4K HEVC shows as 1080p, think I can't find any setup to fix?

[PeteGul 43]

Hi

I have an movie, that wont show in 4K. It is 4K as far as I know. And as I understand from mediainfo it is.

Using an nVidia Shield 2019 pro, latest Android universal app and lates Beta server.

Hope for feedback

Hi.  Did you confirm via your TV menus what mode it is actually in?

[PeteGul 43]

Yes, avr and tv says 1080p.

This movie (see attached file) plays as it should. And I think they are almost the same as far as I can see of MediaInfo

Do you have refresh rate switching and/or match resolution enabled in the app settings?

Both are turned on

Is 4K possible to play direct on your TV?  I assume that works.  So, is it just the playback info Display mode that does not list 4K?  Is that the problem?

Minimum 4K video is normally considered to be a height of 2160px.  Your media copy height is 2076px.  Therefore, it misses the height, normally considered to be 4K.  This could have happened if the media top and bottom black bars were removed from an original 16:9 aspect ratio which would have been 3840 x 2160.  I think that having 3840 width should be enough to qualify for 4K, but I suspect that the code looks only at the height to designate 4K, because that is the standard.  Maybe these values can be tweaked so 4K 1.85 aspect ratio without black bars doesn't get recognized as Display mode 1080P.

I have not looked at Emby's code, but typically 4K height 2160 is the minimum.  Maybe media released in 4K is 2160 with black bars for movie content with aspect ratio higher than 1.78 (16:9).  I have not checked all the blu-rays and online media standards for 4K.

Media edit metadata, you can label it 4K if you wish just manually so 4K shows up on the media page.  You can also put it in the file name after a dash.

Try turning off match resolution.
Some movies are in resolutions like for example 3840x1600 (amongst others) some TVs and AVRs don't recognize those resolutions and scale down to 1080p to be able to view them.
Turning off match resolution will keep the TV in 4K and show the movies in that instead.

Turning off the option can introduce a slight judder when watching 1080p and below videos though.
@LukeMaybe an option to automatically turn it on at specific video resolutions could be made?
