I have a new 15" MacBook Pro running Lion. My client has a new 60" Panasonic (P60GT30) in their conference room.
They have a Windows laptop plugged in to the PC input, and it works fine.
However, when I try to connect like ...
MacBookProThunderboltPort -> Apple MiniDisplayPort-to-VGA dongle -> VGA cable -> TV's PC input
... the MacBook simply will not recognize the TV.
(Note: The TV actually has a little VGA-to-weirdPanasonicMiniConnector dongle that's needed to connect the TV; but Windows worked fine with it, why not the MacBook?)
Is there something I need to do for the MacBook to recognize and output to this TV? Maybe a new driver or something?
