How do I connect a second monitor to an all-in-one PC?

Hello, I'm trying to connect an older monitor to my all-in-one PC, but nothing really seems to be working. I have a Dell Inspiron 5490 AIO running Windows 10, and I'm trying to connect an Acer X191W monitor to it. I purchased a DVI to HDMI cable, which I thought would be ideal (the Acer has a DVI port, and the Dell has a HDMI port). Both devices are plugged in and turned on, and I plugged in the cord to both of them, but everything I try to do doesn't seem to work. I've looked though a lot of tutorials and explanations (including the one provided by Microsoft), but my settings look different. On the "Multiple displays" setting, I only have the option to connect a wireless display, but in every video or explanation I see there should be an option to extend the display which I don't have. Is there something I am doing wrong or don't have that isn't allowing me to do this?

    Hi Eb,

    I'm Amr, an independent advisor.

    If you do not see the expected options in your display settings, there may be a faulty connection or the port itself is faulty that's because your PC did not detect any monitor

    Here are a few things to check:

    1. Check the Cable

    Ensure that the DVI to HDMI cable you're using is functioning correctly. You can test this by using it to connect another device, if one is available.

    1. Check the Monitor

    Make sure the Acer monitor is working properly. You can do this by connecting it to another computer if possible.

    1. Check the HDMI Port

    Ensure that the HDMI port on your Dell Inspiron 5490 AIO is working correctly. You can test this by connecting another HDMI device to it.

    1. Update Graphics Drivers

    Your graphics drivers might need to be updated. To do this, go to the Dell website, look up your model, and download the latest graphics drivers.

    1. Check Display Settings Again

    After checking the hardware and updating drivers, go back to your display settings. Right-click on your desktop and select "Display settings". Scroll down to the "Multiple displays" section and see if the "Extend these displays" option is now available.

    1. Detect Monitor

    In the same "Display settings" menu, you should see a "Detect" button. Click on this to see if Windows can detect the second monitor.

    If you've tried all these steps and you're still having issues, it might be a good idea to contact Dell support for further assistance. They might have specific advice for your model of all-in-one PC.

    I hope this is helpful. If you require any additional assistance, don't hesitate to respond to this.
