Mac Mini 2012 Snowing screen using DisplayPort -> DVI Adapter

Hello everyone,
Firstly, I apologies in advance if this has been asked already. My searches so far found people using HDMI were experiencing screen snowing issues but this was resolved through a firmware fix released by apple.
I am running the latest version of OSX and I have connected my Mac Mini to a Dell 2408WFP using the Apple Displayport/TB -> DVI adapter.
I was watching a low res movie trailer from the apple site in full screen, when all of a sudden the screen went white with snow!
This got my jimmies rustled to maximum rustlage. Turning the monitor off then back on fixed it.
Now my question, do I have a defective unit or are these still some ongoing display issues?
Many thanks,
        Mac mini, OS X Mountain Lion (10.8.3)

An update for anyone else that comes along this post.
I called Apple and they stepped me through the following
1 - Power off
2 - Remove power
3 - Hold power button for 10 seconds
4 - Connect power
5 - Hold down command option r p
6 - Power on mac
7 - Mac OS X utilities appears
8 - shut down
9 - Turn on again.
Hopefully this has solved it and it doesn't come back.
Thank you for taking the time to reply.

Hi Dono,
Though most of the "snow" issues were/are with the HDMI port, several have or had the issue with the MDP/TB port also.
A couple of cases were a defective Apple cable as I recall, but not all have been cured.
