Can you post a link to the user manual? That's much better for describing the ports and connections than a pic.
Hello, My Im trying to connect a monitor to my dell. here is how my dell looks like on the back http://www9.pcmag.com/media/images/238724-dell-inspiron-one-2305-io2305-3114msl-back.jpg
as you see i don't have a vga cable or anything to connect so will it be possible to connect another monitor to my computer. Also does my computer have hidden ports, if you look at the picture above, and look at the right side, you will see a picture of a lock and then a little opening what is that and how can i get that open? is that extra ports behind that?
