I have a 50' DLP Samsung and it had a VGA input on the back for your PC as well as HDMI and component Inputs. I am getting a Satellite receiver with a DVI output. I am wondering if the picture would still be HD if I used a DVI to VGA cord. Or would It be better just to use Component cords? I heard component isnt actually HD. I want to keep the HDMI input free for later use.
