I have just bought a new MacBook Pro (OS X 10.8) and try to connect it to the HDMI port on my Sony Bravia KDL-40EX710. I get a clear picture of the computer screen on the TV, but every 1-30 seconds the TV screen becomes black for about 1 second. I tried the same thing on another Sony Bravia TV with the same result. When I tried it on a Samsung TV everything worked fine without interruptions.
Does someone have a solution to this problem?
