I've got a question: my L440 (20AS) will not boot when I connect a monitor over DisplayPort to it - it gets stuck on the ThinkPad boot logo. If I connect the monitor while Windows is running, it works fine.
The monitor in question is a Dell P2415Q, it's connected to the DisplayPort on the computer, which sits on a Basic Dock (the dock doesn't have a DP on it).
Have tried playing with various boot/power settings in the BIOS, haven't managed to find a combination that works.
Has anyone encountered/fixed this?
Thanks and kind regards,
