No video output during POST or McAfee Drive Encryption PBA

We are using multiple (>100) Dell D6000 DisplayLink docks. We are having an issue where we are not getting any display on external monitors during POST or McAfee Drive Encryption Pre-Boot Authentication. The external monitors don't display anytihng until partially booted into Windows. We're using the latest Dell firmware for the D6000 and I've tested the latest DisplayLink driver from the DisplayLink website - no change. Also using the latest BIOS for our Latitude laptops.

Is it possible to get external monitors working on these docks during POST and/or before the OS loads?

Thanks,
Joel
