  1. Laptop Screen Dimming when I Click on External Monitor


    Hello,This may be as simple as me just not knowing what setting to change, but I couldn't find a solution anywhere else. I recently updated my drivers on my HP Envy x360 laptop, and after restarting, a feature seems to have been turned on that dims whatever window is open on my laptop. I am using 2 external monitors connected to a port and neither of the external monitors dim when I click away from them, only my laptop screen dims when I use one of the external monitors. However, it is not the screen dimming, because the taskbar across the bottom does not dim at all, only whatever window is op

    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:

    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)?
     
  4. Laptop Screen Dimming when I Click on External Monitor

    Laptop suddenly stopped recognizing the external monitor

    Hi,

    Thank you for posting your query in Microsoft Community.

    To assist you better, I would like to ask if the laptop is unable to recognize only the external monitor or other external devices also.

    I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

    • Click on the Start button, and type “Troubleshooting” on the search bar.
    • Click on “Hardware and Devices”.
    • A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.

    Hope the information is helpful. Keep us posted on the status for further assistance.
