What a mess......doesn't Apple test things out before they put them on store shelves?
I was waiting so long for the 2012 mini's but I guess I will have to wait longer.
Hopefully they can push out an update that will solve the problem.
It would be awful if they couldn't fix it with an update.......they would have to recall all of the hardware.
I wish apple would have their own support members on this forum because most of the time users are left in the dark when a problem arises not knowing when a patch is coming.
Apple needs to get their sh#t together...........How embarrassing.
I also get the blackouts in Windows 7 so I don't think it is a driver issue.
My symptoms definitely last longer than 1-2 seconds. Usually my monitor goes straight to a static screen (though, I guess it might go blank for 1 second before hand). The static screen does not correct itself. Or rather, I haven't waited long enough for it to correct itself. The most I have waited is 1-2mins.
If I press the Power button on the back for a short time, that usually clears up the static and gives me just a black screen. If I then press the Power button 1-2 more times (always a short press), and Alt-Tab away from whatever application I was using, I can usually get the desktop back.
I'm not sure which of the steps is getting me back the desktop (i.e. Alt-Tab or mulitple Power button presses) or if it's the combination, but I do know in order to at least get the snow off the screen, the first Power button press is required.
In all honesty, this issue is likely present for less than 1% of new mini owners. It just seems more widespread since all people with issues gather in just a couple places.
I too have this problem and are using the apple hdmi to dvi adapter
Anyone here is using only hdmi to Hdmi and are having this same problem?
Groove, thanks, this is bad news... this means the fix is in Intel's hands, and not certain if firmware or hardware is the issue at this point.
It's in Apple's hands. As has been stated previously, there's a bug with the Memory Reference Code in the BIOS/EFI for Ivy Bridge. All that Apple has to do is provide a firmware upgrade to MRC 1.5 or later.
See http://communities.intel.com/message/171244, they clearly state that we should "contact [our] system or motherboard manufacturer for a system BIOS update for [our] system", and that's why everyone with this problem, no matter how occasional, should give a call to Apple to have it put on file. The more people let them know they have this issue, the earlier they're going to release the upgrade.
Nope, read a little closer. The issue IS NOT FIXED in >MRC1.5 or later, per quote below:
"I can confirm with Intel DZ77RE-75K (bios 53) and the latest Intel HD Graphics 4000 driver released this month, I am still experiencing flicker. It is rare, but it still does happen. It looks like it's a random event happening once every day or two, and I use my computer many hours a day. After going totally black, the screen recovers after a second or two. I guess whatever they did in MRC 1.5 didn't totally get rid of it."
Intel has to come with a fix first, then roll it out to Apple and other OEMs.
My bad, I had missed that. Still, it's a good thing that it's an Intel issue— they have many more customers than Apple alone. I wonder if this happens on the Ivy Bridge MacBook Pros too, and if it will affect the new iMacs.
I have my Mini for 2 weeks and never noticed this issue (with TB to VGA adapter). Yesterday, I found this topic, so I switched to the HDMI to DVI adapter aaaaaand... it's just happened. black screen for 2-3 seconds. now I'm pissed off. I still have 1 day to send back this device to Apple...
I posted on another users thread regarding displays and the issues I have had with the new Mini's. Apparently I am not alone as Apple is aware and I have a case number now. For those of you with the new mini's, the symptoms manifest for me with the following:
System will randomly go to a black screen for 1-3 seconds.
Sometimes it will turn the display to snow (like it switches the monitor to a resolution it can't handle)
Happens about 4-6 times per day.
I have only dragged a HDMI cable out of the box for this. (I've been using my existing miniDP->DVI without issue).
It didn't take long for mr Black Screen and his pal Static'o'leary to show their faces. I booted the HDMI cable back into its box (also the display quality is bloody awful compared to the DVI cable on the same screen).
Next I tried the apple HDMI->DVI adaptor as supplied with my 2012 mini. this too allowed mr Black Screen and Static in. switched the DVI plug back into the miniDP->HDMI and all is once again well (no issues).
So my testing in my case shows the HDMI output to be at fault (with or without using a HDMI cable pure or a HDMI->DVI adaptor). My screen, DVI cable and miniDP port all appear to me non-faulty.
now I guess the wait begins for apple to a)admit it and b)solve it - hopefully before January as thats when I plan to get a second screen to match my current one and then of course I shall need the use of that HDMI->DVI....
