Hi my Sony Viao will not display on my Samsung LE40M87BD TV.
It is not a straight forward problem. The TV will recognize my Mac mini on a VGA lead and then if I unplug the VGA lead and plug it in to my laptop the desktop extension will appear on the TV. Fine but if I change the source on the TV and come back to the PC port it is blank on the TV, well on the Samsung if it dose not see a input it dose not give you the option to display this input. I have checked my Sony and updated it as much as I can but it is not sending a signal to the TV to say here I am. My Nvida graphics card can see the TV but I am stuck any ideas would be grateful.
