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! greetings, el On 2020-06-17 23:31 , Rich Shepard wrote: [...] > 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.
