We got a new MAC mini less than a week ago. I connected it to the HDMI port using the adapter. At first, I used a DVI-D Single link cable. The display was terrible. Although no noise or "Snow" issue, the text was fuzzy and corrupted, very low resolution images, etc. The text was the biggest issue.


What I did is that I got a DVI-D cable dual link of very high quality. I hooked it up to the DVI adpater, played around with the monitor settings. The image improved marginally.


Then, I came to this forum. I read the tip on the 25 minutes dealy in the "Engery Saver" for the display. Magically, this setting removed the fuzzy, terribly low quality text and made the screen more comfortable to look at.


At this time, the quality of the picture is at the level someone should have gotten right away without anything special done.


I am a full time engineer. What bothers me is that this issue is well known to Apple. With all of its engineering staff, they can't get this issue to be resolved, especially that the stupid "25" seconds delay solution is found by the consumers. This solution on its own should give the "engineers" a very good idea on the root cause of the problem.


I am thinking of returning it and never ever again come close to apple again, especially non-mobile devices.


If you are an engineer, you will know very well what is going on inside of apple engineering teams. (all hands on mobile, neglect and forget the desktop).


I am proud to say that I do not carry and will not carry any apple mobile device.

AppleCare is very disappointing!


I live in Shanghai (P.R.C.),there have a large Apple store,This store looks very luxurious.But there is actually can't found any monitor with Dual DVI! They do nothing on my Mac mini expect reinstall iOS10.8.3.


This issue is firmware issue.They can do nothing about it.


By the way, I also is Electronics Engineers of mobile device.

I have mid 2011 macmini worked fine with dell 2405fpw for two years, added a dell U3011 and am getting intermittent snow/static screen on wakeup from sleep with the new dell large screen. Now also a replacement dell U2412 intermittently does not wake from sleep, goes into energy save mode instead.


From above posts it would seem Apple has become a frankly dishonest organization. What a disappointment, when jobs passed so did the integrity. They will not discuss, divulge knowledge of this problem.


resetting PRAM did at least temporarily correct the "snow", have not seen it two days now .... however I do get horizontal lines and flash of rectangular areas of partil screen illumination and horizontal with the U3011 for a split second during putting to sleep.

I bought my Mac mini on Mar 2013 updated to 10.8.3 still have this SNOW screen problems. I have to scaled down the display (From Best for Display to 1600 X1200) it helps a lot, the snow screen only occurs occasionally.

Aplle is crap since Steve Job pass away! If 10.8.4 not release in May or it doesn't fix I have to return it. very annoying!
