Guys, I just linked my brand new iMac to my Sony Bravia HDTV (32D3000) using a mini-DVI/VGA connector and a VGA extension cable. However, my iMac doesn't detect my HDTV, and only says "VGA monitor" and offers me resolution up to 800x600 60Hz (the native res of my TV is 1366x768) !! What can I do to make it work ? It was working with my 2-year old MacBook, so I thought I'd have no problem doing the same thing with my iMac. Btw, I got the 2,66Ghz model. Can you help me ?
