & Vista 64bit know the external TV and setup right resolution (1920 x 1080) BUT noway I can have BOTH sound and video/picture at the same time. I can only get sound or picture or nothing after playing around with Nvidia control and Personalize in Vista

Here are few photos which show the setup:

Help.

Finally I have to make the TV as primary monitor and it works. No idea why I have to setup like that.
