I have successfully connected two external displays to a MacBook Pro with Retina, but now I want to make it better and am asking for advice. First, this is how I did it. Connecting the TBD was easy. I connected the TB cable from the display to one of the two TB/DisplayPorts on the rMBP. Worked perfectly. Connecting the U2410 as the second external monitor was slightly more complex; but I had addressed that issue earlier when I connected the U2410 as my only external monitor (before I purchased the TBD). I had been advised to use a "Mini DisplayPort + USB to Dual-Link DVI Adapter" from Monoprice. So I used the same cable and connected it the same way. There are two connections to the rMBP: one goes to the second of the two TB/DisplayPorts and one to a USB port. Worked perfectly. Well, I had to play around with it a bit. I used a third party program to assure that the resolution on each device was set to the max for that device. Here is my problem. I want to use the TBD as the docking station it was designed to be. I want the U2410 to be connected to the back of the TBD instead of having both monitors plugged into ports on the rMBP, if this is possible. Your help is appreciated.
