I own a 50" samsung plasma tv model numberPN50C450 and was hoping i could hook this up to my computer desktop as a monitor? And using what input/output combo? Would my graphics card have to support anything unordinary? I have a 7850 radeon. Im convinced on buying a hdmi to dvi cord to make this happen seeing my tv is digital and this is a digital connection? But IM uneasy with this because idk if the audio will transfer also, and i dont want to be stuck with video but no audio. Can someone help?
