So I moved into the world of 4K today after the PSU in my old Samsung LCD decided to let out it’s magic smoke (I’ll look into replacement parts to see if I can get it working again, but the main TV has been upgraded to a QLED 65" Samsung… which is nice).
Anyway, I grabbed a new AppleTV 4K to go with it, setup was very straight forward, logging in grabbed all my old apps (in the right places too) and it’s running nicely. Netflix happily plays 4K content but Amazon Prime Video fails everytime I attempt to play 4K content with an error message saying to try again later. HD content works fine.
(speed isn’t an issue on 100MBit cable).
There seems to be some threads around the net talking about this issues from 2017/18 but nothing more recent. It’s also worth noting that 4K content plays just fine through the new TV’s built in Amazon app, it’s just the ATV.
Does anyone have any further information on this issue and if it was ever resolved? Or what changes to settings might help??
