Yeah, I've switched to HDR10 as well and have experienced no issues since then, and since it looks like all the major streamers support it, I might just keep it this way!
Hi dtwdcaordatl Krobar1 Spitfire53,
Greetings, and thanks for keeping us posted!
We'd like to take a closer look at your problem. Can you please provide the following information?
Note: With a compatible TV and streaming channels, you can stream 4K Dolby Vision with certain Roku streaming players. But if your Dolby Vision-capable TV was made before 2018, you might be unable to watch Dolby Vision content at 4K resolution. Netflix and other streaming services won't play 4K Dolby Vision if the TV doesn't support higher frame rates, like 60 frames per second.
You may also want to check out the Roku product comparison chart in this support article to determine if your player supports Dolby Vision.
We look forward to hearing from you soon and hope you'll find this info useful.
Cheers,
Roku Community Team
Hi,
Having the exact same issue here. Worked fine for 6 months and now just a black screen for Dolby Vision content. Audio playback is normal. Issue is across all apps (Netflix, Max, Peacock, Paramount, Disney). I’ve updated to the latest software on the TV, Roku OS and Apps. Dolby Vision works on the native TV version of these apps (with the exception of Max, which is why I bought a streaming stick 4K in the first place).
Streaming Stick 4k
LG C9 OLED
LG 83 B4
Streaming stick 4K
Worked fine for 3 episodes each of Paradise on Hulu and Acolyte on Disney+ and then just got a black screen with sound, after the TV entered Dolby Vision. Don't remember exact date it started, 1st week of April for sure, as I signed up for a Hulu and Disney+ and Max subscription at end of March.
Shows on Paramount+ and Peacock work fine with Dolby Vision. All shows work fine with LG Web OS and no other changes were made to all setup configurations or cabling etc., prior to this bug happening.
A video of the issue would show a black screen with sound.
I like Dolby Vision and Dolby Atmos on our 5.1.2 home theater setup and do not want to downgrade to HDR10 just to get things to work.
A video of the issue would show a black screen with sound.
RokuJohnB I'm using an LG C1 with a Streaming Stick 4K. The issue happens with Netflix and Disney+ for me, probably happens with others but the family had already started whining that the "Roku was broken" and so I disabled Dolby Vision.
Troubleshooting steps I have tried so far:
Removed the AVR from the chain - No change
Force TV type to 4K HDR (Without DolbyVision) - Fixes it but obviously kills DV support
The issue started after the firmware update at the beginning of the month. Worked perfectly until then.
All of the TVs listed in this thread support DV 60hz and everyone who has so far replied was working fine until the recent firmware update.
It seems there are quite a few of us with this problem caused by the recent firmware update, will Roku investigate?
Hi, Howardp4 Spitfire53 Joeblow99 Krobar1
Thanks for keeping us updated!
Our team would like to investigate this further, and we could use your help by gathering a few details from the Roku device.
Please provide the following information:
Once we have this info, our team can continue with the investigation.
Appreciate your help and looking forward to your response!

RokuTakashi Here you go.
Model: 3820EU2
Serial: X250025R4YP
Device ID: SOJA3485R4YP
OS 14.5
Netflix: 61.2222 Build 1301011
Disney+: 1.50 Build 2025040200
Tracker: YP-162-487
Advanced Display Settings (Thought this might be relevant):
Auto Adjust Refresh Rate: On
Dolby Vision Always On: Off
HDR Subsampling: 4:2:0
As mentioned the display just shows Dolby Vision and then is black but sound works fine; the OSD / Playback menu wont appear. Pressing back causes it to change back to the menu display mode and the picture comes back.
If I go back to the menu and retry play back it will usually work after 2-4 attempts so this issue is intermittent for me (Approx 75% failure rate though).
I attach 2 images of the LG HDMI diagnostics, one is of the menu screen and the other is once I start playback of the Dolby Vision series.
For me, it's been happening on all channels when I attempt to play Dolby Vision content. Playing non-DV content on the same channels works properly.
I outlined the troubleshooting steps in my first post. The issue first emerged early this month, though I'm not sure of the exact date.
A video wouldn't be of much use - I try to play DV content, and the screen goes black, with a DV logo in the upper right corner (and the TV picture settings do switch to what they normally are for DV content).
