the video intermitently changes color or goes out
Every once in a while (I haven't noticed a pattern of when), either the video turns off or the colors get strange. I check the cables and it doesn't help. Restarting always fixes it, but there must be an easier way to deal with this. I have a Mac Mini model A1347 EMC 2840, with OSX 10.11.3
