PowerShow is a multi-monitor software add-in for PowerPoint that allows users to view a slide show on one monitor while continuing to work on something else on another monitor. It supports Wide Format, viewing presentations and formatted notes on different monitors, and viewing shows on multiple panels arranged in a matrix layout. It can also run a ticker slide show simultaneously with the main one, and users can view videos on a monitor while controlling.
