Mar 22, 2011 8:53 AM in response to DanRybby Zebs,I can confirm this is still happening after 10.6.7!
I should say it happens a lot less often. For me it was constant blackouts, like 5 in a row every 20 min, and it would cause the fan on my display to go extremely fast for a second; and now its much less, like one every hour. I will call Apple Care to make sure they know the issue is still present. At least or me it did get a little better; but it is by no means solved! -
Mar 22, 2011 10:33 AM in response to DanRybby TJCacher,Same as most others - applied 10.6.7 to my 17" early 2011 MBP, and still have the jittery behavior several times per minute on my 24" ACD. Seems like it doesn't really get going until after the monitor warms up.
Still works just fine with my early 2009 17" MBP, running 10.6.7 as well. -
Mar 22, 2011 3:25 PM in response to DanRybby [LiQuID],10.6.7 had no effect for me, same blackouts continue every few min. -
Mar 22, 2011 10:25 PM in response to DanRybby leesilberkleit,!0.6.7 MBP 2011 15 2.0
Not many blackouts today but all of the sudden the screen became a mosaic of all the open windows. Unplugging and then plugging Thuderbolt connector fixed it. Hope Apple is taking notice of this....... -
Mar 23, 2011 1:18 AM in response to leesilberkleitby manomendip,Just to add to thread
I have same issue
Not fixed with 10.6.7 update
flickering very rare though - 3 times per day
blackout likewise rare 5 times per day
neither lasts more than a couple of seconds
so perhaps 30 secs of interruption per day.
Would prefer it to be fixed though! -

Mar 23, 2011 2:13 AM in response to DanRybby greubeuld,Hi,
I used to have a very similar issue with my late 2008 unibody macbook (first model with displayport coincidentally).
After a lots of months of tinkering, it appeared (and this is just guesswork) that the external display refresh rate was not properly detected, therefore the screen was trying to correct but would sometimes be out of sync.
There is an utility that allows to specify an arbitrary setting (SwitchResX) that fixed this for me.
Not saying this is the same issue, just thinking this is worth checking. Sorry if this been said before.
(NB the problem went away with later versions of Leopard ans an update to the adapter (came back after an OS update (maybe 10.6.3 ?)) -
Mar 23, 2011 3:48 AM in response to DanRybby El Presidente,I hope Apple realizes that this is still an issue and haven't checked it off as fixed...cos it's not. -
Mar 23, 2011 2:06 PM in response to DanRybby WylyQuimby,The 10.6.7 update seems to have improved things for me. I got one flicker this morning, but otherwise smooth sailing. Almost there anyway. -
Mar 23, 2011 2:36 PM in response to DanRybby jacblinde,Hi,
I received my new MBP 13" i7 five days ago. My previous computer was a 2008 MBP 15" coupled with an 24" ACD, and I had the black screen irregularly, approximatively three or four times per day.
But now, with the early 2011 MBP, things are coming to be crazy: the black blink occurred often, until two times per second! This morning, the screen became a mosaic, with the dock on the upper side of the screen. I made a screen copy and this copy was normal, i.e. the problem is in the display and not in the macbook. Just after, I unplugged the display port and replugged it: and all was right during several hours… Another curious thing: when I unplug the power cord, my MBP falls in a sleepy way…
I've had a contact with AppleCare, but they have no idea. -
Mar 23, 2011 5:52 PM in response to WylyQuimbyby RTJjr,The 10.6.7 update also seems to have improved things for me.
A few closely spaced brief blackouts and one flicker this morning just after I woke MBP from sleep. Nothing more thereafter rest of the day despite a variety of sometimes CPU demanding tasks. -
Mar 23, 2011 9:42 PM in response to WylyQuimbyby Kyle O'Bannon,Yep, I agree. I was initially worried once I noticed a blackout and a couple graphical glitches within an hour after installing the 10.6.7 update. It has been a couple days now and I haven't noticed any issues. So, at least Apple is on the right track. -
Mar 23, 2011 10:00 PM in response to Kyle O'Bannonby Kyle O'Bannon,Mother Hubbard! I must've jinxed myself. I just noticed the familiar graphical glitch. Still, it's a much less frequent occurrence. So, there's that. -
Mar 24, 2011 10:42 AM in response to DanRybby leesilberkleit,Yikes too!!
This morning had like 6 blackout blinks in less than 10 minutes. Last night had none in two hours.....
Then I though maybe the display connector was loose.... pulled it plugged it back in and bath screens were black (backlight was on, on the MBP)> Had to do a power on reset to get running again......
This morning I was running Chrome to check it out. I will try with no chrome for a while (may matter.... might not).....
24" is under AC and if this doesn't get better in a reasonable time Apple and I will have to have a serious talk....... -
Mar 24, 2011 11:39 AM in response to leesilberkleitby DanRyb,Add me back to the list! The night I applied the 10.6.7 update, I didn't have ANY flickering issues with my ACD. The very next day, and ever since, I still get them, pretty frequently still. Hoping Apple still sees this thread and realizes it is not resolved.
