This means you have the option of using this with one host device (ie: Bluray Player, PS3, etc.) and have the signal sent to two displays (TV, Monitor, Projector, etc.), and then simply use the selector button to switch the signal back and forth between the displays.

You can also use this as a traditional HDMI switch where you connect two host devices to it, and switch back and forth between them to display on a single TV/Monitor.

You can not use this device to watch a single source on two displays simultaneously, you must use the selector button to send the single source to whichever display you want to view at that time.

Also, the unit is small and compact which makes for easy setup and convenient portability.
