All, I too have a Sony Bravia and a Macbook Pro with a mini display port. I bought the Apple attachment to connect my mini display port to a HD15 cable with ferrite core. I plugged the HD15 cable into the rear of my TV where it says RGB. Everything fits well, but I am still seeing only two external inputs for the TV: my DVD player and my cable box. The TV doesn't seem to know that I have a computer attached to it. The user manual for the TV says I should change the output signal from the PC to a certain resolution. Tried that. I really don't know what I am doing. I want to display a Powerpoint presentation and a set of photos from Iphoto on the TV this Sunday (January 29, 2012). Will I be able to do that when I get this working? I thought I could use the TV like an external computer monitor. I need some step by step instructions including what order to turn the TV and the computer on, and when to connect the cable to the mini display port. I have read that I should use PF7 on my Macbook, but I don't think that may be from a different version of Macbook than mine. Mine doesn't seem to have the "mirror display" icon on any of the function keys... Can anyone help?
