win7-64 professional lock screen not blanking multiple displays
Hello,
I have been searching on the internet and not finding much other than disabling the ctrl-alt-del lock screen or changing the background for the lock screen, and neither I have an interest. I just got a new lease roll at work, I went from an HP to a Dell running 5 24-inch displays, two from the docking station, and three from two separate dual "displaylink" usb 3.0 monitor adapters. The problem I am having when I try to go to screen lock is the only screen that shows the lock screen is the primary display, the other four displays show a snapshot of whatever was open on each display (meaning they don't show the mouse moving or update). In the past they would just go to a blank (black) screen.
I did try testing the screensaver with a blank screen and when I enable that, all 5 displays show a blank black screen. I am also using the dell e-port plus 240watt model (current docking station on dells site). Two docking stations tested, same anomaly occurring on both.
I have admin rights on this laptop and am comfortable in the registry, however I am not finding much information regarding registry options and keys regarding screen lock.
thank you
