We are currently rolling out EEPC 7.01 and have a number of Dell Precision m3800 systems that utilize a USB display adaptopr for systems using a docking station. The pre-boot display is not visible when the system is docked and the user is required to undock, open laptop screen and authenticate at Pre-boot. I have enabled "Always enable pre-boot USB support" and users are still not getting the monitors to display pre-boot login when docked.
Are there any steps we can take to allow users to see the pre-boot auth screen when using this docking station configuration?
If the UEFI or BIOS does not support this USB display, then it won't be possible to support it in the EEPC pre-boot.
