I just run mine without ever connecting it to the internet.
I run an Apple TV (shock, walled garden!), as it is the only device I’ve seen that consistently matches frame rates properly on the output.

This is why I often refer to 4K as UHD: The WCG and HDR being available to consumers is far more impactful than end users having a few more pixels.

(Also because I’m a snarky pedant, and consumer 4K UHD is only 3840 wide, while DCI4K is actually 4096)

It’s a joke. They actually use FXP orchestrated by a third party, unencrypted.
It’s very efficient.
