I have an older (2014 I think) HP pavilion 23 all in one and I’m trying to connect a second monitor. The monitor only mirrors the all in one. The all in one doesn’t even find the second monitor, I’ve installed drivers, updated the video card ( Amd E2- 3800 W/Radeon HD). I’m at a total loss of how to get the second monitor to be an extension of my AIO.
I am using VGA to USB adapter - I installed the drivers for it and did everything like I was supposed to. It’s supposed to automatically recognize it. I have also installed a 3rd party software to try and get that monitor recognized. (Auto Multiple Monitor thing)
please help!

What is your HP pavilion 23 all in one ?
HP has many different AIO machines
- Some have no HDMI port at all,
- Some have HDMI in only,
- Some have HDMI out only,
- Some have both.
You need HDMI out port to connect to an external monitor. Please use the following way to find out what is your machine:

It does not have any HDMI port. You need USB adapter which is Displaylink Certified to be able to connect to an external monitor. There are some on the following list
