Hi,
I connect TV to PC via VGA, PC via DVI, Home Theater to PC via HDMI. With that combination, I can only use 1 monitor at a time.
Now I want to use my PC as main display and extend display to Sony TV, Home Theater to PC via HDMI of HD 5450 card so that I can have 7.1 surround sound.
How can I do that?
Thanks a lot!
