4320p settings (UI + video)



I don’t know if i’m in the right section. If not please (re)move this thread.

I just recently bought a 8K TV from Samsung (900D) and a 8K media player that has a Amlogic S928X SoC. I use Kodi to mainly stream 4K BluRay’s from my Synology NAS. 2160p (60fps) plays without any issues.
I’m experimenting with 8K. So I got a couple of 8K files that i’m testing using kodi. In the Kodi system settings i’m using the 3840x2160p resolution without any issues playing media. When I use the 7680x4320p resolution the movies kind of lag. Not completely, but most of the time. Is this normal?

Second. 8K – HDR – 60fps – AV1 do play, but sometimes there’s like a small stutter. The audio has no issues and 8K 30fps plays fine without any issues. The best way I can describe the playback is like: [Smooth – Stutter – stutter – Smooth – Smooth – Stutter (etc.)] When using another Android video player I don’t experience any issues. Is there something in the settings I should be aware of that might help creating a flaweless playback. 

If you need more info let me know.
