they are not hdmi. The 2 on the left are firewire, one male and one female. I would think the manual should tell you something.
I have an iMac 2007 20", and there are 3 USB ports, and 4 ports I don't recognize . I am wondering if any of them can hook up to an HDMI port, as I am going to be using a projector. I don't recognize some of the shapes of the inputs. Please take a look at the picture, and tell me if it's possible to have HD picture through converters or adapters.
Thanks
