Running the software locally at each display (two large, one small) is
not an option as the slides have to be advanced manually.

I've tested the set up with much shorter cables and I get full 1080
resolution. Unless I'm missing something entirely, this sounds like a
signal issue (as Mike indicated). The question then becomes whether to
buy a VGA signal booster for the longest length of cable (the one from
the laptop to the VGA port splitter) or go with VGA-->CAT5-->VGA
adapters. I don't really need much flexibility since this is installed
and no longer mobile.
Examinations are formidable even to the best prepared, for the greatest
fool may ask more than the wisest man can answer.
