Hello, all! I retired from the CI biz about 2 years ago. I miss a lot of the technical challenges, but this one is becoming a bit of a headache. HELP!

I installed an Apple TV 4K 32gb device on my own system about 10 days ago. I used input AV5 on the Yamaha AVR. The output of the AVR is connected to a Samsung UN65JS9000 HDR compatible TV. Only 1 HDMI input (HDMI 3 MHL) on the TV is capable of processing HDR signals. If I attempt to enable the HDR feature on the Apple TV 4K 32gb device, I get an error message indicating a compatibility issue.

As a troubleshooting step, I removed the HDMI cable from the Yamaha AVR, and connected it directly to the Samsung TV. I was then able to successfully obtain HDR video from the Apple TV 4K 32gb device.

In summary, it appears the Yamaha RX-A1050 is not properly processing the HDR signal. I have 3 other HDMI sources connected to the RX-A1050. I am limited to one HDR HDMI input on the Samsung TV. The firmware version on the RX-A1050 is current, v 2.65. The VIDEO MODE on the RX-A1050 is set to DIRECT. I am using a Binary (Snap AV) B6-4K-2 HDR (18GBPS) 2 meter cable from the Apple TV 4K 32gb device to input AV5 on the RX-A1050. I am using a Binary (Snap AV) B6-4K-3 HDR (18GBPS) 3 meter cable from the HDMI output of the RX-A1050 to the proper HDR input of the Samsung TV. Both cables are HDMI Premium Certified.

I believe the RXA1050 was purchased in 2015. It supports HDR 10...same as the Apple TV.

I have emailed Yamaha support. After answering numerous questions regarding settings, cable certification, etc., they told me to perform a factory reset. I don't think so. I think they have given up.

I feel I have exhausted all reasonable efforts to resolve the issue on my own.
Hopefully, someone else has encountered a similar issue...and can help resolve. I'm strongly suspecting that the Yamaha AVR is just not capable.

Thanks in advance!

Did you do a factory reset before using the AVR for the 1st time. This isn't crazy, it has become standard practice to default AVRs before installing them - it fixes a LOT of initial issues.
If you haven't done it, then you should follow their advice and factory default the receiver (reinitialize).

Not saying it will fix the problem. But there is a chance.

Also, consider checking whether there is a firmware update on the Yamaha.

Try a different HDMI input on the Yamaha
I came into this game for the action, the excitement. Go anywhere, travel light, get in, get out, wherever there's AV trouble, a man alone.

I can think of a few things.
1: Does the Samsung TV need to be set to 'Extend Mode' on the HDMI input you're using?
2: Have you changed the 4K Mode of the AVR to '4K Mode 1'?
You do this via the advanced menu that you would also use to access the factory initialization. This allows 18Gbps per second to be passed through.
3: Have you swapped HDMI cables? One of the cables may be missing the bandwidth required to enable pass through.
4: Have you checked the ATV's settings? What are the video outputs? 8 bit 4:2:0?

Also... run a backup via the IP setup of the AVR, then perform a factory reset.
This industry is not getting cheaper and cheaper, we're simply convincing ourselves that we have to push the cheapest option to customers.

After I changed the 4K Mode of the AVR to '4K Mode 1', I now have 4K HDR 4:2:2.

Earlier, I was confusing the 4K mode (advanced menu) with the Video Direct (in the main menu).

Thanks to all for your efforts to resolve this issue.
