I am unable to pass Dolby Vision through my receiver after this last update. Everything worked before the update and my other equipment, Oppo 203 and Firestick 4K, passes Dolby Vision.
Anybody else having this issue?
Apple TV 4K, tvOS 12

it says published September, but that doesn’t mean they haven’t edited it to reflect anything they might have changed through this update
I’ve just discovered my own issues following the update -(
Try another HDMI Cable
If the HDMI cable isn’t certified at 18 Gbps (“High Speed” HDMI.) Apple TV will downgrade the signal to HDR10
Has the 4K/UHD Television had a required software update applied to enable DV?
All of my cables are Certified 18Gbps cables. I have switched the cables and all other Dolby Vision equipped devices work with this cable. Plus it worked right up to when the ATV4K was updated. This leads me to believe the problem is unrelated to cables.
same thing just happened to me. Apple TV 4K with an Onkyo NR-TX676.
Dolby Vision worked without issue for months and suddenly this week it's not even available in the video options.
Swapped HDMI cables with my UHD Bluray player where Dolby Vision is working without issue and still nothing.
Reset the Apple TV, rebooted all my devices. No luck.
I'm using 18gbps cables right now, but just ordered 48 gbps cables to see if that changes things.
The extra bandwidth should stay unused, as an HDMI 2.0 port will never output more than 18 Gbps of actual data. HDMI devices will have to follow the specs. If the new cable works where the previous one did not, then the issue was with something else than the bandwidth capacity.
Hello, are you aware of what was changed in the latest ATV4K update that has resulted in my Onkyo receiver not being able to pass Dolby Vision. Dolby Vision has been working prior to this update. Additionaly all other capable equipment still passes Dolby Vision properly.
I too have Dolby Vision problem since the update, before that Dolby Vision is flawless. I have Xbox One X and Fire TV 4K that are working fine with DVD with the Onkyo TX-NR 787.
I also have Onkyo TX-NR656 and even on that model Apple TV Dolby Vision doesn't work.
That’s more for higher speed
There’s V2.1 now and you should make sure to use an RF-shielded HDMI cable to avoid any interference and don’t get one that’s too long either, the longer the cable run is, the likelier it is that the wiring itself will act as a low-grade antenna, picking up RF frequencies.
Not to say any of this will resolve your problems.
Hello again. I am still having this issue.
Like I mentioned previously, the issue seems specific to my Apple TV 4K and my Onkyo receiver (Onkyo NR-TX676). I picked up 48gbps cables just to be sure. From my Apple TV 4K to the Onkyo, Dolby Vision is never an option since the last update (worked flawlessly for months before). From Apple TV 4K directly to my TV, Dolby Vision works without issue. Turned on Dolby Vision at that point and plugged back into my Onyko and it won't pass anything. Needed to hook it back up to my TV and change out of Dolby Vision in order for the HDMI to even handshake on my Onkyo again.
I have an LG UBK90 UHD Bluray player hooked up to my Onkyo too. This passed Dolby Vision without issue. I hooked up my Apple TV 4K to the HDMI cable that my LG UBK90 was using and the exact same issue is present. This means it's an issue with Apple TV and the Onkyo device.
I have also posted about this on reddit's apple TV subreddit and it looks like quite a few other people with similar devices are having the same issue. Here is a link to that forum: https://www.reddit.com/r/appletv/comments/b78faf/apple_tv_4k_dolby_vision_suddenly_stopped_working/
I have encouraged them to come and post on this thread too.
Is there any way we can notify Apple about this issue so we can get it fixed? If anyone could point me in the right direction it would be appreciated.
A quick google search of Onkyo Dolby Vision not working (some not even mentioning Apple TV) indicates this was happening in late 2017. Perhaps there’s an issue with this product?
Look up troubleshooting for the product page 141-142
Issues popped up for a number of users immediately following an update. Nothing has changed with my setup in months. The onkyo hasn’t been updated in months because it has been disconnected from my WiFi. This is an Apple TV 4k issue
Not saying Apple tv didn’t change things. The updates admittedly mess with stuff and it’s a case of figuring out a solution.
@ giordano243
There was a firmware update January 16 for TX-NR787 Open Source Software Download.
Did you install it? You said it’s not been updated. It’s possible they could soon issue another to fix Apple’s recent update

The thing that really tells me this is an issue with the Apple TV is that my other device outputs Dolby Vision without issue and hooking the Apple TV up through that hdmi cable still has the same issue. It’s defeating going through all the normal troubleshooting and still coming up empty. A bit out of my control at this point unfortunately.
Once again I agree with you. No amount of troubleshooting will fix this issue. Unfortunately we are at the mercy of Apple and or Onkyo to issue a fix. Until then I'll have to use other equipment in my setup to watch Dolby Vision. :(
I looked at the page saying there was an update.
In any case that was prior to march 25 12.2 Apple update.
Hopefully Onkyo releases another to resolve issues with whatever Apple did. A lot of times other equipment has to play catch up following Apple updates.
Good luck!

No Dolby Vision through my Onkyo TX-NR787 after latest update.
