    VGA Port Not Broadcasting to Second Monitor


    Machine: Lenovo - Ideacentre 300S Desktop - Intel Core i3 - 4GB Memory - 500GB Hard Drive
    OS: Windows 10
    Processor Model: Intel 4th Generation Core i3
    Graphics Card: Intel HD Graphics 4400

    Backstory: I had my computer setup and working properly with dual monitors. I needed to use my work computer with the my monitors, so I unplugged both without shutting down my desktop. When I went to plug in the monitors, I had some trouble getting them to display. I eventually got my primary monitor working via a HDMI cable. However, the VGA connected monitor was not being detected.

    Problem: I've tried to use the Windows Key + P to setup the computer for extended desktops. However the monitor is still not detecting a signal from my machine and the machine does not detect the monitor.


    • I have tried uninstalling and reinstalling the drivers on the graphics card.
    • I've tried a system restore to a period prior to the problem.
    • I tried purchasing a cable that converts the VGA port to an HDMI connection at the monitor and that didn't help.


    I'm somewhat proficient with computers and at a point where I don't know of any other solutions. I talked with somebody at Best Buy where I purchased the machine, and the suggested it could be faulty hardware. Given the number of people experiencing the same problem, I suspect that's not the case. Anybody have suggestions? Thank you very much in advance for your help.

    A semi-random suggestion:

    Clear the CMOS (also known as the Real Time Clock).

    I've had to do that when swapping graphics cards sometimes, to get the new card recognized. That suggests that there are BIOS settings that are not directly accessible to the user.

    Thank you for the suggestion on this. While I didn't need to clear the CMOS, I did boot the BIOS menu during startup, and found dual monitors was not [Enabled] in the settings. I have zero idea how this could have changed, but resetting that from [Disabled] resolved the issue.
