    I think I am right in saying that TB can be daisy chained, so you would connect your monitor via MDP to DVI to the last TB device. So although you are using TB you can connect your monitor still, that is my understanding, if I am wrong I am sure I will be corrected

    I'm having this problem and am past the 14 days, but found the following.  If you purchased after 10/27/2012, you can return the Mac Mini by January 7th, 2013.  If Apple doesn't have a fix by then, I might return mine.  I like a lot about the Mac Mini, but the graphics are pretty horible even browsing and the screen blanking almost made me return the monitor I bought from Newegg.  Come on Apple.  Fix this problem before I return this machine and build a PC...

    The same problem happen for my mac mini late 2012.

    I connected from HDMI to HDMI, no connector.

     

    I hope Apple can fix this issue.

    I think this only applies to "In-Store" purchases, and not to BTO purchases.  My 2.6 Mini was BTO, and they gave me a return date of Nov.26, about two weeks after it was delivered on Nov.11.

    After three days of having no problems, I finally got a black screen for maybe half a second. Wasn't really working the graphics card or anything either, all I was doing was finding a fix for Sims 3 on the internet (Yes nothig seems to be working for me haha)

     

    I don't know what to do, because this problem happens so rarely.

    I am also experiencing the video blank out on my Mac mini i7 16gb.  My Asus monitor is hooked up from the hdmi port to the hdmi port on the Mac mini.  The display is blanking out every few days, but in my case it usually lasts longer than the 1 to 2 seconds most people are reporting.  It has been more like 15 to 30 seconds. I am not seeing any snow, just the blank screen.  I called Apple support to report the issue.  The support engineer told me that there were no known issues for what I was experiencing, even though I told him about this growing thread.  He had me do the smc reset and setup a callback a few days later to see if the problem persisted.  I did not have a blank out by the time he called back, but of course the blank out reoccurred the very next day.  I am going to call back today to reopen the case.  I do not want to exchange the unit as it seems those that have done so have the same issue with the replacement.  I may buy a thunderbolt to hdmi cable and give that a try as it seems to solve the issue for some people.  Is there anyone who is not experiencing the blank out issue when hooked up through the hdmi port on the Mac mini?

    Same issue.  Late 2012 Mac Mini 2.3 GHz i7 using HDMI to DVI with HP S2331a 1080P monitor.

    @Scott Gibby:  I'm not worried about the return policy, as that's normally designed for when you've changed your mind.

    We'd be having it replaced under warranty for another, and then another, and then another.  After a few replacements that all exhibit the problem I'd imagine you could just say "Look, they all do it.  This must be a design defect.  Either give me one that doesn't do it, or give me my money back."

    After one week, the blackouts and snow are more frequent, and when screen goes to snow, it does not come back without reboot.  So the situation seems to be worse over time.

    I will not get into an infinite loop (pun intended) on replacements because I value my time. For me, it's a lot of effort to get the mini functioning with the time to copy data over from the old machine, plus installiing Xcode, Perl, MySQL, etc. and then to migrate the deltas back to my old computer, wipe the mini's drive and reinstall the OS before returning it, and being home for pickup by the courier (Apple will not accept returns for BTO computers at the Apple Store in Canada), and being home again for delivery of the replacement.

     

    When I visited the Genius with the problem his solution was not to replace it, but to send it away for repair. One reason is because it was a BTO with the Fusion drive and they don't stock those in the Apple Store. So there's no guarantee that Apple will swap it, you may be stuck without a computer while it's gone for repair. I elected to return mine and will not repurchase until Apple announces a fix.

     

    As for a repair, I sincerely doubt an Apple tech is going to sit in front of the monitor for hours looking for a one second glitch. Unless they have another way of detecting the failure, I'm guessing it would be returned with the same problem.

     

    Until Apple understands the problem and is willing to publish a solution I think you've got two choices.

    1. Return the unit and live with your old gear until they announce a fix.
    2. Register the problem with Apple ASAP so they know the extent of the issue and you'll have a better shot at being covered under a replacement program, and hang on to the mini hoping for a fix.

     

    Since I've hung on to my 3rd party memory upgrade and Thunderbolt to DVI adapter, I sincerely hope that Apple does come up with a solution. Their silence on this issue is deafening.

    I heard Apple is collecting 200 Minis with the blank screen/snow defect for engineers to try to resolve the issue.  Being a random occurence, I think this is a good idea to reproduce the issue.  Here in the U.S., BTO's can be returned to a local store, so I'm going to use mine for a few more days in the return period, then take it down to the local Genius and return my machine as a candidate for the defect pool (if they are still collecting by then).

     

    I returned my Crucial memory upgrade, but keeping my Samsung 830 SSD, and ordered a 2011 Mini 2.5 with the Radeon GPU.  (I hear the 2011 will use 1866MHz memory.)  I'll use the 2011 as a desktop for a year, then relegate it for use as an HTPC.  No way I was going to stick with the 2012 as a HTPC with an unresolved HDMI issue that Intel hasn't fixed in five months.

     

    Apple will deny awareness of the defect until there is a fix (if it's a firmware issue). If they acknowledged it without a firmware fix, there would be a potentially massive number of returns, which would be costly. The hope is that the majority of users will not notice it since it only affects the HDMI port, and it is a random occurence. If I were keeping the 2012, I would worry about resale value if it turns out to be a hardware issue.

    Yep, the reinstall of the 10.8.2 update which temporarily fixed the HDMI screen blanking problem for me is not the solution.

    Back to having the problem after a few days.

    Apple have, as they put it 'captured' my Mac Mini for further investigation. A new one should be sent out to me once they receive it, not that they don't trust me or anything

     

    Bit of a palaver as I had to de-authorize my Adobe applications, then erase the drive and reinstall the OS, remove my 16GB upgrade and finally repack and arrange collection.

     

    I doubt if the new one will be any different but it may help Apple find a cure for this problem.

     

    For me the 10.8.2 update seemed to cure the 'snow' like interference just leaving me with the occasional blackouts. I could probably live with that as I was running extended desktop so if I made the MDP/DVI output my main screen and the HDMI/DVI the second screen which I have the floating windows on then any blackouts would be less obtrusive. Not ideal as both screens should work without any issues.

     

    I think I will live with it until a fix is found or get it swapped for the next version.

     

    I will definitely be calling Apple when the replacement starts its snow or blackouts just so it is registered.

     

    Great pity as otherwise it is a neat little machine and very nippy!

     

    Just a thought I wonder if this 'capturing' is the only way the engineers can actually get a machine to work on? I would doubt they could just get one from stock, knowing how companies work there is probably no means by which they can get a machine. Which leaves them, the engineers, having to 'capture' one and then arrange for a replacemet to be sent to the customer!

    I doubt that, since some Minis have no problem with this issue at all, I'm sure they want ones with known problems so they don't have to guess with a new one if it just doesn't have the problem, or just they don't have the problem.

     

    I bet they've pulled plenty of new ones for their testing also.
