Someone had set up the Sony Bravia for me when I bought it, and they renamed the inputs. I figured out (finally) how to set the TV to the VGA input (called PC Input on the Sony Bravia). Later when I had everything working, I went back and played with the resolution of the screen.

I went to system preferences/display/arrangement and picked Mirror Display. On the Macbook Pro, I went to system preferences/display/detect displays and it downloaded a Sony TV display for me. With the VGA hookup, it did recognize the TV (it went blue screen temporarily on the Macbook Pro). I tried HDMI hookup but my macbook pro didn't recognize the TV. Mine doesn't seem to have the "mirror display" icon on any of the function keys. 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. 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. 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 want to display a Powerpoint presentation and a set of photos from Iphoto on the TV this Sunday (January 29, 2012). The user manual for the TV says I should change the output signal from the PC to a certain resolution. The TV doesn't seem to know that I have a computer attached to it. Everything fits well, but I am still seeing only two external inputs for the TV: my DVD player and my cable box. I plugged the HD15 cable into the rear of my TV where it says RGB. I bought the Apple attachment to connect my mini display port to a HD15 cable with ferrite core. I too have a Sony Bravia and a Macbook Pro with a mini display port.

If anyone has the same problem or can point me in the right direction that would be highly appreciated!
