Video format issue

Plex Players
1

For the past few weeks, I’ve been running into an issue: when I try to play a high-definition video—such as one in 4K—it won’t start unless I downgrade the format, for example to a lower HD resolution. On the other hand, in the Plex app on the TV, they play in their original format without any modifications.

Play where?

Which kind/brand of TV?

Please provide the contents of the Plex media info.

I watch it on the iOS app, and on the TV via a Fire TV Stick. I’m attaching a screenshot of one file, but it happens with all of them when I view them on my iPad.

If the file is DoVi profile 8, it’s an issue in 2026.20.0. Would need to see the advanced details of the file to confirm.

It has been fixed in the just released 2026.22.0 version. Keep checking the App Store for when it becomes available to you.
