Help: My Avid Client Monitor Is No Longer Working

I often switch between Avid Media Composer and either After Effects or Premiere Pro when editing. My system is equipped with a Blackmagic video card that pushes a signal out to my client monitor. When I leave Avid and switch over to After Effects or Premiere Pro, my client monitor will change over as well, displaying what is in the program monitor of either After Effects or Premiere. However, more often than not, when I switch back to Avid, my client monitor is still blank.

When I first started using Avid, I didn't know what was going on. I tried closing out of Premiere or After Effects. I tried closing and then re-opening my Avid sequences bin. I tried closing and restarting Avid. I couldn't seem to find the solution, until another Avid user told me about this little toggle switch, located at the top of the sequence window. 

Here's an example of an Avid sequence I'm currenlty working on: 

Notice the long row of buttons running along the top of the timeline window. Then, in the middle, is a long black bar. To the right of the black bar are three additional buttons. See below for a closer look: 

One button looks like three stacked rectangles. The second contains a circle. The third contains two gear symbols. If your client monitor isn't working, look at this button. You will probably see a red circle around the gear icons and a red line crossing through the gears. If this is the case, simply click the button and your client monitor will once again receive a signal from Avid.
