No video output during POST or McAfee Drive Encryption PBA

[JoelRG]

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

Hello,

For POST/BIOS/UEFI the laptop vendor would need to be contacted. We provide them with the UEFI/Legacy BIOS drivers. There are plans and availability from different vendors on different platforms, but this would need to come from them.

For McAfee, if we are in touch, we can provide them with the same driver they can load in their pre-OS environment like we did when Checkpoint Software asked. Alternatively they can pick up the open source version from TianoCore.

Kind regards,
Alban
