When using Symantec Drive Encryption (formerly known as PGP Whole Disk Encryption), during boot, the external monitor connected via DVI-D or using another digital cable does not activate to show the Symantec Disk Encryption (formerly known as PGP) BootGuard log on screen.
Incompatible BIOS settings with Symantec Drive Encryption (formerly known as PGP WDE) Pre-boot Authentication screen (BootGuard). This is due to hardware limitations regarding the Nvidia Optimus Technology from the hardware vendor(s).
There are currently no plans to address this issue by way of a hotfix or Maintenance Pack in the current versions of the software or in a future release at the present time. This is due to this being a hardware limitation.
Known workarounds:
Note: Pulling out the VGA cable while it was displaying to an external monitor and leaving the DVI cable plugged in does not result in sending the video the DVI. You will have to reboot to re-route the signal correctly. The information in this article is subject to change as hardware vendors may introduce new changes to the specifications in the future. At the time of writing this article the reason this does not work is due to hardware limitations with the Nvidia Optimus Technology in its current implimentation from the vendor.
