30" HD Cinema Display with Mini Port to Dual Link DVI Adapter

Usually this is due to a faulty Mini DisplayPort to Dual Link DVI Adapter.

I had the same problem with my new new MacBook Pro 17", 3.06 GHz with 8GB of RAM when connected to my 30" HD Apple Cinema Display. I saw visible horizontal flickering lines on the ACD screen, especially in black backgrounds. At other times I would see bizarre green lines. Refreshing the ACD at various resolutions etc did not fix the problem. I went to the Genius Bar and we tried a new Mini DisplayPort to Dual Link DVI Adapter to connect my MacBook Pro to a 30" HD Apple Cinema Display at the Apple Store and it worked perfectly. Apple replaced the Adapter without any fuss and I have had no problems since with my MacBook Pro connected to my 30" ACD.

I have tried 3 adaptors, both firmwares, didn't solve the problem.
Bought 2 new displays.
Problem solved.

I had the same problem when connecting to my new Mac Mini with the $100 Dual Link adapter.

I would get the vertical white snowy lines with red and green striped, and the fix was to check the resolution. This occured after I was in sleep mode after watching my Elgato Eye TV video.

Your choices for native resolution are: 2460 x 1600, 2048 X 1280 or 1920 X 1200.

hi everyone, I am getting the following as well as flickering sometimes:

1/ Bluetooth disconnects and it won't connect without a restart
2/ kernal panic
3/ bluetooth mouse goes craze, move mouse to right adn cursor goes left! basically opposite happens
4/ as point 3 above, but nothing is clickable, as if its frozen but the mouse kind of works
5/ everything freezes

I am getting the feeling that when its not connected to my new macbook pro unibody, and just running the laptop on its own, all is fine, testing it now........

I'd love to know why my MacBook Pro will automatically and immediately produce a perfect full-resolution image on the 30" Cinema display when I'm running Windows 7 under Bootcamp, but in OS X.5.8 the display isn't even detected by the OS. "Detect Displays" does absolutely nothing.

Maybe I spoke too soon.
I've been having the stripes problem (intermittently)for several weeks.

I went to the Apple Store and they replaced the Dual-Link adapter since although photos with my digital camera showed the stripes with red, green, black lines, dual cursors, and difficulty in reading the menu bar, I also was able to launch Utilities->Grab and took a screen shot which did NOT show any problems on the screen.

This behavior occurs randomly, sometimes not for a day or two, sometimes 3 times in a day.
It has been cleared up by Restart.

This always occurs after I used a Hot Corner -> Sleep Display.

Although I was there today, I have to bring back the Mini, Dual-Link adapter, and the 30" ACD.

I'll probably have to leave the computer for a couple of days as they try to figure it out.

So, IMHO, they don't know what this quirk is all about.

Any ideas?

I have a brand new MBP 17" with an 3 year old 30" screen. Just bought a Dual-Link DVI adaptor with 1.02. I see plenty of flickers... very annoying. Guess I'll be calling Apple tomorrow.

mine actually crashes, so its not just the flickering. I am on my second replacement adapter 😟

Did anyone every find a resolution to this issue? If so, please post the solution. Thanks Mac Family!

Did somebody already try this other (and only one, as far as I know), Mini displayport-DVI adapter ?

They say it works with the 30".

I'd love to buy the new Mini with a 30" but I'm just too scared by this bug for now.

Hello All,

I'm waiting for a software solution from the Apple technical center. I called Apple Care one month ago, and the tech said that I should be very patient ...

I described in the Mac Mini section that I have encounter random flickering problems when the Mini comes out of black screen or sleeping...

Thus, I have found a post from someone who solved the problem by replacing the 30" ACD by a new one.

It was with a MacBook Air laptop.

Here is the link : http://sandro.knot.org/blog/?p=919

Of course, it's Apple who changed the display on it's own.

I really get eager to have a computer working fine !

so - why can apple make 30" display that works, but they can't make a 27" display that works?

I have the same problem with my brand new 2.66GHz Unibody 15" Macbook Pro and my 4-year old 30" Apple Cinema HD Display. The Dual-link DVI adapter firmware is v. 1.02

The problem is the same with 9400M and 9600 GT display cards: Any large black area on the 30" screen has horizontal errors in it. Opening a black web page like MobileMe gallery will immediately result to this:

I think zapping the PRAM and/or resetting the SMC took it away for a short while, but it always comes back.

Doesn't matter if the Macbook Pro is connected to a power outlet or not, or does it have any external devices connected to it. It always happens.

Any news about solving this issue?

Plussa,

I looked at your you tube video, and had to reply. I have exactly the same problem, but it is with a 30" apple monitor hooked up to one of the first intel mac pro's. I've tried everything to fix it, new brick transformers, different cables etc, and it's still there. I was just so amazed that someone out there has precisely the same issue. I've been on to apple about this but because the screen is four years old and I live in the UK where apple have a policy of 'no serviceable parts' to these screens I was basically told to go out and buy a new one. Shame on you Apple. I'll just have to live with it for now but just wanted to let you know that it's not confined to the macbooks. Personally I think its a manufacturing fault with these screens. If enough of us got together with our serial numbers and went en masse to apple perhaps we could get a result.
