    TO ALL:

     

    Please note that the Intel forum posting that had acknowledged  the flickering problem has been substantially amended... It basically now say go ask the OEM... It's meaningless now!!

    It doesn't really matter what Intel says. It's what Apple says that is important and they are saying "...............

    LOL Seriously, there is no need to panic and blow this out of proportion. The change in the post simple indicates that Apple has the Intel drivers and are in the process of testing them. Most people already knew this. 10.8.3 has already been seeded, and developers are in the process of beta testing.

    I'm thinking this may mean that Intel have done their bit and now it's over to Apple to reassure their customers that they're on this. On the other hand it could just be passing the buck.

     

    EDIT-----

     

    Apparently not, Intel say they have indeed done their bit: http://www.theregister.co.uk/2012/11/30/intel_insists_mac_mini_hdmi_fix_inbound/

     

    Maybe good news for those of you that hung on to the 2012 mini.

    Quote: Now the flicker issue is one thing, I hope they also correct the wrong color profile for HDMI. (washed out light colors) This is as important to me as the flicker issue. But I'm sure you folks will report the results once 10.8.3 is there.

     

    Hi Fellow Belgian,

     

    I completely agree on the Flicker issue, they should provide a solution soon or give me my money back. But the washed out colors via HDMI is a simple matter that you can easily remedy yourself. I did, just use the Calibrate function under Displays->Color.

    Hi 77slevin, sorry for the late response.

    I stopped checking this thread everyday, since I went for the refund. But I've followed & participated it from the beginning, I've read all 43 pages over the past month, and although it is not as widely reported and documented, it is also a Intel HD4000 issue, and I've seen it reappearing occasionally.

    (you can read a more specific explanation of my issues on page 10 of this thread, my second post on that page.)

    Here are other threads about this specific issue:

    https://discussions.apple.com/thread/4480354?start=0&tstart=0

    http://forums.macrumors.com/showthread.php?t=1482487

    there are more, just google , I didn't bookmark 'em all.

    Conclusion:

    Colorsync calibration improves the overly saturated default profile a bit, to more or less acceptable, but by no means I can obtain the same image quality I have when I connect the same monitor with my 2010 MacBookPro (discrete nvidia gpu)

    You can calibrate until your socks fall off: the very light colors remain unvisible, and colors seem a bit unnatural.

     

    The reasons I think this is less reported are

    1) many people don't even notice because they have only one monitor set up, it's more visible if you compare in a dual monitor set-up. The HDMI output is more saturated and has crushed whites.

    2) It's also possible that it is brand dependent, I have two samsung monitors, maybe people with other brands have another default color profile, don't know, did not receive much feedback on this secondary issue when I posted it (page 10). Luckily above mentioned other threads confirm that I'm not the only one, and I could cancel my appointment with the eyedoctor ;-).

    3) people are so used to overly saturated colours on their TV-sets, that they don't notice and don't care. Many TV brands have way too saturated color settings by default, in a stupid attempt to fool people in the stores into thinking that this TV has better colors.

     

    I know I can't expect the same quality from a Intel integrated GPU compared with a discrete, but here the HDMI implementation is really poor, and unsatisfying. I don't do graphic work on it, but even then it is a big deal to me. If this GPU can't deliver, they shouldn't use it in a premium product with a premium price tag.

    You have gone back to 'Tech' mode again!

     

    The three most important things in customer service are Communication, Communication and er.... Communication! Certainly we need the tech people but people reading this thread are customers and being a mind reader should not be a pre-requisite of being a customer!

    --A--C-- did you try using the ADCA (Apple Display Calibrator Assistant)? It's made to change gamma and all of those kinds of display parameters.

     

    It's located in System Preferences under Displays

    Of course I did, what do you think I mean with calibrating.

    I did a full description of my issue on page 10, 2nd AC post, as I mentioned before.

    thanks for trying to help, but I do know the mac OS beyond the basics for dummies. (Mac user since OS9).

    please read the links on other threads I posted above, you'll see that the solution is not that simple... I wish it were.

    I misused the term colorsync, (i thought this utility was involved in that, but I'm wrong) thanks for pointing me the correct name of the calibration app.

    I'm more suspicious as to why Intel replaced their "official" acknowledgement of the problem with a short hollow one line comment, however time will tell whether there is a fix or not.  I don't own the Mini, and I'm holding off from buying one until there is a resolution to the problem.

     

    I don't understand why some on here are drawing a linkage between the 10.8.3 upgrade and this problem other the fact Apple's description of the upgrade includes a vague short comment about graphics drivers - we have no specific facts  about what 10.8.3 will do exactly, so making the link with this problem is a bitoif a leap...

     

    The Register and other "news" sites were simply regurgitating what what posted in the Intel forum, and lacked any further insight. 

     

    Waiting for Apple to fix it and see whether there are postings in here about it before I buy the Mini.

     

    Cheers

    No, not really. There are at least 3 ways that Apple can approach this issue. The easiest and quickest way would be to simply add a kernel extension in 10.8.3 which would avoid the bug. However this most likely wouldn't address the root of the bug, just make the symtoms go away. The most realistic way to handle something like this would be for a firmware upgrade, for EFI to fix the bug which would be a more permanent solution. I think Apple will do both, but certainly 10.8.3 first, which has already been seeded.

    Hi,

     

    Thanks for everyone's hard work.  I will throw my hat in,  got my first Mac Mini last week, using it for HTPC.  I also have the video blinking problem.  Mine is an i7 2.3 and I do have 8GB of ram from my original order.  On mine it goes for about 3-5 seconds then it comes back. 

     

    I gave up trying to read the 44 pages of post but from what I gathered, it is an issue that only Apple can resolve and we are all waiting for a new OSX update to fix the issue. 

     

    I wll also call support just to give another "unhappy" customer case on that matter.

    Correct. Intel has sent Apple the new drivers and Apple is now in the process of testing them. A fix should come either in the way of a 10.8.3 update, a firmware update, or both.

    Count me in as another person seeing this flicker problem: Mac Mini, 2.6 Ghz i7, SSD, 16 Gb, all current updates and a short, high quality HDMI cable.

     

    I see the flicker about once an hour and it lasts 3-5 seconds before re-syncing. Last night I had one that took 10-15 seconds to re-sync. I'm patiently awaiting a software fix, knowing that I received it after Oct 27 so I have until January 7 to return it.

    If you haven't done so, please at least log a call. Whatever they may be doing in private, Apple are publicly ignoring us, they need to know how many unhappy customers they have.

    I did. They handed me off to a scheduled time at the local Apple Store and closed the ticket. I haven't taken it in yet since I have no reason to believe they yet know how to fix this. Since I have until Jan 7 to return, I'll wait a bit before taking it in.
