22" Acer AL2216W Dual Monitor Set up - flashing - cannot wake from sleep

As a simple first step I'd reset PRAM…

It's drivers folks and Apple needs to update them. It's as simple as booting into Boot Camp (using XP Pro in my case) and using the latest video drivers. When the machine wakes and sleeps in XPP, no issues. Only happens with the Mac OS.

I've searched high and low for alternative drivers, but nothing. Until Apple provides a fix, we're at their mercy. Hopefully someone will do something about this. There's tonnes of articles on the topic that can be searched with popular search engines.

PS - Apple folks, expecting customers to return hundreds of monitors for a non-trivial firmware update (which won't solve the problem BTW, I've been through it 3 times now) is simply unfair. Find out what the fix was offered for Windows and apply the equivalent SVP. Thanks,

Just placed a call with Apple Support. Was getting "annoying" enough that I wanted to do something about this. Again, no problem when in Windows through BootCamp when monitor goes to sleep, just in the Mac OS for what ever reason with my Acer Monitor AL2616W connected via DVI (single-link cable). I 1/2 wonder if the monitor being capable of HDCP might be confusing the MacOS drivers.

I was advised that Apple isn't aware of this as an emerging issue (at least in their internal issue tracking system) and asked to take my computer and monitor into a service center. I can do that I suppose, just seems like a lot of work and lifting for something that's on a 6/10 on my annoyance scale 🙂.

Haven't decided if I'll do that just yet. Curious if anyone else has done the service center route. Part of me wonders if they'll just tell me to buzz off sine it's not an Apple monitor.

Really hoping someone has the gumption to do this and see if they can get something formal logged. I like taking the easy way 🙂. Maybe I'll wait until I have a day when I'm doing absolutely nothing and take the whole kit-and-kaboodle in for diagnosis. Until then, just figured I'd share my support experience.

PS - The apple folks were very polite and friendly. Just couldn't help me for something that's not on their radar yet. :/

Sorry do not have a solution but just want to say that I use 2 19" wide acers without any problem.

not sure if you have the same issue I had, but check this topic
http://discussions.apple.com/thread.jspa?threadID=1298090&tstart=0
then check your system log for the same errors

I have this exact problem. The only solution I have found is not to let the system go to sleep. Still have the problem at startup sometimes and it always happens if I manually power off one of the monitors. Tried PRAM reset. Tried some other reset. Tried Deleting the Apple Displays folder. Took it to the Apple Store and had the Head Genius look at it. Performed a system restore (will never do THAT again). Apple sent me a new video card. ALL IN VAIN! I have 2 20" ACER monitors and they work fine with this system.

Have you found anything else out?

I wonder if upgrading to Leopard will fix it.....

weird guys, my 22" inch acer monitors of the same make run perfectly with my mac pro 2.66 and a 7300 GT...

This is encouraging. I see that you are running Leopard. Did you upgrade from tiger or buy a new machine with Leopard pre-installed?

No sir, I upgraded from Tiger - carefully I might add, I still have tiger as a bootable backup on an external firewire disc. I did not have these two ACER 22" displays until I had already upgraded to leopard, but I have booted tiger twice since then and they work great.

Are you sure it will wake from sleep without any problems when running Tiger? If so, would you care to compare system profiler info? There has to be something different somewhere. I am running 4 GB of DDR2 667MHz RAM. 1 GB DIMMs in Riser A DIMM 1 & 2 and Riser B DIMM 1 & 2. My GeForce 7300 GT is in PCIe Slot 1 and its ROM Revision is 3008.

my ROM revision is 3011 for the nvidia. I have 3 GB of RAM, two 512 chips on riser a slot 1&2, two 1GB chips on riser b respectively.

Actually, I just put in another 2 to make 5GB 🙂

I had serious wake from sleep issues and found two conditions that contributed. One was having the USB cable connected to my EIZO monitor. Connect = problems, disconnect = radically fewer problems. The other was the use of a folder of .jpg images for my backgrounds. If I used them then I would get intermittent wake from sleep issues. If I "fixed" both issues my wake from sleep has disappeared entirely. I'm using a x1900 card. If you have a USB cable connected to your monitor you might disconnect that, zap pram etc and see if that helps.

No USB ports on these monitors. Running standard Apple images for desktop background. Tried running "solid colors" as the background. Didn't help. Thanks for the try though. Tried changing the PCI Express Profile to an x8 setup. That made things worse. Still hoping for an answer.
