I am trying to use the package pgfpages with the option setbeameroption{previous slide on second screen=left} to create super wide pages to take advangate of multiple monitors. This is what I get in my PDF reader.

Since the Start icon is not aligned with the vertical box, it means that a part of the preview on the left will be shown on the projector monitor (because everything to the left of the startup icon will be shown on the projector). Some people may say that it has nothing to do with LaTeX, but a good workaround can be done with LaTeX; if I can insert an empty space between the two slides (in the vertical box position), then the two slides will be separated and any overlap will appear as white space rather than as a part of the content of the other slide. It could also be nice if the background of the empty space can be customized so that it blends with the background of the left slide (in case it was not white).

Instead of using the re-defined previous slide on second screen layout you could define a custom one and move the pages around as you please (I marked the two places to adjust values with <-...):
