  1. Black screen on boot but only on secondary monitors

    Brand new guy with a question:

    I have a Dell Inspiron 13 connected via a Kensington SD 4000 dock to two external monitors.

    When I am in my office, the laptop is connected to the dock, and the lid is closed.

    Everything works fine, EXCEPT when I restart (or just boot up)

    On restart - the laptop boots, but the secondary monitors (both) get a black screen - I can see the mouse cursor but nothing else.

    The quick "solution" is to open the laptop lid and close it again. This immediately brings the lock screen up to my secondary monitors and then everything is perfectly normal.

    What I want to happen is no black screen, just boot up to my secondary monitors. This used to happen, but something changed and I can not figure out what.

    What I have checked:

    The display drivers are up to date. This is an Intel HD Graphics520

    The docking station driver and firmware is up to date

    The Power Saver plans are all set to DO NOTHING WHEN PLUGGED IN, and to normal power saver type settings when on battery.

    I have been on Win 10 for a while, and this problem is recent.

    All updates are current.

    Rolling back the display driver did not change anything. It is now back up to date.

    Any ideas/suggestions would be appreciated! Thanks!

  2. Windows 10 - no boot - black screen after logo

    All the answers that I have seen assume that I can windows and commands on my screen. I have a laptop and the screen remains black if I boot to the USB. If I connect a second monitor, Windows treats the second monitor as an extension of the main monitor
    but will not allow me to open windows to change display or driver settings.

    It appears that Windows does not recognize the display on my laptop, treats a non-existent monitor as the primary monitor, and the my real secondary monitor as the secondary monitor. Without visual access to a primary monitor, I can do nothing.

    Windows 10 Black screen with cursor.

    I also had only the cursor and black screen before sign-in. Once I disconnected the secondary HDMI display (to TV, primary is DVI to monitor) the DVI screen displayed correctly.
