Hi,
I do not have the choice of "Auto (Assume...)", I only have the
"Auto" choice or more specific ones. But whichever I choose, the
results seems to be the same visually. However, I do expect this ratio
to be related to the mythfrontend window size rather than the display
size, which is not what other comments seemed to imply.
I ran mythfrontend -v playback as suggested, log is in
stretched.log.gz. From the log, the lines which seem to be pertinent are :

If I use mythfrontend -v playback -nw -geometry 1920x1080+2000+0,
I get exactly the same results in the log which make no sense to me. If
I restrict the window size, then the display ratio should take into
account the window size rather than the display size no?

If I then change the display back to 5120x1440, Mythfrontend GUI stays fine: a nice window at proper size and location. But when I start a recording, it is squashed in the middle of the window.

If I change the screen size down to 3840x1080, then mythfrontend displays fine. I've tested using two different themes, both with qt and openGL as renderers.
