When I connect the Apple TV in any of hdmi 2.2 that are in the back of the Receiver, the receiver doesn’t recognize the HDMI, but if I connect it in the front hdmi Aux imput, the receiver does accept the image in 4K but no HDR. All the cables, receiver and projector are new and 4K, hdr, etc with all the new technology. Any thoughts on this?
Apple TV 4K, tvOS 12
The HDMI port on the front of that model receiver is listed as supporting lesser video, so that is presumably an HDMI 1.4 port, while the ports on the back side are HDMI 2.0/HDCP2.2. That would explain the ‘no HDR’.
Page 163 in the Onkyo manual lists this for troubleshooting:
❏ No image from a device connected to HDMI IN jack
Thanks for the reply. I’m aware that the front hdmi it’s 1.4, the real issue for me, are the back hdmi slots, that when I connect the Apple TV, the Receiver says hdmi not supported (all the cables are top of the line and up too date), and I get no image. But with the front 1.4 hdmi I have no issue.
I found a way to switch the back hdmi inputs between standard and enhanced, and noticed that the image goes trough perfectly in standard mode but in 4K SDR. But when I switch to enhanced mode there’s no image, this happens with my Apple TV 4K and the PS4 PRO. I believe that the issue it’s with the HDR. Any ideas on how to troubleshoot this issue?
