I'm trying to connect my Mid 2007 imac to a panasonic LCD tv with a dvi to hdmi cable.
I've plugged them both in and the imac can see and recognise the tv and I can see all the arrangement and I can change the settings for the external screen on the imac.
But on the tv no picture appears? I've checked I definitely have the tv on the right AV input but no picture appears?
can anyone offer any help? I've read somewhere about backwards compatability and that I might need an different adaptor to the HDMI.
