Nvidia Shield no longer shows Dolby vision just HDR it worked before though

I can’t figure out did I do something is there a setting? Everything worked yesterday now, only HDR is triggered. I reset the Shield no go same problem, I tried messing with the plex settings. They seem to have no effect.

Any help would be very much appreciated.

This is on the Shield help pages, but even then I didn’t think the Shield had native hardware support for Dolby Vision. I suppose it has software support going by the screenshot below.

I am sad to say I have tried that multiple times. No change, the option is available I turn it on but no change. It acknowledges the TV can do it but then when the DV title is played it plays HDR instead.

I’ve only had this issues since i updated to 8.2.1 the following media type isn’t being picked up as dolby vision:

Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible

Yes it’s still on. Some files still trigger DV. but some files that were working before the update have stopped.

I agree with andcbii. I’ve found that Plex is still a bit unreliable at playing DV from a MakeMKV rip(1.15.3), always after a reboot of the Shield(I have it set to 59.95 HDR and DV ready). After a reboot, none of my DV movies initially trigger DV or even HD at first(I have both 4K and regular blurays ripped for other TV’s). I have to go through a routine to get Plex to start recognizing DV.

After a reboot, when just pressing play the first time on any DV movie, it looks like it is trying to play the 4K DV, version but fails and I get a generic greyish background for a couple seconds, then black, then another generic greyish background again(I’m assuming it’s failing the 4K test too), then it starts playing the regular Bluray version.

If I stop it and then force it to play the 4k specific version, it will then only give me the greyish screen once and proceed to play the 4K version but not in DV. If I THEN stop again and go back and hit the normal Play button again, everything then works mostly ok, from then on, until another reboot. It will play not only the 4K version but also trigger DV on MOST of my DV content. This pattern is pretty constant after a reboot of the Shield.

I have tried…
1917
A Quiet Place
The Matrix
The Matrix Reloaded
The Matrix Revolutions
Atomic Blonde
John Wick 3
Ready Player One

These have all been ripped with MakeMKV 1.15.3. The only movie that continues to be stubborn(after I get the Shield to start playing DV consistently) is the original Matrix movie. It is still picky in that it won’t always start in DV and I have to restart it until it does.

The main issue though is after a reboot, nothing works until I force it using the routine above.

As a note, I have a Sony X950H TV and using the old method of creating a single layer .ts version always worked 100% of the time with Plex.
