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,
