Black screen with AppleTV and PrimeVideo

[massimoaria]

Hi,

when a dummy monitor is connected, Apple TV and PrimVideo apps show a black screen when playing content.
The movie menu works fine but when I start to watch a movie/series the screen remains black while audio works fine.
PrimeVideo and AppleTV work normally if I watch something through the browser.

Closing BetterDummy app, AppleTV and PrimeVideo Apps turn to work normally.

Hi, yes this is listed in the known issues. This is a limitation in macOS imposed by design. See these as well:
