Dual monitors on a Dell 790 small form factor

This question is not answered

Original display is configured VGA. Additional display is VGA and DVI. Back of the 790 is VGA and DFP. Cable connectors look to big to fit alongside one another the 790.  Suggest a video card or other means to connect the second display.

  • Post a picture of the the back of your PC so I can see what ports are available.

  • 790 sff has a vga and dp connection, you can use a dp to dvi converter or a pci-e dvi adapter ( it will use the onboard videocard)

  • If you want to go down the video card route, Dell suggests this one in the manual


    Get the 2xVGA cable option (as pictured)-
