Hi jackskellington, and welcome to our community!


The question is a bit unclear. But I'll answer according to my understaning and you can correct me if I'm wrong.


Your computer has only a single video output for a monitor (a blue VGA connector), so if you want to be able to have a 2nd monitor connected to it you'll need some kind of graphics adapter. Either an internal dedicdted graphics (which might be cheaper but could be compicated to install and setup) card or an exteranal USB graphics adapter.


I'd say that something like the Plugable USB 3.0 to HDMI\DVI\VGA Video Graphics Adapter should be a good option.
