My pdf reader (evince) supports dual display, i.e pages are not shown consecutively but 2 in a row:
slide 1 | slide 2
slide 3 | slide 4
Use case: I'm viewing a PDF with a slide on each page and the best fit would be to watch 3x2 pages (slides) at once.
slide 1 | slide 2 | slide 3
slide 4 | slide 5 | slide 6
Is there a reader, preferably for linux, that supports this?
Long story short:
yes there is: qpdfview
for windows @Timmy recommends Foxit
depending on your nerves printing and rotating your screen is an option, thanks again to @Timmy for his efforts.
@Timmy suggests printing to file with 6 original pages per new page.
I link to this as a sample document since it's the first google result for 'latex beamer example'. In case the link dies, any slide with ratio 4:3 will do.
With evince, I tried:
The slides overlap and there's plenty of empty space(select image to see better)
