    thanx for the info mate.

     

    My monitor (a 19" AOC) is dual input : VGA and DVI-D.

    I used so far a DVI-D to HDMI connected on the mac mini.

     

    Yesterday I used a DVI-D to DVI-D, that came with my monitor, with the mac mini's HDMI to DVI-D, I had zero issues with the display.

    Well, the DVI-D to HDMI cable that I was used was something generic.

    The original DVI-D cable that came with the AOC has ferrite rings on both connectors.

     

    I also set the monitor to have the DVI-D input as default  (not AUTO mode between VGA / DVI-D)

     

    thx

     

    chris

    That's good. I use also the same cable DVI-D - DVI-D that came with my monitor, with Mac Mini original adapter and it works perfect.

    And a bronze ring round your left ankle?

     

    Seriously, though: I know ferrite (or powered iron) rings used to be used to reduce radio interference. But are ferrite rings actually incorporated in some monitor cables? How can one tell?  Some USB cables have cylinders about 1 cm in diameter and 3 cm long near one end. Do these contain ferrite? I have always assument that they are purely decorative. But I have never seen anything comparable on a monitor cable. I should be very grateful for elucidation.

    I prefer silver rings

     

    Monitor cables have those cylinders, the decorative ones as you say - in your case.

    I can't afford silver rings. I've spent too much money on cables and adaptors.

     

    But it's still not clear to me: are those cylinders ferrite rings or are they just decorative?

     

    In my case, as a matter of fact (as I said in earlier posts), I am currently not having the black screen problem at all any more. But in the maze of possible causes for the problem — graphics card, RAM, cables, adapters — all I can say is that removing a couple of old screensavers from my system and replacing the monitor's HDMI cable and Apple DVI-D adapter with a quite cheap DisplayPort to mini DisplayPort cable — without cylinders, ferrite or plastic — seems to have cured the problem. I'm not superstitious. I don't believe in ankle rings of any composition. But I'm touching wood!

  • theo2ro Level 1 Level 1 (15 points)

    100% decorative for you, and ferrite rings for others.

  • Michael Graubart Level 2 Level 2 (250 points)

    Help! As I said in earlier posts, I seemed to have solved the black screen problem by changing from HDMI to DisplyPort cable and deleting two old screen-savers. Suddenly I am in serious trouble. I should be very grateful if other contributors to this string could tell me whether what I have now observed is the black-screen phenomenon that the posts have been about, or whether my computer is now suffering from something else.

     

    1. A few days ago the computer would not start up properly. It kept bleeping, the white pilot light blinked, the screen went black but with a lot of incomprehensible white text. I had to turn the computer off with its start-up button. I waited, then restarted. A similar situation occurred, but without the white text. The third time I tried, it started normally.

     

    2. Today, while I was doing something quite simple with Bento, the screen suddenly went black and the computer bleeped rhythmically again. After I had switched it off by the start-up button, a crash report appeared. I tried to copy it, but in my panic must have not pressed a key properly, because I have not got it.

     

    3. A few minutes later, however, while I was writing an e-mail in SeaMonkey, everything crashed again — but left me with a white screen this time. This time I was able to copy the subsequent crash report. Here it is:

    I should be immensely grateful to be told whether these disasters are the ones this string is about (in which case I shall eventually have to sell the computer and buy the 2013 version) or whether they are a different phenomenon, in which case I might be able to get the computer repaired under guarantee.

    I have a feeling this driver causes troubles...

  • Michael Graubart Level 2 Level 2 (250 points)

    Thanks for this, Chris Syntichakis. I shall have to try uninstalling everything connected with Soundflower. But why would this small application, which is no more than a switch that allows a sound source like a browser to be connected to a sound recording application like Audacity in order to allow recording of an audio stream from the internet, cause such trouble? I shall be sorry to lose Soundflower, which, as a musician and lecturer in music, I find very useful on occasion. I have, in fact, not used Soundflower for at least a week.

     

    So you think this is not the black screen fault about which there has been such massive posting in this discussion?

  • Michael Graubart Level 2 Level 2 (250 points)

    PS: I have just looked at the Soundflower forum, and it is full of stories about computer crashes.and panics. I shall uninstall Soundflower, but the curious thing is that I have had Soundflower (and occasionally used it) for a few weeks, and the crashes have only just started. Still, i shall try.

     

    Thank you again very much indeed, Chris Syntichakis, for putting me onto the trail.

  • Chris Syntichakis Level 1 Level 1 (0 points)

    Just give a try, without this driver. I understand you need it, I just visited its page on google.code, well  : released Aug 2012 ! Probably was compatible with earlier versions of ML

  • Michael Graubart Level 2 Level 2 (250 points)

    I've cleared everything to do with Soundflower out now, so I'll do without it (I can work round its absence) for a while and see whether my crashes and panics have ceased. Then I might try re-installing it but (as you suggest) removing that driver. But will it work without its driver? Remains to be seen.

  • Michael Graubart Level 2 Level 2 (250 points)

    Following from above, this morning, shortly after I had started my computer and was looking up some websites, my screen went black. Pressed and held start button: computer went into bleeping mode. Tried several times, eventually started and showed a white screen with the following message in white text on a black band at the top of the screen:

     

    Panic(cpu 3 caller 0xffffff00040b8655): Kernel trap at 0xffffff0004087ca3, type 14=page faul regist rs:

     

    Restarted yet again; this time OK. No large error report (as before) appeared.

     

    There seem to be 2 possible explanations:

     

    This seems not to be the 'black screen' problem documented in hundreds of posts here. It is a CPU problem.

     

    Though I uninstalled Soundflower completely yesterday, it may have affected my system permanently. There is some evidence of this happening to other people who have installed and uninstalled Soundflower. Please see

     

    http://code.google.com/p/soundflower/issues/detail?can=2&start=0&num=100&q=&cols pec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&groupby=&sort=&i d=113

     

    Please can someone tell me what to do? Should I reinstall my whole operaying system (10.8.4)? Can I obtain a fresh one from the Apple Store? Is installing it straightforward?

     

    Thank you in anticipation.

    Yes, you can get the OSX from USB, I used this guide to have an installation OS from the USB:

    http://appducate.com/2012/12/install-os-x-mountain-lion-from-usb-flash-drive/

  • Michael Graubart Level 2 Level 2 (250 points)

    Thanks very much once more, Chris. I downloaded Mountain Lion (not without difficulty: the download failed and I had to repeat), made a copy of the installer so that I can reinstall yet again if need be, and so that I can install the OS onto a flash drive as per the instructions you kindly referred me to as soon as I have time, installed ML in my computer — and now have to wait a few days before I can begin to be confident that the problem is cured.
