Hello i have the 15 inch mid 2010 macbook pro with sound support through hdmi to mini display port. anyway i bought the adapter for hdmi to play on your tv at the apple store. moshi makes it. everything works but randomly the screen flashes black for like a half a second. really annoying considering i bought the adapter to play movies through my computer on my tv. What's the deal? i have a 6 ft microsoft hdmi cord if that matters. my tv is a sony 52ex700. i tried switching hdmi slots on the tv too. also i changed the display from 1080p to 720 p and other display options and that didn't do anything. any help or possible recommendations would be greatly appreciated. update. audio skips about once every 15 mins too.
