Streaming Stick 4K shows a black screen with Dolby Vision content.

I've been using a Streaming Stick 4K (3820R2) with a Hisense 55U8K for about a year with zero issues, until about two weeks ago. Lately, when I play Dolby Vision content on any app, the screen will g...

I'm getting the exact same behaviour with Streaming Stick 4K and an LG Oled through an Arcam AVR. The problem started with the Roku firmware update at the beginning of this month. Sometime going back to the Netflix Gui and starting playback again will fix it but it is not consistent. I always get the same behaviour when it breaks which is a black screen with Dolby Vision detected and sound working.

The only solution I have found is to force the TV type in Settings to 4K HDR in order to disable Dolby Vision. HDR10 works fine.

    I am having a similar issue, but so far only with DV on Hulu and Disney+ that I signed up for at the beginning of the month. Worked fine for about 3 episodes of what we were watching , and then just black screen with sound. Spent some time chatting with Roku support last week, but no fix yet. Paramount and Peacock work fine with the 4K streaming stick to my LG B4 oled, very strange.

    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?

      • Is this happening on all channels you are trying to access, or is it on a specific channel?
      • What troubleshooting steps have you taken so far?
      • When did the issue start?
      • Could you share a video clip or photo with us?

      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).
