Bear with me, I might not explain this very well Ive been looking at HD LCD TVs. They come with a HDMI input and a DVI. However if I plug my cpu into the DVI port the TV has a max res of eg 1300 ish. If I use the HDMI I can do 1080i, which has a res of 1920x1080 am I understanding this right? Is this the only differnce of using a DVI input?
