I understand that I can connect my pc to my tv using the vma, dvi, or sd ports through my graphics card. Can I connect my pc to my tv using the hdmi port in my monitor to my tv and see pictures and sound. I have a Gateway 22" monitor that has vma, dvi, and hdmi hookup. My graphics card only has vma, dvi, and sd. Whay exactly is the hdmi in the monitor for. Also, if I use the sd cable how do I get sound to the tv?
