Question: ATV doesn't stick to 4K HDR...need help!
Hi, I have an ATV 4K. I have very good quality HDMI cables. When I turn on my system (ATV > Yamaha RX-V581 > Samsung 4K TV), the ATV is set to 720 SDR. I have to manually set it to 4K HDR, or Restart the ATV and when I check, the format will be set to 4K HDR.
I'm trying to figure out why I have to set it all the time or Restart the ATV. Again, I've tried numerous cables and the same thing occurs with all of them.
Am I missing something?
