for anyone who still needs to fix slide resolution and either has only
the PDF or produces them with a tool that doesn't take "just scale
everything up 10 times" easily (looking at you, LaTeX beamer), the
pdfjam tool (shipped with texlive[1]) provies an easy way to do this:

$ pdfjam --suffix upscaled --papersize "{1600mm,900mm}" slides.pdf
