When I watch my Sony 57" KPW510 through my Component cables the color is fine on both regular and hd channels. However, in order to change the aspect ratio to watch my non hd channels in another viewing mode i.e. wide zoom I have to use a composite input. In composite mode the color is horrible (really dark). My question is, if I use dvi inputs will the color look like it does through component or composite, and will I be able to change my viewing mode with a dvi input?
