    2nd monitor not displaying?


    Windows 10 home fully up to date, 32 gig of ram 6 cores

    Wasn't sure where to post this problem as it could be caused by a number of things?

    Anyway, I use a dual monitor display connected to a Nvidia Geforce GTX 1650 super graphics card, the card is only 2 months old and has worked perfectly until I started my PC desktop yesterday morning. The PC booted up as normal, but only monitor 2 showed the main desktop, the other monitor would not switch on, yet I could move the mouse cursor onto that monitor even though all I could see on that monitor was a black screen.
    This is where the fun starts:- I fiddled around with the hdmi cables, even trying a new one with no luck, then about an hour later the missing display suddenly came on again and continued working properly for the rest of the day?
    Then today I started my PC and the monitor that didn't work yesterday was now working, but the monitor that was working yesterday was now a black screen?
    So I know it is not the monitors that are at fault, and in Display Settings both monitors are shown and said to be working correctly? I have restarted the PC several times with no change, only one monitor displays.

    I really don't know where to start trouble shooting this problem, I've checked the drivers and run the trouble shooter in Display Settings with no change?

    Any advice and help welcomed?

    - - - Updated - - -

    Just swapped the power supply cables around and both monitors are now working? Don't know why this should affect either monitor, but it has!
    Will wait until tomorrow before I start up again to see if they are both still working. Will let you know the outcome then.

    :)

  2. 2nd display monitor

    Hello, my name is Brad, I'm an Independent Advisor and I wanted to add to my colleagues' efforts.

    Below is a link to a walk-through that will show you each step to enabling the 2nd monitor.

    On the walkthrough, if you click the button that says "Open Display Settings" and says "Ok" to the prompt, the Display Control panel will be opened on your computer for you. Not worry, this page is hosted by a different part of Microsoft so it's perfectly safe.

    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?

    Hi Billy,

    This is Wil, one of the independent advisor and an expert with Windows 10.

    I understand your concern with Multiple displays.

    To get your PC to recognize multiple monitors:

    1. Verify that your cables are connected properly to the new monitors.

    2. Select how you want the desktop to display. You can press the Windows logo key + P and select an option, or use the following steps if you need more settings options.

    3. Right-click anywhere on your desktop and select Display settings to open the Display page. Your PC should automatically detect your monitors and show your desktop. If you don't see the monitors, select Detect.

    4. Scroll down to Multiple displays, then select an option from the drop-down list to determine how your desktop will display across your screens. For the largest work area, select Extend desktop.

    5. Select Keep changes.

    6. Scroll up to Resolution and select an option. We suggest that you use the recommended resolution settings.

    7. Select Keep changes.

    I hope my suggestions help you. If you need further assistance please do reply back and I will respond as quickly as possible. Have a nice day.
