Good Evening, is there away in OSMC to allow it to display if the movie you are watching is in HD or not.
The media flags of our default OSMC skin show this information in the bottom left corner of video library and file views. This depends on whether you’ve set the setting ‘Extract video information from video files’ under ‘Settings/Media/Videos’: Settings/Media/Videos - Official Kodi Wiki
Other skins do have media flags information in some way or another as well.
If you want to see the details of the movie that is being played you could use the show codec info overlay. its mapped to the O as in Oscar key on a keyboard and is available as a clickable item if you pause a video with the default osmc skin if i remember correctly.
Nope, the process player info dialog is currently only available via a keyboard mapping.
