Mac Pro / 30" Cinema Display Flickering
The studio where I work recently purchased a new Mac Pro, and since then, the 30" Cinema Display occasionally flickers. Sometimes very fast, sometimes not at all, sometimes once an hour, without any rhyme or reason. We switched out the display with another 30" and have the same problem. The tower is in a machine closet down the hall, and we use a long series of powered extenders to reach the display in the studio. This system has been in place for many years.
Here's a video of a particularly bad session:

Any thoughts? I would love to get to the bottom of this!
