I am wanting to play my ps3 on my iMac, essentially plug the HDMI into something and have it display on the iMac. I have a pre-thunderbolt unit, late 2009 (will add sceenshot below). I do know that there is a display port, though I am not sure if that is limit to output only or if I can do an input on it. Sound is not crucial, but would be nice. I have been doing some searching but I am finding widely varying responses. Hopefully I can get a definite yes or no. If yes, maybe a link to the product I would need.
