My connection is Sony 55A1 to uhd/hdr in and Apple TV 4K in uhd/hdr out and Sony HW700DS in avr audio.
Problem if you buy on Amazon most of the time is:
- You are getting an older device (not latest revision with revised heatsink)
- Seller usually never include PSU and will want to sell you that separately, while all our devices are shipped with PSU.
- The firmware on the unit is more likely an old one.
So, for Power, you need min 5V2A which the PSU you are using seem capable of doing (according to your pic, I can see output 5V2A)
For Firmware, you need to install drivers on your computer and then connect AVR-Key and run Windows GUI to see which firmware is on your unit and update it if needed. (see AVR-Key usermanual for step by step)
Then when you try in system, put both slides on mid position.
You will also need make sure that you have very good cable for SOURCE to AVR-Key and then from AVR-Key to Display (cable going to audio system is not important in quality)
Get Kabledirekt, bluejeanscables or our cables, min 6ft/ max 12ft for copper.
The cable supplied with ATV4K should be good enough, but then you still need a second one capable of 18Gbps/600MHz
