  1. second screen wont detect


    Hi.

    Just trying to set up a second screen for my desktop pc.

    I have one VGA port in the PC, so bought a vga splitter. Plugged both in, main monitor works as it should, second monitor mirrors the main monitor and has the wrong resolution. Ive rebooted the PC, ive updated my display adapter drivers to newest version, ive been to my Graphics Properties (left click desktop, graphics properties) and only one monitor is showing. Ive tried Windows key+P and all of the different options in there make no difference whatsoever. When i go into the display settings and click detect, it says 'didnt detect another display'.

    Am i doing something wrong? Please help.

    Thanks,

    :)

  2. Project Second screen constantly appearing.

    Hi Norga,

    Thank you for using Windows 10.

    Let us know some more information so that we can diagnose and troubleshoot the issue in a better way:

    • what is the exact issue that you want us to help with? Do you want to get help in projecting a second screen or to remove the popup?
    • As you've said " I tried unsuccessfully to project a screen", do you wish to project a second screen currently?
    • What happened exactly when you tried to project a second screen? Did you receive any error message or any error code?
    The popup comes as the system might not be able to detect the monitors. I suggest you to update the Display drivers, it may force the system to detect the available monitors. Here is the steps:

    • Press “Windows + X” and select Device manger.
    • Locate the driver and expand the driver icon.
    • Right click on the driver icon and click on Update.

    Reply with the information and we'll be happy to assist you.

  3. Laptop display does not detect itself

    Hi,

    In regards to your concern, since the second screen can't detect the display settings of your other laptop, we suggest that you perform the steps below and see if it helps:

    • Go to Settings.
    • Click on System.
    • Under System, choose Display.
    • Under Multiple displays, click on Duplicate these displays and apply.
    Let us know the details so we could further help.
