So I want to use my tv as a screen from my MBP, so i cant watch my movies on the big screen. I know i have to have Mini DP to HDMI, then a HDMI cord from that to the tv, i understand that. But what about sound? If im right the mini DP to HDMI doesnt carry the sound cause of it being early 09' model? Correct? Thats really my main question, if so (that i need a cord for the sound) what kinda cord?
