AirPlay - Audio only and Artwork. No Video

I thought Infuse can stream content to an AirPlay TV? All I get when I try is the album artwork and that’s it. How do I get videos to work? Are there any limitations?

Hmmm. A 1080p file works, but not a HEVC 4K MKV file.

4K videos aren’t currently compatible with native AirPlay, but you can enable Mirroring to stream these.

This file doesn’t work either.

Is it because I have a TV? And not an Apple TV?

It should support AirPlay 2. I think. It says AirPlay version 25.05. TV is a KD75X8000H.
