Mini Displayport Adapter

[Planemaker]

From what I read to connect an external monitor to my dock I need and active mini displayport adapter? Correct?

Any recommendations on which one to get?

That is correct. Without the "Active" adapters, the monitors won't resume from sleep/hibernation. My Surface Dock is connected to (3) external monitors. I have (2) connected with active DVI adapters and one is connected via a USB to DVI adapters. Up until Sunday's update I was able to use (3) external monitors and the Surface monitor at the same time. Now I can only get (3) at a time to work.
