HDMI - iMac to a sony LCD tv
Can't locate a HDMI socket behind my imac, how do I connect an HDMI cable to my imac from my sony TV?
There is no HDMI connector on iMac computers. Only the Mac Mini has an HDMI port.
If your iMac is of recent vintage (generally 2009->present) then it has a miniDisplayPort video out connector or a Thunderbolt port, which is 100% compatible with miniDisplayport port and uses the same connector. To connect to a Sony HDTV that has an HDMI input you need one of the following:
Apple miniDisplayPort to DVI adapter plus a DVI-to-HDMI cable
or
Combined miniDisplayPort-to-HDMI cable
Here is more information about Apple miniDisplayPort adapters and miniDisplayPort to HDMI adapters
Note that in general while the miniDIsplayPort can output both video & audio, if you use a DVI cable it will probably only carry the video, in which case you will also need to connect your iMac's audio out to the Sony TV audio in.
