10.9.2 update sleep issue with NEC monitors confirmed

After updating from Mac OS10.9.1 to 10.9.2, both my friend, who lives in another city, and I find that attempting to put our MacPros (2010, think his is a 2009 model) attached to a NEC PA 301 (mine) or PA 271 (his) series pro monitors to sleep experience a frozen screen and cursor followed about a minute later with an expected and desired sleep mode. My computer does something slightly different than his in that the background of the dock turns a golden yellow when the screen freezes. Both systems start up from sleep correctly.

If I only use my Apple 30 inch Cinema Display, the sleep mode works as expected.

Spent two hours with Apple Care (level one and level two) people that didn't have a clue what was going on. Called NEC and they had no explaination.

Any thoughts of wisdom of what is going on with the sleep issue that occurred right after we put the 10.9.2 update?

Mac Pro, Mac OS 9.0.x

I can confirm this problem with my MacPro 5.1 and a NEC PA302W display since upgrade from 10.9.1 to 10.9.2.

No workaround so far.

Here's another data point for the group.

I posted my experience earlier in this thread with a Macmini, PA271W, and 10.9.2, i.e. that the monitor will not go into display sleep under 10.9.2. I booted up 10.9.1 and 10.9.2 (as well as 10.8.5) and it was 100% repeatable that it did not work only in 10.9.2.

I have opened cases with NEC support and Apple, and Apple's has been sent to "engineers", but no reply yet. I was all set to believe it had to be an OS issue, or at least have an OS component.

However, I just purchased a Dell U3014, and it does sleep correctly with 10.9.2. This also is 100% repeatable: the NEC does not sleep, the Dell does.

I am not sure what to make of this, but it seems there might be a NEC component to this problem as well. There also has to be some change in 10.9.2 that brings the NEC issue out, though.

Similar scenario here: On my MacPro there is also a LaCie Photon18blue monitor connected - not affected by the upgrade to 10.9.2 - no sleep issue at all with the Photon18blue.

I'm having the same issue with 10.9.2 on my late 2009 27" iMac (iMac 11,1) all was well before 10.9.2 now my monitor refuses to go to sleep on it's own/after the time out period set in energy section. I've setup a hot corner to manually enable sleeping, but since that's a manual process, when I forget to enable it I'm slowly burning out my monitor. I've not tried an external monitor but it's happening with my built in monitor.

Is there a way to report/escelate this up to apple? do they read these forums?

Apple doesn’t routinely monitor the discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

Apple is monitoring this thread. An Apple Engineer emailed me and we chatted on the phone. I sent him diagnostic and system info. They are aware, for what it's worth.

Yep, another data point here, too. Early 2011 15" Macbook Pro running OSX 10.9.2 and an NEC PA271W... It was working fine until recently, must have had something to do with a background update...

Also broken on the 2013 Mac Pro with both a PA271W and a PA241 out of the box (the machine comes with a special build of 10.9.2). Awesome.

Mar 25, 2014 6:51 AM in response to LynnSD

This is also broken on a Macbook Air 2013. I am using 2 Dell external monitors connected via displayport. One is connected via mini displayport to displayport cable (sleeps), the other is using a USB 3.0 Startech to displayport adapter USB32DPPRO(broken). The monitor goes blank but doesn't sleep anymore.

This worked flawlessly in 10.9.1. So it appears the bug isn't related to NEC monitors specifically.

Being a recent Mac convert all these dual display bugs are really annoying...sorry but this kind of stuff just worked with Windows...

BTW I did send feedback to Apple for this issue.

I have been in contact with Apple Engineering, filed a report, and clicked an NDA so I can't really tell you what's going on right now. What I can say is that Apple knows about the problem and a fix should be out shortly.

Hi Guys,

does anybody have any issue with a NEC PA271W monitor connected with Apple Dual Lunk adapter to thunderbolt port where the monitor waking up from sleep (yest, it wakes up) as a terrible snow effect and or all the images misaligned.

Need to turn off many times the monitor and/or disconnect the thunderbolt (minidisplay) cable from my new MAC pro. Very annoying. The same was happening with my Macbook Pro....NEC also changed my monitor.....same issue!

Regards!

Vic!

Yup, same issue. It's not your display. Unplugging the Mini DisplayPort fixes it for me every time...however, I'm just using the Mini DP to DP cable for now and shutting the display off...less annoying than using the Dual Link DVI adapter. I've been told that the issue with the Mini DP to DP cable on NEC displays is fixed in the forthcoming 10.9 update.

Apr 27, 2014 10:09 AM in response to Vic!

Hi Vic,

thank you for yor message. Yes, that is really annoying....I was thinking to buy a different brand MDP dual link dvi adapter but I am worried I may have the exact same issue...

Even tried a HDMI to DP without seccess... ahhhhh...

Apr 27, 2014 3:32 PM in response to LynnSD

I have confirmed that the issue is resolved on the upcoming 10.9.3. Just be patient. Or sign up for the seed program that is now public, and grab a 10.9.3 beta.
