just bought a samsung hd tv (http://reviews.us.samsung.com/7463/LN37B550K1FXZA/samsung-ln37b550-37-1080p-lcd-hdtv-2009-model-reviews/reviews.htm) . and wondering if i can watch videos from pc to hd tv via dvi -hdmi. my computer has a dvi output and the new hd tv has hdmi inputs. So do i just buy a dvi to hdmi plugin cable? or do i need to buy a dvi to hdmi converter and plug that into the computer and then get a separate hdmi cable and attach it to the other end the the converter and into the hd tv hdmi port? how audio? will there be audio? my new hd tv has a built in internal speakers. what can i do about audios if dvi-hdmi method doesnt provide it?
