whats the diff between them? i also have an apple monitor but it has a adc cable so im getting a adc to dvi adapter as show in this link http://www.newegg.com/Product/Product.asp?...N82E16812116204 but my video card says it supports vga, dvi-i, and s-video out. so i just wanna make sure the dvi matches my dvi-i output..
