I have a vga board for my PW6, I have my Mac Mini connected through the built in vga input and my Sky+ going through the terminal board vga. Sky used to go through the built in one until the Mac arrived and now I am wondering if the quality for Sky is as good now I have changed it over to the second vga. The quality should be the same shouldn't it? I am expecting its just in my head but I am sure the picture looks slightly muddyer than I remember?! Also, I am now using a different vga cable (not as good I don't think) so I'm guesing that isn't helping. But cable aside are the vga terminal boards going to give the exact same quality as the built in one?
