You should create a seperate profile for this.
btw with a 1050ti trying to upscale 720 to 2160 i cant use NGU sharp high it stutters like mad, i have to drop it down to low.
i also noticed that watching 4k hdr that the chroma is set at NGU sharp. is this madvr deciding this and if so how can i drop it down or to something else, i was thinking creating a profile '4K' in scaling?
also while using kodi-dsplayerx86-madvr with xonfluence skin (i hate the default one) last night (working pretty well) without touching anything it broke. it would not let me exit kodi and would just hang, even after several reboots it was the same so guess what i had to do. :-( luckily i have the settings saved as screen shots :-)
as far as i'm aware the HDR passthrough is only to send the metadata to the display to turn on HDR, its then upto the display hdr settings what profile it uses or the user has set. every time i use the 'send metadata' in the hdr settings it breaks so i leave it on auto.
it would be nice if madvr had a 'passthrough untouched' for 2160 native in 'scaling algorithms'
