    Secondary monitor has black screen while main is fine.


    Same problem as the 3 threads below noticed all 3 locked w/o solution: Secondary monitor has black screen while main is fine. Both monitors are detected and has its recommended resolution settings. Re-installed manufacturer drivers and forced windows to use it Mine was LG W1953; Windows kept defaulting to "Generic Non-PnP Monitor"Noticed whenever settings are changed, second monitor flashes on for a couple seconds then blacks out, so no way this is a hardware issue.Only just started using this monitor yesterday.Was working fine on boot this morning, then suddenly blacked-out a

  2. Black screen when booting to secondary monitors

    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.

    Any ideas/suggestions would be appreciated! Thanks!

  3. Black screen on boot but only on secondary monitors

    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.

    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!

    Secondary monitor has black screen while main is fine.

    Secondary monitor showing blank(black) screen after updating to 1709

    I have a dual monitor setup that was previously working prior to updating to 1709. My main monitor is an ASUS VG248QE using display port. This monitor is working fine. My secondary monitor is an old NEC LCD 1920 NX monitor using DVI cable. Both are
    plugged into my GPU NVidia Geforce GTX 660.

    Problem: My secondary monitor has a black screen while my main asus monitor is fine. The indicator light on the secondary monitor is green (indicating that signal is present). Also when going into display settings it shows that the monitor is detected and
    it has its recommended resolution settings. My computer thinks its on and working. Sometimes things get opened up on the other monitor, but I can see it bc all i see is a black/blank screen. This all occurred after updating to 1709 creaters update.

    I already reinstalled my display drivers. I even tried restoring back to 1703 but the problem persisted. I then updated back to 1709 and problem still persisted.

    Has anyone had similar problem and found solution ?
