How is the resolution of a 720p/1080p video handled on a 4K display with display mode switching on?
I'm trying to understand what exactly happens with display mode switching when it is turned on in PMP and the computer resolution is set to 4K.
I have Display Mode switching set to on and when a 720p video starts i can see the info overlay shows the refresh rate has correctly changed to 23.975, but the actual resolution is 3840x2160p. In this case is Plex stretching the 720p video to fill the 4k screen? The TV also reports that it is receiving a 4K signal whilst the media is playing, despite the source video being 720p.
