Tried connecting my 2005 Mac Mini via dvi<>vga adapter and vga (monitor) cable. TV screen says "not supported". Tried both OS10.5.8 & 10.4.11 TV is about 4 years old. Has VGA & HDMI ports. Perhaps the Apple dvi<>vga adapter does not have the correct signal or enough pins? Do not have a dvi<>hdmi adapter - perhaps that would be the answer?
