    connection problems External Monitor for laptop

    If you're trying to use a wired external monitor is it connected to the laptop's HDMI output connector or the mini DisplayPort connector?

    If you're using a wired external monitor and don't see any output, right-click on an empty spot on the Desktop and select Screen Resolution -> Detect

    In addition, you may need to press the F7 key and select the mode in which the display will function. There are 4 modes:

    • Disconnect (or Computer only): display only on the laptop's screen
    • Duplicate: the same display on the laptop's screen and the external monitor
    • Extend: extends the output so that you can drag things from one screen to the other
    • Projector only (or Second Screen Only): displays only on the external monitor

    Or are you trying to use wireless (Wi-Di or Miracast)?

    Laptop screen will only work once it has been connected to an external monitor, even if that monitor is switched off

    Having an issue whereby I cannot see or use the Laptop screen without first plugging it into an external monitor.


    • Upon Windows startup unconnected to any external monitor

      • DELL opening logo can be seen on Laptop screen

      • Screen goes black with backlight

      • Mouse pointer can be seen onscreen if moved to the right, as though a second monitor is connected on the left hand side.

      • Attempting to press enter and type in password in the correct order as though the screen was functional does not do anything

    • Upon connecting to an external monitor (even if switched off)

      • Laptop screen will suddenly appear, all functionality restored

    • Upon disconnecting again from external monitor

      • Laptop screen remains visible and functional

      • Lock screen /unlock screen no problem

    • Upon shutting and opening the laptop lid

      • Screen black with backlight, same results as windows startup, mouse pointer can be seen and moved as though a second screen is connected on the left

      • No functionality until reconnected, even for a second, with an external monitor.

    Troubleshooting:


    • Restarting multiple times, checking multiple display screen is not activated:

    Laptop External Monitor Problem

    Thank you once again, I will explain:

    • Today 10th November 2016 - After monitor eventually successfully connects to my HP laptop, in my absence when the laptop/monitor powers off, I get NO re-connection problems during the day
    • Tomorrow 11th November 2016 - After laptop and monitor has been restarted following, shut-down, power offs(laptop + monitor) I will be stuck once again with exactly the same problem

    In my display settings each morning, my HP laptop shows it is connected to my external monitor, however there is no display on the external monitor for a vast amount of time, just randomly suddenly appears.?
