Mac Mini 2012 video blinking out

I just got my 2012 Mac Mini yesterday (mid range model) and have already noticed three instances where the video would blink out for about a half second, and then come right back. This happend twice already when I'm connected to a Apple 23 inch LCD monitor via the included HDMI-DVI adapter and once when I'm connected via HDMI to my Samsung LCD TV. Anyone else noticing this happening on their Mac Minis? Thanks.

Mac mini, OS X Mountain Lion (10.8.2)

I have helped over 300 clients switch to Macs in the past, never again. Apple should be ashamed of treating customers this way. I am emberassed that all I can tell my customers who have this machine is that "nothing can be done". Apple should be emberassed too. I will never recommened an Apple computer to any of my clients ever again.

That doesn't solve the problem. Any adapter in Thunderbolt still has failure issues, according to first hand experience from me and from Apple's Genuis Bar and Apple's internal bulletin. The only output that Apple says works for sure with no problems is Thunderbolt to Thunderbolt (no adapters).

Well that is not true in my case as I can run an Eizo or Formac monitor from the TB port using the DVI adapter with no issues what so ever. Both monitors also work perfectly using the HDMI port and a DVI adapter.


I can also happily profile the monitors with either port as well.


Sorry I don't quite understand that general statement concerning the TB port only working with TB connected monitors.


If it were the case I would have thought there would have been more posts here concerning this. Plenty of people posted regarding the 'blackout' problem. So I don't see people sat at home with a MacMini using the TB port with adapter suffering problems without a few more posting here?

Hemingways, from my first hand experience, HDMI is poor especially with 27 inch monitors and projectors through any hdmi method including thunder bolt to hdmi, my smaller 19inch screen looks fine using hdmi to dvi.


My solution which also works for robertfromyuma is to use a Thunderbolt DVI which works perfectly with my Epson TW 3200 projector. I also have my smaller 19inch screen running perfectly from the supplied hdmi adapter.


It's been hassle figuring this out and i was tempted to return my mac mini to apple but Thunderbolt solution works for me. Please note that I have all the latest updates and firmware installed. Try our solution again on your new mac mini if you can.

Still blinking every 15 seconds with me, regardless whether I connect direct to my tv or via my Yamaha a/v receiver. I had direct email contact with a senior AppleCare consultant, but he hasn't replied to any email - and when I call I'm told no progress by the normal AppleCare 1st line. I've had an unusable Mac mini since November and they tell me I can't get my money back anymore


What has happened to apple?

100 DAYS AND COUNTING


Yeah, more than 3 months after the release of the "late 2012 Mac Mini" and if you go back somewhere in the first 20 pages, you'll find that ALL of these fixes were discussed back then. I've got a post somewhere about the TB to DVI fix along with a link at where to buy it.


The real issue is simply this: it should work. It should just work, period.


The fact that 3 months + down the road these problems are still being discussed is ridiculous.


Yeah, "class action law suits, Consumerist, State AG's;" really terrible to consider that the Mac loyalsists who buy Minis even have to think like that. But I don't blame them a bit.


My next Mini purchase is on-hold. My faith is totally diminished with this debacle. Search "Intel HD 4000 problems" and question WHY Apple used this piece of hardware...........


My desktop purchase doesn't appear important to a company busy with iPhones and iPad variations. Sad......

I see that apple has gone to market with a product that does not perform as advertised. Somebody knows, if it is an intel problem, that can not be fixed, with a software update, or the anticapated 10.8.3 updated will fix it. Their not offical saying. My feeling is the 10.8.3 will not fix the hdmi problem because, there would have been more leaks from apple, that yes, the 10.8.3 is it.


It looks like apple is going to play hardball with the folks who paid for a product that does not perform as advertised, and will not refund the money. This is a big time blunder on apples's part.


I bought the late 2012 mac mini and I am having the washed out colors and blurry text problems. I will hope that the 10.8.3 updated fixes the problem.

TB to DVI isn't a workaround for some of us. I'm using the Mac Mini in my living room as a HTPC (runs XBMC, etc) and I use its HDMI output to send video and audio to my AV receiver for 5.1 sound. DVI does not send audio, does not support HDCP (which means I can't play protected movies etc) and my AV receiver doesn't have DVI inputs. I want to/must use the HDMI output.


As I explained in a previous post, using an EDID device inline (in my case "Dr HDMI") fixes the disappearing picture problem I had (I know someone else solved it with a Gefen Detective, which is also an EDID device). I suspect there's more than one problem, but there's certainly something wrong with the Mini's HDMI EDID handling. Dunno if that's fixable in software... when 10.8.3 comes out, if it doesn't fix it then I will be returning my Mini and wait until they fix it in a new one.

I agree with the sentiments here - I'm disappointed in Apple that they can't get simple Intel graphics to work with monitors that all other machines seem to get along with. I have a solution, not as pricey as the Thunderbolt monitor, but still up there, but I have no choice - I have a Mini for fun and a Windows 7 machine for work - two wireless keyboards/mice, one monitor - I just select a different input on the monitor.


I had all the problems we've all been crazy with across the 71 pages of this thread. Here is where I landed: an ASUS PB278Q WQHD monitor. $700 at Micro Center. 27", and it has VGA, DisplayPort, DVI, and HDMI. All cables are provided as well - nice touch by ASUS. The only con I read anywhere on the web was by c|net in that it does not have USB ports - who cares? Buy a crummy $30 hub.


All connections from the Mini work well, but the kicker is with DisplayPort (and DVI, I think)- it takes the resolution up to 2560x1440 and that's when you get the same clarity as Thunderbolt that they always have a Mini attached to when on display in the retail stores. HDMI works very nicely, but you can only drive 1080p or 1600x900 and it looks odd unless you sit back a bit. The PC with Display Port also is an amazing thing to see.


Unfortunately, after $800 for the base Mini, $80 to max out memory, $200 for a 256GB SSD to make it a speedster, and $700 for a monitor, I guess I should have just got a tricked-out iMac. Oh crap, that thing won't support another machine as a display, they take forever to ship them, and I've heard graphics complaints there too.


Good luck.
