Mac Mini display problems

[davidbaird]

Using my late 2012 Mac Mini with Yosemite installed earlier today and the screen started flickering.

Here's a video - https://dl.dropboxusercontent.com/u/133785/IMG_0698-1.mov

It's hooked up to a Thunderbolt display.

Anyone know what could be causing this?

While not that bad I do get the occasional flicker and I've read more than a few post on this and the apple community board - have you tried a new cable?

I upgraded my mini-dp to dp cable and it helped - definitely should not be that bad.

What monitor is that?

Thanks - it's the Apple Thunderbolt monitor so connects via a built in Thunderbolt cable.

I'm going to give the Mac Mini a good clean and try running the screen via a different Thunderbolt cable to the port on the back of the monitor.
