dspdfviewer a simple viewer for latex-beamer presentations that are built
with the show notes on second screen option of latex-beamer. It will take
your PDF file, split it in a left and right half and render the two halves
individually to the screens.

In addition, your laptop screen will contain some counters and a
wall-clock, which may help you time your presentation right.
