I don't use traditional cable. I use an Apple TV for HULU and Netflix. I have tried to hook up to the XBOX, assuming it was just a HDMI pass through. I have my Apple TV connected, but all I get is sound and a black screen. Any ideas? Is there a specific HDMI cable requirement? I have seen people hook up a PS4 to an Aople TV, so I know it is not just cable boxes.
