    Laptop display question

    Confusing statement! You want to change the display on your laptop that died?

    Is that correct?

    How do you know its the display that's bad?

    Just google "how to change display on a acer 5745"

    Should get you to step by step instructions. But first make sure its the display that's bad

  3. External display with laptop and docking station

    Hi Ray,

    It is possible that there's no main display that was set to your Windows 10 devices, when you connect your laptop to the dock station. This could be one of the possible reasons that whenever you disconnect your laptop, it reverts to either of the two displays.
    To get this corrected, let's try to set a display as your main display. Here are the steps:

    • Right click or press and hold on your desktop.
    • Click on Display settings.
    • On the right side of Display, click on the display number at the top that you want to make the main display, and check the
      Make this my main display box under Multiple displays.
    • Then, you can close Settings.

    Additionally, there's an easier way to extend your monitor display so that you wouldn't need to go to the display settings every time you want to have an external display. To do that, simply press
    Windows key + P on your primary computer to see the options.

    Let us know how that turned out for you.

    Connect No Display Laptop to external display

    Laptop display does not detect itself

    Hi,

    I only have 1 computer (the laptop) and 1 external monitor. The laptop cannot detect its own screen.

    So when I follow your steps, this is what happens:

    • Go to Settings. (Done)
    • Click on System. (Done)
    • Under System, choose Display. (Done)
    • Under Multiple displays, click on Duplicate these displays and apply. (Done)
    • But then I undock my laptop and redock. Re-login, etc.
    • Only the external display turns on. The laptop does not turn on its own display. In order to get the laptop display to wake up, I need to follow steps 1-4 again. The settign "Duplicate these displays" does not seem to be retained.
