I'd like to connect two monitors to the computer with a dual monitor.

I only saw this as a picture, but I don't know how to connect it.

Most of them are on motherboards and graphics cards
Sometimes there's no hdmi or dvi output, but if you look at the monitor in the back of the computer, you can see if there are two
