Thanks for this. How do you add multiple options to the mpv.conf please? I’m sure it worked using the following before… (but now does not seem to with 1.2.0)
vf=vflip
keepaspect
monitoraspect=21:9
vflip does work here but the aspect ratio is still not zoomed in so I think something in Plex HTPC has disabled this function like you say. Any chance of reverting the behaviour that causes this?
I really would prefer not to have to constantly turn off and on the zoom setting or press the Z key all the time.
EDIT: I also tried this which also did not work.
monitoraspect=21:9
keepaspect
video-aspect-override=-1
