    Not-existing 2nd monitor


    Today I changed the monitor to a new one. It's the only monitor in my setup. After plugging the new monitor in, windows is detecting two monitors instead of one. I tried everything I could find on the Internet, but nothing has worked.

    Color Display on 2nd monitor

    I am using Windows 10 on a Dell laptop with a 2nd monitor which has been working fine. For some unknown reason I have suddenly lost the full color range on the 2nd monitor. I don't know if I have changed some setting by accident or what. I have tried
    resetting the defaults but that didn't change anything on the 2nd monitor. The primary screen on the laptop continues to work fine. Any suggestions what needs to be done to restore the full color range on monitor #2?

    i have a problem to connect 2 monitors.

    Hi Ron,

    Thank you for posting your query in Microsoft Community.

    • What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
    • How are you connecting to the 2nd monitor?
    I suggest you to follow the steps from this article below:

    Windows help & learning - Microsoft Support

    [Applies to Windows 10 as well]

    Regards.

    2nd Monitor

    Hi

    Thank you for helping me. When it is on duplicated both monitors have same resolution, however, the 2nd monitor the text is unreadable and screen blurred. If on extended my default monitor is fine but the 2nd monitor goes off and my laptop screen comes on.
    I wish to have both default and second monitor displaying at the same time. As it is the 2nd monitor drop down resolution is showing 800x600 and is faded out and unable to change it.
