connecting apple tv 4k sony receiver and samsung 4k tv
Can I connect my new Apple TV 4K to a sony receiver which is connected to my Samsung 4K TV?
Apple TV 4K
Set up your Apple TV - Apple Support
Yes, you can connect that way. Modern AV receivers function very well as hub for connecting multimedia devices.
Does the receiver support 4K passthrough (HDMI 2.0 ports with support for HDCP 2.2)? If it doesn’t, then the 4K functionality will be reduced to HD. See the receiver manual for details.
What model is the receiver?
Alternatively, you can connect the Apple TV to the TV’s HDMI input and use the HDMI-ARC connection to pass audio to the receiver (if the receiver and TV both have ARC ports).
