W540 not showing BIOS on External display with advanced mode

I am hoping someone has found a solution to the following:-


I have a W540 in a ultradock docking station with three external monitors and I have advanced mode on dock enabled to utilise the NVIDIA graphics however on boot the bios screen is not shown on any of the external monitors.


As I have a bios password then as it does not display the prompt on the external monitors then I need to guess if it is asking for the password or not. It is a minor irritation especially if an error message or something stops the boot.


From the following article I can solve the issue by using standard video mode but I wish to use the advanced mode.


The following are my display settings in the bios:-


Boot Display Device         [Display on dock]

total graphics memory     [512MB]

Video mode on Dock        [Advanced]

Discrete GFX Perf Mode   [High Performance]

Boot Time Extension        [Disabled]   - I have tried setting this to the maximum but no joy


I have updated the firmware of the bios and the dock but to no avail - any suggestions on how to show the bios on the external monitors with advanced mode enabled?
