I was having an issue with the display as well until I ran configuration. Go into system prefs/display/color and caliberate. It adjusted to my screen a lot better. When I first turned on the mac mini it didnt look "crystal clear" as it does now. Could help.....

No the calibrations don't work. I am convinced it is something with the HDMI port.

Read the "blinking screen" threads in the forum... problem with Intel HD4000 and HDMI.

OK. So I have now tried LG 27 Inch E2742 Monitor as follows:
1) Mini display to DVI-D : Picture good with decent text resolution
2) HDMI-HDMI: Picture poor with poor colour and text resolution. This is not a calibration issue.
The samsung monitor 27 inch series 3 also has poor picture and colour and text resolution with HDMI-HDMI. Again this is not a calibration issue. It does not have a DVI-D input to test the minidisplay port.
So it seems the HDMI port is not working properly but the minidisplay one is ok as I suspected.
From reading the other threads it seems this is a common problem including those people that have taken their minis back for an exchange and experienced same problem.
Is there likely to be a software update to resolve this?

I just purchased my 2012 mac mini andi'm suffering from the same problem. I connected my mac minii via HDMI to my Samsung 46" ES8000 and I have to say the picture and text quality is quite disappointing. I'm comparing this to my 2007 mac min ithat was connected via DVI and I have to say there is absolutely no comparison. No matter how much i try to calibrate it the colors are really over saturated, there is no good color depth, and the text quality is poor. I hope there is a way to fix it as I'm really relying on HDMI to connect as the new samsung dislplays don't have a DVI input.

Yes I had to change to LG monitor which has DVI and HDMI whereas Samsung only has HDMI.
I phoned apple to log this. I suggest you phone and log it as well and hopefully soon there will be a fix.

I was about to buy a Mac Mini 2012 with the 2.6GHz upgrade and 1TB Fusion drive. Fortunately all these forum postings have made me hold off! I was planning on using both the T-Bolt and HMDI display out ports for two identical monitors. However it seems we have two issues, this blinking black/snow on the HDMI out and poor video quality on the HDMI out anyway (see other fora). It's a nightmare, but very little is mentioned in the tech press, bar the ARS Technica review (which couldn't replicate the issue) and Lockergnome.
Is there ANYONE out there with a 2012 Mac Mini that works perfectly on the HDMI out?
Is there ANYONE out there running two identical monitors on HDMI and T-Bolt without any comparative display differences?

Me and many others have no issues with HDMI connection.

I have the 2.3ghz Core i7 version and HDMI works fine EXCEPT with the HP 2311x LED monitor the resolution was restricted to 1080p and the text was fuzzy. Using the HDMI - DVI cable that comes with the Mini corrects the issue and allows you to set the digital resolution to 1920 x 1080 @ 60 Hz and the display is spectacular.
It's quite possible the HDMI interface on the display was the issue, I didn't bother to troubleshoot since it's working great on DVI.
Remember, if you are using HDMI - DVI it's the same port but conversion to DVI is done on the adapter vs. HDMI - HDMI which relies on the conversion within the monitor. IT's a monitor issue, not a Mac Mini issue IMHO. I noticed the same thing with my Windows video, DVI was always better.

Hi Everyone, Does anyone knows what could be happening? , Is this will be fixed with a driver/firmware upgrade or could be a Hardware issue with HDMI, also I hope OS 10.8.2 could be available this week. =''(

model identification: Macmini5,1 + Lion, bought in europe 2012
1) Macmini works perfectly connected via HDMI to a Samsung Tv 40" with a cable which is not the adapter
given by Apple (apple HDMI adapter)
2) Macmini has problems when connecting to an Apple monitor LED Cinema Display with the apple HDMI adapter
In my case the problem was the Apple HDMI adapter cable, I changed that and Macmini works perfectly with
