Was wondering if someone can help me. I bought a minidisplay to HDMI cable for my MBP (1 week old). When i connect it to my Yamaha RX V667 receiver which is 1080p compatible, i get no signal, only when i put it as 1080i, which puts big boarders on the left and right side of the screen. I know for a fact the AV Receiver is 1080p as i have a bluray player connected to it. I dont want to run the cable directly to the tv because that would mean id have to use the TVs useless speakers. Anyone have any ideas?? Tried calling Applecare but the person on the other end of the phone didnt even know what 1080p was.
