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)

Looks like I will be returning my replacement for good. Apple is aware of the issue, or at least they're saying so, and are looking toward a firmware update in the future. No timeframe. Could be days, weeks, months.


I use my macs in a production environment and this is no good, so back it goes for good, and I'm done with this mess. While I did finally find an Apple support rep who was helpful (1 out of 3) overall, customer support and service has been way below anything I've come to expect from a reputable company, let alone Apple. Really let down overall.

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.

I downgraded to a 2.5GHz mid-2011 i5 dual core, 16GB RAM, and will be putting an SSD in.


No problems and screen looks great! Once the SSD is in there, I will regain a bit of speed, not power though! I'm very disappointed by the whole thing as I was pretty excited about the quad core mini but I reported it and I'm getting my money back so done my bit to help the cause.


I would seriously suggest that people get a refund if possible to show apple that this is not good enough.


On a plus note, this one cost me £450 as oppose to £682 (with problems) so still sticking with mac osx despite this balls up as it's a superb OS and I'm sure the 2013 mini will be a vast improvement should they release one.


Just thinking about how good the 2012 mini would have been with discrete graphics makes this whole shambles even worse IMHO.


Good luck to everyone whichever path you choose, I hope things work out for the best. In the meantime, I will be keeping a keen eye on developments.


Sam.

Well said Sam, I did precisely the same, bought a refurb 2011 2.5 Mini with Radeon GPU and going about the same upgrade path. Works well so far with no black/snow screens as before. It was about half the price as the BTO 2012 2.6 ($500 vs $950), and while I would love a quad-core, it's not worth an extra $225 per core with a flawed HDMI port. Oh my, what could have been if the 2012 had the same option for a RadeonGPU? Maybe Apple will announce a "Mini-Pro" in early 2013 with a discrete GPU to correct this strategic error in product strategy. It should be easy enough since they could use the same board layout in the 2011. Good luck to all.

Intel Reports Fix Coming for Flickering on Monitors Connected to 2012 Mac Mini via HDMI


macrumo.rs/11eaHyH


Following last month's launch of new Mac mini models, a number of users in the MacRumors forums and Apple's support forums have cited issues with flickering on external monitors connected to their machines via HDMI. Connections via Thunderbolt/Mini DisplayPort are not affected.



The issue seems to be a known one related to the Intel HD 4000 graphics used in the Mac mini, and Intel has now acknowledged the issue in the Mac mini and indicated that a fix is on the way. A timeframe for a fix delivered through Apple is, however, so far unknown.

We are aware of the flickering issue, and there will be a fix provided in the future. The overall flicker issue is also being addressed here; http://communities.intel.com/thread/32932


Your OEM (Apple) will provide the driver with the fix when they are done configuring our driver (that has the fix). An ETA on this is currently unknown.

Apple has begun developer seeding of OS X 10.8.3 with an emphasis on graphics drivers, but it seems to be unclear at the present time whether the current beta version of OS X 10.8.3 contains the specific fix for this issue.

Hi all I just bought the mini display port adapter to dvi connector and it seems to be working great. Keep in mind I just got this and have not tested it for long but the images for text and speed of the output are much better. The drops were every 15 minutes to an hour on the hdmi connector. I will let you know if I see the specific blink to snow screen with this new adapter. I know it doesn't help those with the hdmi and hdmi dongle issue, but so far so good.


If you can get apple to give you one until this is fixed I recommend that. Seems to be a good work around until their firmware is addressed.


Here is the dongle that I bought from Amazon. You will need the dvi cable to go from the dongle to the monitor.

Hope this helps and good luck!
