HDMI On Mac Mini Late 2012: Problem with hardware?

Just converted from PC to Mac.

Purchased latest mac mini (Late 2012 version)


Have tried several monitors through HDMI port and each time the picture quality is poor with very bad text resolution.

Have tried HDMI to HDMI and also tried HDMI to DVI adaptor.

This is with full 1080p 27 inch samsung monitor and HP 2010i monitor.


Is there a problem with the HDMI port on this new mac mini?

The monitors I have are fine and are crystal sharp when connected to PC.


Many thanks if you can answer this

Mac mini, OS X Mountain Lion (10.8.2)

Hi. I just bought a late 2012 Mac Mini 2.3 with a Samsung 128GB SSD as the Startup Disk (not Fusion Drive) and a new Viewsonic 23" VX2370Smh LED monitor with native 1920 x 1080 resolution. The two are connected by HDMI. Certain colour details are missing, e.g. open Finder in Columns view and the vertical separators are non existent - strangely they become slightly visible when another open window is dragged across the open Finder window. The text is not sharp and, beside being extremely disappointed, usage of the setup is hard on the eyes. Horizontal separator colours are not visible on my online bank account using Safari, but are visible in my old G5 iMac. I have tried every possible combination of setting the colours in System Preferences - Displays, as well as monitor adjustments, but to no avail. I don't have cables to try HDMI to DVI etc. I intend to visit my local Apple Store and lodge a complaint. I just hope there is a downloadable fix otherwise I am stuck with a faulty product.

PS: Just borrowed a DVI-D cable from my neighbour, and used the Apple HDMI - DVI adaptor that came with the Mini. This cable arrangement fixed all the problems, and the display looks very good - colours are great, more contrast for text, column separators returned in Finder - all is well.

Hello All,


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.

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?

Hello , I have a Mac Mini Late 2012 I7 connected to an AOC 2757M which have 2 HDMI inputs and 1 VGA input.

I have tried HDMI to DVI with no succes, and I have tried Minidisplay port to HDMI with no succes. Hence , the only solution to this blurry output is buying the thunderbolt display .


Or is there any update regarding INTEL HD4000 adapter?


This is not the quality i aspected to get from Apple, I am a new Apple user. Hope there will be an update soon.

I bought a Mac Mini yesterday after my faithful Power Mac G5 suddenly died. After hooking up the Mini to my Samsung HDTV monitor (which always brought me a fine quality together with the G5), I was simply shocked by the screen quality (fuzzy text, a blueish screen with no pure whites, frightening colors of photographs, etc. etc.). I was about to throw the Mini out of the window when I luckily happened to discover this discussion.


BUT I have MacOS 10.8.4 and the problem with the HDMI connection evidently is still persisting. Everybody in this thread has been talking about upgrades which were supposed to solve the problem - but that was last year and with OS 10.8.2. I have been using Macs for 25 years now and have never encountered such a bad image on any monitor screen. Please Apple, what is happening here and what can I do?.

This is what sold me on the mini in the first place (quote from Apple site):

It’s easy to connect Mac mini to the biggest screen in the house — your HDTV — courtesy of a built-in HDMI port. All it takes is one HDMI cable to start enjoying movies and TV shows from iTunes, surfing the web, and flipping through your photo library, all in brilliant HD. There’s also a handy control that lets you adjust the output on Mac mini to fill even the biggest HDTV screen.


This has certainly NOT been the case. I am so disappointed in Apple for this. Yes, there is an HDMI to DVI adapter included with my mini, but i REALLY wanted to use HDMI...as advertised.


On top of this, when I called about the issue they acted like they had never heard of it, and that I'd have to take my mini into the apple store for a fix. Really? One google search gave me so much feedback showing folks with the same issue it was actually funny.


Fix - please!

Yes, this is a problem.

How do you then connect the DVI to the TV? I understand what you're saying about the HDMI to DVI working for you, but you're assuming I can then use DVI to feed my TV. First off, I don't have a DVI cable. Secondly, the only inputs I have for the TV are VGA or HDMI. Since the mini HDMI port is advertised as "connect to any HD television" I again say..."Yes, this is a problem."

Am I missing something?

Hello.


Mac Mini 2012 is my first MAC. Bought in december. If i had seen these post before i would never have bought the mini. I have a 24" viewsonic monitor and connected using HDMI cable. Colors are so incorrectly displayed. I tried everything that you guys said but in vain.


Really relieved when i saw Fouad post.


Hope it really cures this disease else i will put it back in the box and return to good old PC.


Thanks.
