One of My 2 Thunderbolt Displays Keeps Winking Out

I have a mac pro 6.1 with 2 Thunderbolt displays-one shuts down after a period of inactivity, while the other remains on. I have to restart the computer to get both displays back working. What's up? is this a "settings" thing, or is something wrong with one of the displays?

Mac Pro, Mac OS X (10.7.4), 2 x 2.66 GHz Dual-Core Intel Xeon

Hi hiltcreative,

If one of your Thunderbolt displays is unresponsive after a period of inactivity, take a look at the resource below which is specific to the 27-inch model.
