With
PowerShow, you can display different
slide shows on different monitor. It can also synchronize slides on
different monitors with each other through the
Synchronous Shows feature. We
can use these features to display the same slide show on 2 different
monitors such that one monitor displays the current slide and other
monitor displays the previous slide. Assume that we have a
Left presentation that
represents the slide on the left monitor and
Right presentation
that represents the slide on the right monitor. Since we want to show 2
slides from the same presentation, we
would create a duplicate presentation and make it trail the original
presentation by a slide. The steps are as follows:
Now when you navigate Right.pptx running on monitor 2, PowerShow will
keep Left.pptx running on monitor 1 in-sync with Right.pptx. Since
Left.pptx has one slide more than Right-pptx, it will always lag Right.pptx
by 1 slide, which effectively shows the previous slide.
