Been looking at picking up a Mac Mini but have read some reports of screens going black for a few seconds before returning to normal. Now I know that people with problems are much more likely to complain than happy users reporting they have no problems...but I just want to ask before I drop a good chunk of $ on it. This is specifically for 2014 Mac Mini's. Has the screen ever gone blank/black for a few seconds and then returned? If so, how often? What monitor? What type of cable is being used? (DP, HDMI-DVI etc) Thanks everyone, I sincerely appreciate your time.
