    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.

    Check the HDMI cables, switch to a different one. I had the same issues and was able to find 1 out of 5 cables that worked fine with my Mini-DP to HDMI adaptor from OCW.

    i just tried three cables and they al did the same thing. one was a rocketfish cable which isn't garbage.

    Since you've ruled out the cable, perhaps you should inquire with the manufacturer of your adapter. Some adapters just suck.

    I have the same problem

    I have exactly the same problem.

    My MacBook Pro is mid 2010 too.

    The adapter is kind of a generic one I bought on ebay. Is your from Apple or some random seller?

    My cable is a 5 meters and the TV a Panasonic Plasma G Series Full HD.

    Any help is much appreciated (this is very very annoyng).
