hi, @Svendus ,
this video plays only in 1080s (HD) at my place, are you sure it’s 5.7k?
I’ve fiber internet 200-300mbps stable international download speed and ~100mbps upload, able to play 8k videos without issues. As I know anything above 4k is coming as vp9 from google for sure, but even those lower resolutions are transcoded to vp9…
Regarding viewing h265 directly in Edge: it work sonly if there is a hardware decoder available on that machine, if it’s not then it doesn’t play, regardless of browser.
