    Like a lot of people, I setup my new ATV 4K and ran into some issues. I have a Samsung 65" UN65KU7000FXZA and run my BluRay, DirecTV and AppleTV through my Pioneer VSX-1123-K receiver. Was unable to achieve 4K HDR anything above 25hz with the HDMI cables I had, even though they were compatible with 4K. I had a much better picture using SDR, so I purchased new HDMI cables that support 4K HDR. As soon as I hooked them up (directly from ATV to TV) the AppleTV automatically switched to 4K HDR 60Hz and the picture was sharp and vibrant. Unfortunately, as soon as I changed it and ran it through my receiver, it went back to the lack of color I was experiencing with the other cables. My receiver has 4K UHD passthrough, but apparently it doesn't handle HDR. At least that's what I'm assuming. Can anyone help me figure out a solution? Thank you!!

    Looking up your receiver online appears to confirm it doesn't do HDR. Options:
    • Settle for non-HDR "lack of color"
    • Sell the Pioneer and buy a receiver that is compatible
    • Move the Pioneer to some other room and buy a new 4K HDR receiver for your living room
    • See if you can push full audio BACK from your TV to your Receiver and leave the :apple:TV hooked up directly to the TV. ARC? Or maybe optical out (though that typically yields only stereo for many TVs)?
    • Return the :apple:TV4K and buy somebody else's STB that works better with your existing equipment
    • Wait for the infamous "just one software update away" for Apple to maybe make things better for people with your kind of equipment
    Sorry that's not much help... but it does seem to cover up to all of the options.

    I'm in the same boat as you. My receiver is 4k pass through, but the ports are HDMI 1.4, which allows for 4K at a maximum of 30hz. You need a receiver with HDMI 2.0a or higher ports to allow HDR passthrough, and 60hz. I'm planning on running my Apple TV directly to my TV and then using an optical audio TOSLINK cable to run back to my receiver. Hope that helps.

    I had the same 'legacy' receiver issue.
    But no big deal; I just connected everything to my TV first, and it passes through audio fully untouched in LPCM.
    So my receiver still gets DTS 7.1 from the Apple TV in best quality mode running the Infuse app.
