Re: Beamer presentation PDF resolution [RESOLVED]
Thank you also very much for this RTFM!!!
After 10 years of being irritated that the Beamer presentations of mine
leave a black frame in full screen, I now finally found that
aspectratio=1610 removes it.
Tested it with Skim, Acrobat and Preview (and on Zoom) and looks great.
Need to look at it with a beamer, but nowadays we do our CPD with Zoom
so I don't have (need) ready access to a beamer anymore.
On my iPad Mini 5 with sidecar the standard (43?) looks best so I will
need to try different ratios on the beamer when we go back to F2F.
Fortunately with Makefile or a for loop it's rather easy to produce a
PDF in each supported aspect ration and then try every one on the
beamer and use the one that looks best.
This is great stuff!

Rich,
glad to know it worked. I've found it a while ago as a stackexchange
question (here:
https://tex.stackexchange.com/questions/14336/latex-beamer-presentation-package-169-aspect-ratio
), but it seems is in the beamer user guide too:
http://tug.ctan.org/macros/latex/contrib/beamer/doc/beameruserguide.pdf
in paragraph 8.3
In LyX i think there is lyx/beamer guide, not the complete beamer
manual.
Regards,
G.

It should go in Class Options -> Custom
Without quote, btw.
In the source view it should be like this:
\documentclass[italian,aspectratio=169]{beamer}

Giovanni,
That explains it.
I'm moving my business marketing/prospecting to use video tutorials on a
YouTube business channel so I need to upload them as 1920x1080 or 1280x720
resolution files.
The beamer output is now in 16:9 aspect ratio, and the softwar I use to
display the PDF for the recorded video tutorials ('impressive') is scaled to
open in a 860x540 dpi window, half the final resolution. I use ffmpeg to
scale it up and it all works fine.
Thanks for adding to my LyX/LaTeX/Beamer knowledge,
Best regards,
Rich

Giovanni,
I must have mis-typed something the first time I tried it as a class option
(of course no quotes) because this time it worked.
I searched the Beamer manual (in LyX) for 'aspectratio' and it found
nothing.
Thanks for your help.
Regards,
Rich

How can I set the PDF output to a 16:9 ratio using either 1920x1080 or 1280x720 resolution? I found the tool, now I need to learn the proper command line. Turns out that ffmpeg, the commplete video/audio toolbox can change ratios and, I presume, resolutions. So, off I go to figure out ffmpeg.
