    Hi, long time lurker, first time poster.......

    I have a 2.26 Quad Core Intel Xeon, technical info:

    Model Name: Mac Pro
    Model Identifier: MacPro4,1
    Processor Name: Quad-Core Intel Xeon
    Processor Speed: 2.26 GHz
    Number Of Processors: 2
    Total Number Of Cores: 8
    L2 Cache (per core): 256 KB
    L3 Cache (per processor): 8 MB
    Memory: 6 GB
    Processor Interconnect Speed: 5.86 GT/s
    Boot ROM Version: MP41.0081.B07
    SMC Version (system): 1.39f5

    I have recently had to downgrade(?) my monitor from a 2007 23" Apple Display to an LG E2350. Since then I have been suffering from some serious video playback/stuttering/crashing issues in both adobe premiere and in pro tools/logic when working on sound for picture, to the point that I cant actually work on the project. This problem occurs when the monitor is connected by both mini-display port > HDMI and when it is connected by an apple dvi > vga adapter. The problem is also not file size dependent.... I have the same problem if the video file is 1gb or 10mb.

    The ONLY difference in my setup is the monitor. Prior to the downgrade there were no problems what so ever and everything ran perfectly.

    Can anyone help a not-so-video-tech-savvy brother out?

    Sounds to me like your GPU is going bad, and the display just happened to be at the same time. Have you tested the Monitor on another machine? (Even a Windows one) if possible using the same adapter to see if it has the same result. (And that must be an absolute PITA if it goes during a ProTools session...)

    Thanks for the reply Chrismacguy.

    I haven't tested the monitor on anything else, I'll give that a whirl.

    Not sure its the GPU as playing a clip or trimming in quicktime or i-movie is fine, its only happening when I try to perform basic functions such as trim/scrub in my prosumer apps that there is a problem......

    Apple has had miscommunication problems with monitors before. The solution could be as simple as replacing the monitor. Guessing that the GPU is going bad maybe premature. Although, it is interesting that even a VGA connection is flaky.

    OP, if you can borrow someones monitor, give that a try too.

    If you can't resolve the problem then it is time to pack up the box and let Apple diagnose the problem.

    I said GPU since VGA is flaky. If its the monitor, it tends to be either obviously the screen (Lots of pretty colours), or no picture. No monitors internal hardware can cause just a video to stutter. Only the GPU can do that. ergo Dying GPU.

    Thanks for the insight so far guys.

    I will test the monitor on the wife's macbook, see what result that yields.

    The only other thing that springs to mind is the fact that the monitors drivers/software are windows only and obviously cant be installed on my machine. Could that be a potential culprit?

    Should have just forked out for a new apple cinema display, at least you know everything's going to work then.

    No, the "drivers" tend to just be a color calibration utility and maybe the ability to change a monitors brightness from software - there are no required "drivers" for monitors, otherwise they wouldn't be able to display BIOS screens on PeeCees.

    Right, gotcha.

    Well I plugged the monitor into the mac book pro, and again I was able to edit/scrub in i-move/quicktime with no stuttering video or audio issues and no hangs, which I can also do on my machine. I don't see why everything works fine in those two apps but not in premiere/PT/Logic?

    I am going to guess it's something else... can you answer these questions please:

    How much free disk space do you have on the boot partition?

    Do you have Perian installed?

    Do you ever see odd slowdowns with anything else or is it just those apps?

    Do you get a slowdown when you run HD videos from VLC ( open source video player )

    Do you have any less of a slowdown when you start a new project with Premiere and have nothing

    Hi Huntercr, thanks for replying.

    1) 417.29 GB on the boot drive. 499.76 GB on project drive 1 and 999.86 GB on project drive 2

    2) No

    3) No slowdowns on anything else, just the mentioned apps.

    4) I don't have a blu-ray player installed so no true HD. None of the movie clips I use are in HD as far as I am aware. Playing back a DVD from the DVD drive results in no problems what so ever.

    5) Pro Tools & Logic both behave as expected when working on projects that have no video associated with them. Premiere, PT & Logic all only start acting up when video is added.

    Could be...

    You could have many issues going on at once or just one causing it all.
    Ive had similar issues with different gear at work/home.
    Which video card are you using?
    A few times on Avid workstation, QuickTime has been the main culprit.
    When video was introduced in ProTools years ago(v.o. sync), our problems occured mostly on the QT end.
    The only time Ive had a monitor cause pain in the workflow was using a Apple Cinema 30" on a low-end display card. Fixed all that with recent cards but now the new pain is adding a Gefen 2x2 DVIDL switcher in the mix :p

    Thanks for the replies everyone.

    I just performed the apple hardware test from my OSX install disk and no hardware problems were reported.

    I have backed everything up and am about to embark on a reformat as I have really exhausted my (limited) knowledge and patience on the matter, I just want to be working. If this solves the problem, great for me, but it would of been nice to know exactly what was up. If it does not work, I expect I will be back.........

    Thanks again.

    Did you try changing the resolution to different settings? If you still have the bigger monitor, did you try using that to see if your still having issues? You didn't by chance unplug the monitor while it was still on?
  15. alexonamac thread starter macrumors newbie

    Apr 19, 2011
    I did try different resolutions but it did not resolve the issues. The old monitor died completely so I couldn't perform that test. And no, I did not unplug the monitor whilst it was on.

    The reformat seems to have done the trick, unfortunately that leaves me none the wiser as to what caused the issue in the first place. However, since reformatting, re-installing everything and updating everything I have had 2 crashes in the space of a day. So something still isn't right.

    Anyone any good at reading crash reports want to tell me what the hells going on? :D

    Are you trying to run Lion (OS X 10.7)? If so, send this feedback to Apple and then downgrade to the current version 10.6 for production.

    Also, it is interesting that the backtrace is displaying a lot of information for graphics, your problem.
  17. alexonamac thread starter macrumors newbie

    Apr 19, 2011
    Hi xStep,

    Nope, I am on SL 10.6.7 which was installed via a combo update from SL 10.6

    I was having some issues with the software required for my iLok, I re-installed the drivers/repaired permissions/trashed relevant prefs etc, and everything seems to be Ok, for now.

    Can you explain what the backtrace means, and more importantly what it is saying about my graphics (card?) I would really like to get to the bottom of this and any help I can get would be really appreciated.

    Can't tell much about the back trace. The idea of a backtrace is to list the instructions up to the problem instruction. Unfortunately those jumble of numbers aren't helpful since they don't link back to a symbol table. All we can gather is pretty much in the "Kernel Extensions in backtrace" section.
