How can I achieve to get 1x1 mapping from pc to a RCA D40W135D (HDTV) ? I'm using a sony viao laptop that does not have a great video card. I understand that there's a software that can custumise the res output from computer to tv. I don't know the name of it. I want to achieve this by connecting to the tv via vga (pc) --> dvi (tv) through an adaptor and dvi cable.
