    [nVidia] - Second Display Not Working? - DVI Monitor & Second HDMI TV


    Running current Windows 10 Home 64Bit version 21H1on a fairly new Dell desktop computer.
    Have an nVidia GeForce GTX 1650 Super graphic card with newest non-beta drivers.

    I have a monitor plugged into the DVI port on the nVidia graphic card.
    I recently plugged a second television into the HDMI port on the nVidia graphic card.

    When both displays are plugged in only the DVI monitor is working?
    I used nVidia control panel to setup a clone of DVI monitor onto the HDMI television.
    When the television input is switched to the HDMI the computer is connected to it says no input found?
    When I go back to the nVidia control panel, the television is listed, but it is not selectable and grayed out?

    The weird thing is that sometimes it works - maybe 1 out of 50 tries?
    Anyone know how to troubleshoot this issue?
    If you need any more info then just ask.
    Hope to have this working soon, thank you!

    hmm.. sounds like that particular TV is not supported...
    I would suggest only connecting PC monitors to your PC be it connected via DVI, HDMI, or DisplayPort...

    I thought that there might be a requirement that one of the monitors use DisplayPort, but a little online searching found a claim of running two monitors where one is DVI and the other HDMI.

    Can you run the TV as a single monitor? (Disconnect the DVI monitor.) Not sure how much that'd help, but I'd try that.

    I have an idea:

    I will try Display Port instead of DVI.
    The DVI monitor is old so I will use a Display Port(male) to DVI(female) adapter.
