I use Plex on my Nvidia Shield in a theatre room via projector set at 2:35:1 screen ratio.
Default - plex environment is ‘zoomed in’ and exceeds the screen boundaries, so I have to adjust the screen ratio 16:9 in order see menus etc, select my media and then move back to 2:35:1.
(Picture plays perfectly within frame - but subtitles will be out frame)
How can I resize the plex frame environment to 2:35:1 ratio?
