periodic Dual-link display problem with new adapter

Could you tell me where you got the firmware update for your adaptor? I cannot find it in support. I have had two adaptors. The last replacement was sent to me in something like Feb. and I have not been able to use it.

Hello,
How do you confirm the firmware version of your adaptor? I have read that the new version and 10.6 works. I have installed 10.6 and would like to use my 30" Dell.

I have the same periodic problem with my dual-link display adapter used between a new Mac Mini and the Apple Cinema 30" HD display. Every 15 minutes or so it drops the display for 1/2 sec and goes black or it gets completely fuzzy and then snaps back. No issue ever encountered between a Macbook Pro and the 30" display with the standard connection.
Now with Snow leopard it can "hang" in this fuzzed state and require shutdown and rebooting, so the issue is getting worse not better. I love Apple products but this issue should be taken seriously by Apple and solved!!!!

Reading that snow leopard + firmware 1.0.2 might actually (finally) solve this problem, I called Apple to try and get my old one swapped. They of course didn't know anything about this problem supposedly. Also, weren't willing to ship a new adapter, since they weren't sure what firmware was on it. I didn't want to get a refurb with the old firmware, so now it's to an Apple store to swap it. Lame.

Please let us know of any updates. Cause I got the 1.01 and 10.6 and it seems to have gotten more frequent. Basically every time I leave my computer for more than 30 minutes, when I come back my display is messed up and reboot is the only fix.

1. How can I tell what version of the dual-link display firmware I am running?

2. Where can I get version 1.0.2?

Thanks.

1. In the System Profiler. Its already been said multiple times in this thread.
2. By getting a new adapter, but its not printed on the box, so you have to go to the Apple Store, get a replacement and test.

Where in System Profiler do I find the version of the firmware? System Profiler is huge.

Or to ask a different question, how do I search inside this thread for System Profiler to find the right answer? There are almost 200 entries in this thread.

Thanks.

hah. why don't you just use your browser search and search for "Profiler" and find it. it took me all of 10 seconds. instead of this thread being 200 posts, all with 50% REPEATED questions.

Thanks for providing the link. Using the link, I found the answer.

I also searched for about another 15 minutes and didn't find it on my own so I'm glad you provided the link. I'm curious how you found the answer in 10 seconds. Did you search with Google, or with the Apple Discussions search? What search terms did you type?

This is a first test of the adaptor with a confirmed 1.01 frimware and snow leopard. At first it was fine. Then I logged in again to use the superior graphic chip. It then failed as expected. However I could not read an automatic update which I went ahead and installed. I then logged in again. And for now it seems fine. I am not confident that all is fine since I have had this problem since early December last year and have not been able to use this machine. If all goes well over an extended time I will report.

One very weird thing I just noticed. I went to about this mac and checked the graphic/ displays. Now I see on my 30" Dell this:
NVIDIA GeForce 9400M:

Chipset Model: NVIDIA GeForce 9400M
Type: GPU
Bus: PCI
VRAM (Total): 256 MB
Vendor: NVIDIA (0x10de)

Obviously I am connected and I am using the adaptor as I type and read on my large monitor. Weird!!!

Woops. I also get this:

I had hoped the problems were solved. But as usual since I bought this machine in December of '08 its a clunker. Of course after about an hour the bad and the ugly reared it's Steve Jobs head with fuzzy snow the whole bit. So no; Snow Leopard does not work with the adaptor firmware 1.01. What I hate is now to get apple to give me the proper firmware. I have paid for the computer and adaptor. But the problem has been going for 9 months and the last ( second) adaptor was sent to me some 6 -7 months ago and has sat unused. What is the bet they will not make this easy for me?

So what did you do? I am in exactly the same position. I have the same set up and have a' new' adaptor what does not work either. Were you able to get Apple to stand by their equipment?

What's even more depressing, I've open a bug report on this in February with Leopard, it didn't even get acknowledged in 8 months. Now I've opened one for Snow Leopard.

I think I am going to call Apple Care this weekend and see what my options are from them, since I absolutely hate dealing with the Genius Bar. I don't feel like spending my Saturday afternoon trying to PROVE my problem to a genius bar idiot.
