I don't think the issue here is the video system itself, but rather
software doing the rendering. I haven't browsed through any PDF reader
source code lately, but I'm guessing they probably aren't optimized
for the rendering of huge construction drawing images.
One idea (totally off the top of my head): could you try converting
one of the drawings from PDF to SVG, and perhaps other image formats,
and see how fast they render with various image display software (like
mirage <http://mirageiv.berlios.de/>). I know there is a converter
program called pdf2svg <http://www.cityinthesky.co.uk/pdf2svg.html>,
though I haven't used it yet myself.
