What is the model of the computer?  It may be that the video card cannot support more than one monitor.

To further Kilroy's thought, if you disconnect the monitor from the "normal spot", will the monitor connected by HDMI port now be detected and work? If it does, then that suggests that Kilroy is correct and your computer's graphics system can only drive one external monitor at a time. If that is the case and you really want to have two external monitors, then you could consider a USB graphics adapter. It would allow you to add the second monitor even if your computer's graphics system will not support. Just be aware that USB graphics adapters cannot handle graphics intensive things (i.e. gaming with a USB graphics adapter would be out except for very basic games like solitare, etc).
