I bought a new Vizio D-series 70" TV a few weeks ago and I'm having trouble getting CEC features to work with my Apple TV 4. Are certain HDMI cables not compatible with CEC? I know that most likely the problem is firmware problems on Apple TV and/or the TV itself, but I'm just trying to rule out factors that I can control.
Both the Apple TV and TV are running the latest firmware's already.
