    Me too on my HP w2408h. I've had my Mac Mini Late 2012 for 4 months, didn't have any HDMI connection problems until AFTER the 10.8.3 update. Now, my screen flickers, goes black, or has 'white fuzz' very frequently, and it is extremely frustrating.

     

    Please, we need a fix to this problem in the next update.

    I just bought the latest Macmini on Mar-2013 with the latest updated 10.8.3 Boot Rom: MM61.0106.B03 still have this screen flickering and snow screen problems. I have replace the HDMI to DVI cable (without adapter straight cable), it is better at least I can use the equitment but the problems still exist. If I connect with HDMI to HDMI the problem is gone! Had contact Apple waiting for the FIX.

    I just received my Late 2012 Mac Mini: 2.6 i7, 16 gb RAM, 1 TB Fusion drive, etc.

     

    I have this issue, and it is seriously annoying. Using a brand new Philips Gioco 27" display, and I can confirm that neither my connected cable box nor PS3 exhibit the issue, so it is DEFINITELY a Mac Mini problem.

     

    I went ahead and ordered a 6' Thunderbolt-HDMI connector to see if this fixes the issue for me.

     

    The bottom line is that this is completely unacceptable, and Apple needs to issue a legitimate fix for this ASAP.

    I'm about to take delivery of a mini in about a week. I've been reading some of these video problem threads and am starting to wonder if I should tell Apple to keep it. My concern is it's a hardware problem which is why the fix is taking so long. I was happily switching from Windows to Mac but the persistence of this issue is concerning me. Any advice?

    My macmini vidoe issues were largely fixed with the firmware update. The only issue I had since then was the crushing white lines in any open finder window. The workaround for me was to use a menubar app called "Shady".

    I've had Mac OS X 10.8.3 update installed for 1 week now and it has elimnated my issues with the crushing white lines in the finder windows...I can now see the blue background lines.

     

    For me all outstanding video issues have been resolved on my 2012 macmini ;-)

    Thanks again Apple!

    All my display issues were resolved by switching from OWC to HyperX RAM.

    Very interesting Michael, thanks!

     

    Have you contacted OWC???

    UPDATE: my memory manufacturer ID is 0x855D. ¿Is this manufacturer OWC?

    bobmepp - I've been putting up with this behavior for WAY too long awaiting a fix from Apple.  This issue is unacceptable and most disappointing as Apple appears to be dragging their feet in getting this major issue resolved.  I have been unable to use my awesome Apple 27" Cinema Dispaly monitor ever since I received the Mac Mini 2012 model.  It is truly annoying that Apple's own products don't work together even though they advertise they do.  Don't believe them.  The Thunderbolt attached Cinema Display monitor does not work with the Mac Mini 2012 Thunderbolt port.  I get by using a Gateway hdmi monitor which works fine but is not my preference.   I reported this issue to Apple 4 months ago and have received na-da from Apple on the status of the issue or any work arounds.  No wonder Apple stock is tanking.  LOL   - very unhappy customer. 

     

    Advice:  If you purchase a MAC Mini 2012, don't plan on using the Thunderbolt port for your display.

    One more thing....   I've seen a few posts about memory being the cause of this issue.  Really?   I would be surprised if memory were the cause since the issue exists no matter what kind of memory you have installed in the MAC Mini.  I specificity ordered Apple memory in hopes of avoiding any incompatibility issues.

    The issues I encountered were directly tied to memory. 

     

    You can read about it here.  My specifics are around page 35.

    I hope I stand corrected Michael.   Please repost if any of these issues return.  I'm at a loss of what to do in my case.  Return the Apple memory to Apple and ask for a refund?    I wish Apple could confirm what the issue is so we can all move forward.    Memory in your case.     -cv

    From my experience, memory is not the issue with the HDMI problem. I have used in my 2012 Mini, Apple, OWC and Kingston Memory and this problem existed in each case. Memory is an issue with the Thunderbolt Display turning off randomly and that problem appears to be caused by those who upgraded using OWC memory.

    Just to clarify -- the issue with the OWC memory also manifested with the Apple LED Cinema Display (displayport).

    2012 Mac Min - Blank Screen/Snow HDMI Losing Sync

     

    I originally wrote on this topic on November 21, 2012. That was on page 7 of a thread that's into its 21st page! At that time the problem with blank screen and snow was pretty clearly established as being a hardware problem with Intel's HD 4000 Graphics and it's HDMI output. Some users had some success getting around the problem using Thunderbolt to DVI adapters effectively bypassing the HDMI output. The hope was Apple would fix the problem with a firmware update and/or OS X updates. We've now had a firmware update and 2 OS X updates and the problems persists. From this thread you can see complaints of the same problems from units purchased as recently as this week (see OsageCowboy's March 23rd comment above as an example).

     

    And now, judging by this thread, some have been plagued with other problems as well. Frankly I'm surprised so many have been willing to put up with these problems from an Apple product and not returned them.

     

    I have a degree in electronics and worked for 15 years as a computer network engineer troubleshooting and repairing computer failures. Unfortunately this is a situation where the problem most likely lies not with Apple, but with Intel's processor. If you do a Google search you will find similar threads on the Intel communities regarding HDMI problems with the HD 4000 Graphics. Intel is well aware of the problem and no doubt it will be addressed in the next generation processor/graphics chip.

     

    Unfortunately, short of replacing the 2012 Mac Mini's logic board with a currently unavailable processor/graphics chip from Intel, it is unlikely that anyone is going to see their problem completely solved. The new 2013 Mini should be available in the 4th quarter this year, and my advice would be to hold out a few more months and hope no new threads like this one pop up again for the new Mini when it comes out. Or pick up a used 2010 or 2011 Mini.

     

    For myself, I returned my 2012 Mini in December and have been happily using my 2010 Mini. Other than having to replace the optical drive, which died after 2 years, it has never given me any problems. I ordered a replacement drive from China ($50), a couple of necessary tools from iFixit to get the job done, and also installed a new 7200 RPM Western Digital Scorpio Black 750GB hard drive. That and 8GB of Crucial RAM has really speeded things up. And like a lot of folks, I do still prefer Snow Leopard to Mountain Lion.
