AppleTV 4K Disney Plus app black screen with sound...

This was helpful in that it lead me to another solution which worked for me. In case someone else finds this post and has a similar issue to me ... 'Went into video and audio on my Apple TV and downgraded 1080 HDR to 1080 SDR and that did the trick.'

Just switching to SDR didn't work, I had to turn of match content in the video audio settings. I am guessing it was switching to HDR from SDR even though I had set it SDR.

I believe the problem is not Apple but the Disney+ App. Apple TV works fine for Netflix and Amazon HDR.

Contact Disney Support and after you convince them your equipment is not at fault and have the correct speed cable and are plugged into an HDMI port that is HDCP 2.2 compliant, they will likely tell you they are aware of the problem and are working on it with no ETA on a fix. In the meantime set the Apple TV 4K to send 4K SDR and Match Dynamic Range to OFF and that should fix the issue so you can watch picture, but no HDR. Live with that until Disney+ fixes it.

Some have luck because their TV is very new and recognizes Dolby Vision for HDR. If yours doesn't then the SDR fix should allow you to watch the movie until Disney figures out how to send proper HDR10 so it works as well as Netflix.

However, I discovered another problem with AppleTV 4K and the Fubo TV 4KHDR app. I discovered this problem while watching the SuperBowl. FuboTV sends HLG form of HDR on their 4K HDR program and the Apple TV4K does not support HLG. Several references to it claiming it does are published but not on Apple Support that I could find. So, FuboTV had a green screen with sound when I tried it. I have another tuner that does support HLG and it received the Fubo TV 4K channel just fine. If possible, Apple TV 4K device should upgrade to HLG compliance so it works with their FuboTV 4K app. programming

All these problems means that we are all early adopters, field testers for the companies, and the people making this stuff are still trying to figure it out. It doesn't help that the FCC doesn't issue a standard for the equipment makers to meet. So everyone has a better idea and we end up with stuff that is buggy or doesn't work at all. Be prepared to buyreplacements when they figure out what works!

I had the same problem. It’s weird because all other apps stream just fine with no problems and Disney Plus is the only one that plays audio with a black screen. I fixed it by switching my Apple TV 4K to HDMI 1 from HDMI 2 and now it works great. It’s a really weird issue and I don’t know how it works like that but for some reason Disney Plus doesn’t like that HDMI port.

Worked for me too - had to downgrade to 1080 SDR.

Disney+ should keep the free trial going until this is resolved.

Some older TV's don't have HDCP available on all the HDMI inputs which is why switching to a different input works. Has nothing to do with those who are having to shut off HDR to see most movies on Disney+ So far, I found only one movie that Disney correctly display's HDR.

Changing Inputs did the trick for me. Thank you for the tip!😊

Reboot fixed it for me.

Seems odd to me that after buying a streaming device that does 4K HDR on several apps (Netflix Amazon) just fine that anyone would be satisfied needing to set the device to output Disney+ to 1080 SDR. Unless of course your TV is only capable of that lower quality setting. Disney or Apple needs to fix their app on Apple TV 4K as anyone who owns a 4K HDR TV should insist on it. If Netflix and Amazon can get it right so should Disney.

Having the same problem. I can't believe the answer is to change the input. (hard for me to do given our AV cabinets. Why would Netflix, Hulu, Apple TV+ and other 4K HDR sources work fine, but just Disney Plus needs a different input??!

turning on matching dynamic range and match frame rate with 4K HDR didn’t work for me. I got the same issue with audio playing with no video. I had to revert back to 4K SDR and turned match dynamic range and match frame rate off.

jg001 thank you for the suggested fix. I changed my settings and it worked for me as well! As a matter of fact, my screen looks more crisp now with 1080 SDR than with 1080 HDR. I believe the 1080 SDR may have resolved my freezing / connection issue too! Thanks a million!!

You have to go into settings on you Apple TV and go to audio and video settings. Change from either 4k hdr to 4k sdr or from 1080p hdr to 1080 sdr. This is only an issue with some of the content on Disney plus.

Switching from 1080p HDR to 1080p SDR worked for me. In my case it's a Samsung smart TV but not a 4K. I can stream Apple TV and purchased iTunes movies in 1080p HDR no problem, but since these are native Apple apps, most likely they determine the TV's capabilities through HDMI / HDCP negotiation, and adjust accordingly. It would seem the Disney+ app doesn't do that. If the Apple TV is set to 1080p HDR, that's the feed Disney+ gives.

Thankfully I found this post with a quick Google search, and it was a 30-second fix. 1080p SDR it is!
