Currently Being ModeratedMay 12, 2009 3:19 PM (in response to Viridiana)Over time have seen the horizontal line pixel static distortion problem
on DVI dual linked 30"ACD especially
when using remote login to another computer.
The new OSX 10.5.7 does not fix the problem.2GHz G5 mac pro, core 2 duo macmini 2.26 Ghz, Mac OS X (10.5.6), 1st computer was an Imsai 8080 I built
Currently Being ModeratedJun 18, 2009 2:43 PM (in response to Cordwainer)Called Apple Care. Said take it to store.
At store uploaded the Bluetooth 2.0 firmware update.
Could not reproduce the horizontal lines on a 30" ACD
with original Dual link DVI cable with firmware rev. 1.01.
Genius also swapped out my Dual link cable with 1.01 firmware
for a dual link cable 1.02 firmware.
Could not reproduce the problem at the store with either cable.
Took Mac mini back home with 1.02 cable.
No more horizontal lines.
Problem solved but can't figure out if it was the bluetooth firmware upgrade
or the dual link DVI cable with upgraded 1.02 firmware.
As far as I am concerned this thread can be closed.2GHz G5 mac pro, core 2 duo macmini 2.26 Ghz, Mac OS X (10.5.6), 1st computer was an Imsai 8080 I built
Currently Being ModeratedJun 18, 2009 6:51 PM (in response to Cordwainer)Good information but I actually see three things that could have fixed the issue:
1) Bluetooth FW update (considered least likely to me but we should know soon as others apply it)
2) Dual-link adapter FW from 1.01 to 1.02 (seems more plausible)
3) Swapped one adapter for another (could be most likely reason for fix)
Prior to the adapter FW update, other users reported fixing the issue just by swapping the adapter for another one. So that act alone may have been the fix, regardless of the FW level.
Currently Being ModeratedJun 23, 2009 8:56 AM (in response to BSteely)it's the firmware. i tried everything and nothing worked until i got 1.02 cable. however - satisfaction short lived, as i now notice significant screen response lag, e.g. moving windows around or typing fast, it is slow/jumpy. anyone else see this problem? not sure how to test/prove to apple...Mac Mini 2Ghz Intel Core 2 Duo, 4GB RAM, Mac OS X (10.5.7)
Currently Being ModeratedDec 3, 2009 7:00 AM (in response to Viridiana)Hi,
I stumbled across this thread while looking after a sync problem in exactly this setup:
Mac mini from April 09 / Mini DisplayPort To Dual Link DVI Adapter FW 1.01 / ACD30 (2008)
a) Picture disappearing for a moment (screen going black an reappear in about a second),
happening several times a day, up to several times per hour
b) Vertical stripes in picture, typically after system went to sleep an i woke it
-> garbled login screen
b) unplug USB connection between Mac mini and DP/DVI adapter
1. Checked an lowered Mac mini temperature (Fan control)
-> no improvement
2. Cooled adapter (real fan )
-> no improvement
3. Swapped adapter (again FW 1.01 - thanks Rüdiger W. from the Bense Team Dortmund)
-> no improvements
4. Set up separate USB power supply to 1.01 adapter
-> no improvements
5. Ordered a FW 1.02 adapter from Amazon (since Bense Dortmund quit supporting me meanwhile)
-> both problems solved
I didn't check the new adapter without separate USB supply.
I am finally happy with the setup, yet lost my Apple dealer on the way
This was by far the worst experience with any Apple product.

Currently Being ModeratedDec 12, 2009 6:52 AM (in response to alterschwede)Hello
I bought a few weeks ago the Mac Mini Late '09 with the Adapter Rev 1.02 in order to use my ACD 30".
I would be fully pleased if I didn't experience the random screen problem following:
Those screen problems appears randomly (not each time) when my Mac is just woken up.
Does anybody encounter same screen problem ?Mac Mini Late '09, Mac OS X (10.6.2), Cinema Display 30"

...a little late, sorry: your image distortion is exactly what happened to me while using the 1.01 FW adapter. My problem was solved by providing a separate USB power supply to the FW1.02 adapter. Maybe you just try this - these USB power supplies are dirt cheap. You'll lose the USB ports on the monitor, though.
