I've got a MacBook Pro 2011 with OSX ML (All up to date). SInce I've had it and used it via the TB -> HDMI (used several cables which are Apple originals) THe HDMI flicks out and back in again as if I've opeed the lid.
The main reason why I say this is because the Apple on the laptop in ClamShell mode flickers (as it does when also wake the notebook in clamshell with the HDMI connected).
I've got a Samsung television about 5 years old, which works fantastically with the myriad of other HDMI devices I have connected to it. The only issue seems to be the MacBook.
Here are my Settings & Preferences:
Resolution: Best for Display (I've also tried the Scaled too)
Refresh Rate: 60 Hertz NTSC
THis has happened on OSX 1.06, .7 and now ML. On other televisions I don't notice this issue at all, itonly appears to be with this one in particular.
I've had a look at Console and trauled through the logs when it happens, and all I can see is that the display, momentarily can't be found.
I can confirm this doesn't happen in BootCamp Windows 7 Pro x64, so I'm at a loss as to what to do.
The sound works perfectly, though once in a bluemoon I get a weird 'stutter effect' where the stutter gets slower, and slower until the sound vanishes. THe only way to restore the sound is to flip input to another or turn the TV off and back on again.
Is anyone else experiencing these issues?
The ONLY thing I can think of which differs on this TV from my others, and those at friends houses is that being Samsung it has something called Anynet+, which is like Toshiba's Regza and Sony's Bravia. Which works find with my sound systems, IPTV box and the other devices.
