Apple TV Works Now!

Just wanted to mention that Apple TV (the app on macOS) doesn't work when using dummy displays, but with smooth scaling, it works fine. I was told that Apple sorta blocks untrusted displays due to DRM.

Thanks for the info! Yes, Apple TV app uses HDCP which is a copy protection mechanism and is incompatible with Virtual Displays (dummies, sidecar etc). Native scaling does not have this issue.
