Just an update. I still have no flickering problems. I did notice that if I touch the cable that I'm using - a Kanex mini DisplayPort to HDMI cable - it flickers once. So I suppose that's just a connection issue, which is fine.
I also noticed that it does flicker once every couple of days, but it's just one flicker. So I'm thinking maybe the cable just moved somehow, or perhaps the problem still persists at a very tiny amount.
I really wish Apple would release a Thunderbolt monitor with a matte option.
WHy have apple only address the flickering issue with the 24" apple display? I get this all the time after i wake my computer up from sleep, Screen flickers, dims, picture on/off quickly..... my second monitor is a Dell 21". To be honest my issue is definately something to do with the wake up after sleep, but the 27" screen doesnt always feel 'solid' even now that ive stopped using sleep
Same here! Had to take my 24 inch Cinema Display to the Apple store, but they updated the firmware and its working great (Well as normal).
So for those of you with a 24 Inch Cinema Display that flickers on Thunderbolt. You will need to take you display to an Apple Store for firmware update. They no longer provide in online.
Even with all the latest updates on my 2011 Macbook Pro 13" running Lion my 24" Samsung external display flickers off and back on randomly when I am working. I have the right accessories and am setup the same way I was on my old Macbook which never had a problem. Seems to be a driver issue to me.
Hopefully this will be fixed soon.
since it required a firmware update to the 24" Apple Cinema Display (not the Mac itself) to fix the flicker, wouldn't it imply that Samsung is who has to issue the firmware update for you? Even as I type that it sounds weird...installing a firmware update through a Mac to affect a monitor...

I have the problem as Jeff Miller2 -- and the same configuration!
I also just updated to 10.7.2.
I also have the 20" Apple Cinema Display.
I also have a Mac Pro 2.8 GHz (2 x 2.8 GHz Quad-Core Intel Xeon processors)
I also have the Apple ADC to DVI adapter.
I have an ATI Radeon HD 5770 1024 MB.
At 1680 x 1050 the flicker is constant.
At 1600 x 1000 the screen bounces.
At 1280 x 800 about 5 rows of pixels at the top of the menu bar flicker.
I called ATI tech support and they said it's a driver issue and I should get a new driver from Apple.
If you're reading this because you have the same issue, PLEASE reply with a post to help document the issue so we might get some attention from Apple!
So after a day of the flickering, and trying everything to solve it, I have fixed mine at least for now.
I took the monitor cable from the Apple DVI/ADC adaptor out my MacPRO while it is on, right out of the video
card. Then I waited about 10 seconds and plugged it back into the video card.
Problem solved. I have not rebooted, no sleep mode and I have not logged out since doing this, so I do not
know if this fixed it for good.
So far it is back to it's good old self. Let me know if this works for anyone else.
You know the strange part. When it was flickering, exact same issues in same resolutions as the poster above with my configuration.
When I performed a software update to check for new software, the monitor was fine and the second it was done checking for new software, the flickering
camer back. Strange.
But right now it works. Maybe I'll reboot in a few days and be back to update this.
