I am looking to plug a CRT (SONY FW900) into an apple G5. I am assuming that the G5 has only dvi inputs in the back. I know I am going to need a small connection to convert the signal. Now, I know everything is digital these days, and that those DVI ports in the back were made for a digital display. Can someone explain to me what happends during the conversion from DVI to VGA? I am studying to be a graphic designer, and would like to know how much information is lost during the conversion.
