I have two Thunderbolt Displays and a 2011 15" Macbook Pro w/ Thunderbolt. When the two displays are plugged in, only one is recognized. I tried switching around cables, installed software updates, nothing has worked. Suggestions?
Got a tip for us?

Second Thunderbolt Display not working?

Figured it out. Not enough power for both of them. I unplugged an iMac next to them, and then it worked fine. As soon as I plugged the iMac back in and turned it, the monitor stopped working again.
