Hi,

I have a  DELL Latitude Laptop connected to a docking station.  I have two external monitors (DELL) connected to that docking station (DVI).  The laptop's monitor is closed because I only want video input on my external monitors.

Using that configuration, I don't have any input until Windows login screen.  I can't see bios post or anything that happens before Windows login screen.  

I checked for any setting in the bios without luck.

Any help would be appreciate.

Thanks.
