I've found the best solution is to convert the PDF pages to landscape images split over two Sony screens; I've converted a number of Cisco study books that way (rich in images and complex charts).
I've previously used
pdflrf which appears to have been removed due to GPL conflict (although I have seen it on certain p2p networks). Then there was
pdfrasterfarian which has also been removed.
Perhaps
lrftools will do what you want.
