This has been fixed for all units manufactured since May of 2021. All models with serial numbers that end with serial numbers from 70001 (inclusive) upwards are what your looking for. After talking with customer support, they told me that all stock had been replaced, I took the gamble and ordered the AVR-X4700H on 8/17/21 and received one with 72xxx and have no problems with my series X or PS5.
Sorry, there was a problem. Please try again later.Denon receivers made since May shouldn’t have the bug. Mine was made earlier & I can solve the problem this way: https://www.google.com/amp/s/www.forbes.com/sites/johnarcher/2021/04/27/xbox-series-x-hdmi-bug-fix-announced-for-denon-and-marantz-receivers/amp/ Also, this: https://www.google.com/amp/s/www.whathifi.com/amp/news/denon-and-marantz-receivers-built-since-may-are-free-of-the-hdmi-21-bug

Sorry, there was a problem. Please try again later.The description indicates 2020 model, does that mean it needs the SPK618 HDMI adapter?
Sorry, there was a problem. Please try again later.No it was fixed thru an update
Sorry, there was a problem. Please try again later.Earlier revisions do have the issue as reported on many websites. According to Denon, if the serial number ends with 70000 or greater, it is not affected. The one I received from BB a few weeks ago was above that, but I've yet to try 4k/120 or 8k/60.
