I have a Mac Pro (late 2013) and an Apple Thunderbolt 27-inch monitor, running 10.10.4, and as far as I can tell, the firmware is all up to date. Starting a few months ago my monitor will suddenly go black for a fraction of a second at random moments. It happens several times per hour, typically. Suggestions? Thanks.

Have you tried a new cable from the Mac Pro to the Thunderbolt monitor? Also, is your Thunderbolt monitor still under warranty or extended Apple care?

Is the connection good with the computer? It's very possible that the issue here is simply a loose cable.
Indeed, switching the cabe to one of the other Thunderbolt ports fixed the problem! I haven't convinced myself yet if one of the ports is bad or if the connection was just flaky, but the intermittent screen blanking is gone. THANK YOU.
