Sky looks bad - Not a great description, I know.

[Soundchasr 19]

I'm watching a movie and the sky looks really bad.  Like the parts of the sky are clearly separated, not a smooth transition between colors.  Not sure how to describe it.  

I found this stock image on google to sort of show the effect.  Attached are my log files and other info.  Thank you for any tips!!

This should be in Roku, not Kodi.

Info    Tone Mapping would be desired, but hardware tone mapping is disabled

That's some big log. 

Try enabling HW tone mapping in Settings>Transcoding tab>Enable HDR tone mapping and see how does that compare.

I don‘t own a Roku, so this is just a wild guess.

In video details it shows profile 10, so is it possible it‘s a 10-bit file and your display can‘t show it correct ?

in top right corner it states „videorangenotsupported“.

[Soundchasr 19]

@GrimReaper  Done. I'll test that out. 

@Eigeplackter I'm going to try re-encoding in Handbrake with a Roku preset and see what that does.

Hence it's transcoding, and to get to as close colors as possible it needs to be tone mapped, which is disabled as per above snippet.

It should look something like

Something in your setup does not know it supports HDR or it is a SDR setup.

Good catch.  I wonder if that's on the Roku, in Emby or a projector issue......

Are you saying that both your Roku and projector both support HDR?

[Soundchasr 19]

I believe so.  The projector is a Sony VPL XW5000ES.

@SoundchasrHi, are you still having an issue with this?

[Soundchasr 19]

I have not noticed it recently. 

[Luke 42077]
