**Yamaha Japan has released a firmware update for the RX-A4A AV receiver. Once you apply the update you’ll be able to pass a 4K/120 (up to 24Gbps) or a 8K/60 signal (up to 40Gbps) through the AVR. On top of this, there is now support for HDR10+ and more. See bottom of ‘description’ for instructions.**
Surround Sound Processing
If you are running a 4K/120 or 8K/60 capable device with correctly spec’d HDMI cabling and a display that supports the 4K/120+8K/60 formats, you will need to make a change in the AVR settings in order to pass the signal through.
Simply navigate through the AVR menu and select ‘Video/HDMI’.
Then choose ‘HDMI Video Format’.
For the HDMI port(s) that the applicable sources are connected to, ensure the video format is changed to ‘8K Mode’.
