24" LED Display with 2011 15" MPB

Hey all,

I've had this 24" LED Cinema Display since it came out and have been using it with a 2010 MBP until now - I upgraded to a 2011 15" MPD (2.3 Core i7 with high-rest matte display) and now with this new MPD, I intermittently get the 24" LED display turning all black before going back to showing my display. It's happening pretty often. Is anyone else experiencing anything similar?

MacBook Pro, Mac OS X (10.6.6)

You're not alone. I just noticed the first blackout since installing 10.6.7 at about 40 minutes after boot. The only apps I had open were Mail, Safari and iTunes (nothing playing). I haven't noticed any graphical glitches (yet), though.

And... I just noticed a graphical glitch at 59 minutes since last boot. Bummer.

Updated to 10.6.7 last night (Central Europe), and worked fine for hours (as it sometimes did before), and then today, up until just now (noon): flickering and blackouts just as before, on a 24 inch ACD that worked fine with MBP's prior to Early 2011 MBP's.

Edit: I did reset PRAM after the update and before hooking the laptop up to my 24 inch ACD

Edit 2: I notice this other very strange behaviour, ONLY on days when I've been having these glitches and blackouts. In Safari (5.0.4), when I'm on a website, and click on the bookmarks icon, and whatever is highlighted in the navigation column of bookmarks doesn't have anything in it, so that the cover flow section is supposed to be empty, this "empty" field does not refresh into the black it's supposed to be, but stays on the website as it is. Anyone else have this when they try?

At first after updating, I wasn't able to duplicate the problem, and now, just when glitches and blackouts started again, I'm easily able to duplicate it. See here:

Thanks for the link. I'm pretty sure that's not me though. I should have said jitter, not flicker. I have the issue of 1 second blackouts and a digital looking jitter that quickly shifts the external monitor's content to the left or right for a split second. My Apple 24" display worked just fine on my last unibody MBP, but the newest one with the thunderbolt port seems to have issues with my apple display. The display is perfect when hooked up to my other macs. Thanks for the post, it really helped to read that other thread though.

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!
