Lost 2160p on vero after update

I can play the video currently without issue. So I’m not sure that a new update is what we need here. I am using an NFS share however with some buffer tweaks, because there are high bitrates at the start of the video.

I’d disable Sync Playback to Display. Even if not using passthrough, Adjust Refresh Rate being enabled is better.

I’d also screenshot your settings so we can check them. Sometimes people don’t set up audio to use HDMI and it’s on PCM (you hear sound, but this should be changed).

Try the Jellyfish 120Mbps clip. I can play this smoothly off the internal storage (eMMC) without any system tweaks.
