hdmi not working mac resolution not supported

I also tested various methods with a Mac mini and external displays of different types, and it failed consistently, as now expected. The Apple TV works fine with HDCP and external displays, and in what should be bitter irony, fourth-generation Apple TV apps from Netflix, Hulu, and others, firms that can’t stream DRM-protected video in OS X to an external monitor are perfectly able to while wrapped in the embrace of tvOS. This also prevents using HDCP over AirPlay, because AirPlay-supporting devices apparently also don’t expose to third-party developers whether the associated device is an authorized device. As such, it is currently not possible to detect if the display is HDCP compliant, nor is it possible to engage HDCP. Apple doesn’t expose the required information to third parties (via an API that developers can use) to determine whether HDCP is in place, according to Adobe.Īpple does not currently publish their APIs to detect/engage Output Protection.Non-Apple firms offering digital streaming or other digital playback options through browser plug-ins, HTML5 video, or freestanding OS X apps will always report an HDCP or other error for an external display.iTunes can detect the connection correctly, and play the highest-resolution video on HDCP-capable monitors.The accurate answer to HDCP and externally connected Mac monitors has three parts: Only iTunes in OS X supports external monitors Finally, I summarize what each major streaming service notes about requirements and troubleshooting, and finish up with how to fix DRM errors even with a built-in display by resetting or removing Silverlight.
