Hello,
I just set up my Magnetar 800 and I love it. The one issue I have is that it is selecting HDR10+ over Dolby Vision on 4K UHD discs. On discs that have only HDR10 and Dolby Vision it selects Dolby Vision. In settings I have HDR and Dolby Vision set to Auto. Is there a way to force it to select Dolby Vision on discs that have HDR10+?
Regards,
Dan Reich
Can you provide a disc title that has both HDR10+ AND DOLBYVISION? Also, your TV make and model?
Thanks
1917 4K, Stanley Kubrick 3-film 4K Collection, Wall•E 4K (Criterion) are the ones I have. Admittedly HDR10+ is not a widely used format and I did not buy these for the HDR10+ versions. It's frustrating for me not being able to access my format of choice, Dolby Vision, on these films.
My TV is a Hisense 75U8N. It supports HDR10, HDR10+ and Dolby Vision.
The Magnetar 800 replaced a Sony UDP 800Xm2. It did not support HDR10+, also I had to manually turn Dolby Vision on and off otherwise it "upscaled" everything to Dolby Vision, which to me is not desirable.
The player priority when both are set to auto is: Dolby Vision>HDR10+>HDR10>SDR.
With that, you should be seeing Dolbyvision if it is on the disc. We will see if we can replicate your issue as you describe it.
What is the result if you set HDR at SDR or HDR (not auto), does Dolbyvision then prevail?
Must be a defect with the 1917 disc. The other discs mentioned play Dolby Vision with no problem. I should've checked all of the discs before I started the topic. Sorry. Thanks for your help.
I hate to re-open this topic but the issue is not resolved. I bought another copy of 1917 thinking that if the first disc was defective, a new copy might solve the problem. It did not. Magnetar 800 is still selecting HDR10+ over Dolby Vision. I'm having the same issue with the new 85th Anniversary disc of The Wizard Of Oz, Criterion Wall•E 4K, and all of the discs in the Stanley Kubrick 3-film 4K collection.
We have evaluated this issue at length. The movies are not in Dolbyvision , they are in HDR10+. Other content on the disc is in Dolbyvision which is why the disc bears both logos.
We've tested many discs that represent both formats on the disc and have found in every case, this is the resolve.
We have not seen a single disc which has both Dolbyvision and HDR10+ for the movie itself.
You will find in many cases the studio logo card pre movie roll is in Dolbyvision and the movie is in HDR10+.
We are unaware of a disc that can accommodate both formats
Thanks
Ok. I wish they made that clearer on the disc box. My workaround is to tweak the settings on HDR10+ to match Dolby Vision IQ more.
We agree wholeheartedly. We had another customer raise the issue and he submitted this video, which you can see is both formats as both logos appear on the box , when the reality is, it's mixed content.
We don't see many have the DV and HDR10+ layers on a single disc for the entirety of a film, but there's lots of confusion as you can see in this customers video as if you pay close attention his projector throws the Dolbyvision flag at the start. But, when the actual film itself starts, it's HDR10+ source on the disc as the player shows and you never know it switched unless you look. The projector picture settings also confirm it's receiving HDR from the player, not DV. We can replicate this "mixed content" strategy from disc to disc to disc labeled as both and in every case, this was the case with multiple players tested
The customer video file is here:

Not what we like to see happen, but we will continue to dig in.😞
My Hisense TV showed the same thing, hence the confusion and frustration.
