hi,

i`ve read a lot about this issue, but i want to collect your personal experience.
in my case, when i put a external display on my macbook pro 13, eizo, apple cinema display, whatever... after max. 1 hour there is a freeze... most of the time with blue screens.

i`m in contact with apple but they don`t know what to do...

what the **** is wrong with our machines?

Not sure.

I hook up my 13" MBP to my 22" LCD with no problems.

Also my 42" LCD TV... no freezing issues.

Must be isolated to your machine
 
i think this is a well known problem to many macbook pro 13" user.
even the apple support forum is filled with issues like that.

maybe you are a lucky guy, you are even the first i know who can work with external displays without freezing system.

i don`t know if this is a hard- or a software issue.

could you post a link to the discussion on the Apple discussion boards?

I was having the same problem with my 2010 MBP 13" until I installed the new drivers from the iMac Graphics update, as did some others that I talked to on a German Forum. Now with the update everything is working again as it did before 10.6.4.
 
It must only be a problem with the 2010 models. I have a mid-2009 model and use a 24" external (ViewSonic) for 8 to 9 hours every day with no problems (extended desktop with both 13" and external). I use the mini-DP to DVI adapter from Apple.

Possibly, but it doesn't happen with all displays anyway. It worked fine with my old monitor, using a mini display port to VGA adaptor, and it crashes with my new one, regardless of whether I use DVI or VGA. Boo.

I have the 2.4 MBP 13" current model and have tested it connected to DVI, HDMI & VGA using the various adapters (all Apple adapters except HDMI) connected to Samsung 20" @1600x1200, Samsung 24" 1920x1200, Apple Cinema Display 20" @ 1680x1050, old 1280x1024 LCD and my 21" Sharp HDTV @ 1920x1080. No freezes or hangs after hours of use. I'm on 10.6.4 with 4GB Ram and Seagate ST9500420AS 500GB 7200 HD. There has to be something in common with the folks who are having the problem.

Cheers,
 
There is a thread on this on the Apple support website. Symptoms are very similar among users but no solution has been found yet. Apple is working on it, it seems.
 
Looks like the update just released (mentioned on Page 2) may fix this problem for those of you with Mid 2010 models.
 
I have my Macbook pro hooked up to a external monitor all day and have no issues. Using MDP to HDMI with 1080p output for the display.
 
mid 09 13" MBP 2.53ghz

mdp to vga with 22" acer, extended desktop with SC2 for 4-5 hrs a day.

No issues, good luck and make sure your software is up to date.
 
Try different "Refresh Rate" of the external monitor... I had this problem when I was using 60Hz... Now I'm using 75Hertz, seems fine~

Actually I had no problem whatsoever before when I was using my 17 i5 which I sold it~

So try the highest Hertz and see~ it might help...

Cheers
 
External display not waking up

:confused:It has become a major hassle in the past month. I don't put the monitor to sleep and have my sleep settings at 2 hours. I have to unplug the monitor in order for my Macbook (2008 vintage) to wake up. My latest "fix" is to change the refresh rate to 60, close the Macbook lid, and wake (sometimes) the external. The external monitor defaults to 75 and, if on, works fine until the next time it goes to sleep and then we start all over again. I use my Macbook as my desktop and well as my laptop. Frustrating.:confused:

If it freezes/hangs it should just stay on the last picture shown before. If it crashes/Kernel Panics it should show a log/dialog with the next login.

When you say "blue screens", what do you mean?
 
Hello everyone,

As mentioned above, I had the freeze problem with my MPB 13 and an external display.

Had the logic board of the MBP replaced (thank you AppleCare) and I have been working in extended display mode since this morning without freeze.

Prior to logic board replacement, the longest I'd worked before a freeze was 30 minutes.

So far, so good ! :)

Update 22/04/2012: Problem seems fixed for good. :)
