They both can connect with each other with a DVI to DVI cable, I have them like that now. But it won't show up when I right-click the desktop and try to set up the monitors. I also googled DVI cables to make sure I knew what I was talking about, and I found my cable, one with white DVI heads, and it said it was intended for HP monitors, and it has a list of compatible monotors, so I suppose that's it. Can I still use the two with a generic DVI to DVI cable?
