The root of the problem appears to be an incompatibility between the DRM management system in iOS 16 and devices with older firmware, including HDMI adapters. DRM systems help protect digital media from illegal copying and distribution, and as they evolve and receive updates, they can become incompatible with devices that do not receive updates of their own. In this case, it seems that the firmware of HDMI adapters is causing problems with iOS 16. Unfortunately, no solution has been found at this time, and it’s unclear if this restriction will be permanent. This is a frustrating development for users of Apple devices who have been relying on HDMI adapters to stream DRM-protected content. It’s worth noting that this issue only seems to affect devices running iOS 16, so users with older versions of the operating system may not experience the same problems.
