Fuzzy Screen

We have a late 2012 Mac mini. On our HDMI Tv, the hdmi port works perfectly. If we take it to one of our monitors (works perfectly with other computers) and use the HDMI to DVI adapter, it shows a fuzzy screen with green dots. We got a new DVI cable thinking it was that, but it only helped a tiny bit. We got a Minidisplay port to DVI adapter, but it showed it a little better, but started flashing white and stopped. I ran the Mini DP VGA Update, but all it says is "The updater could not find a mini displayport to VGA adapter to update.

Mac mini, OS X Mountain Lion (10.8.3)

The Mini DisplayPort to VGA firmware update is only good if your using a VGA monitor.


I'm not sure what to make of your DVI connection problem, because I have never had any DVI connection problems with my Early iMac or 2010 Mac Mini using the HDMI to DVI or Mini DisplayPort to DVI adapters.


If you have tried resetting the > NVRAM / PRAM and adjusting the Display Preferences, then perhaps you should schedule an appointment at your local > Apple Service Provider and have the problem looked at before your 1 year warranty is up.
