Apple TV as a Source
Connect the Apple TV’s HDMI output to the capture path used by Void Video, then confirm the incoming signal in Blackmagic Desktop Video Setup.
Choose an output format supported by the complete HDMI chain. Source-side frame-rate and dynamic-range matching determine when the Apple TV changes signal format; Void Video detects those changes and processes the resulting input.
After video appears, configure the theater screen in Screen Configuration. The Apple TV’s current output format does not define the physical screen.
