If you are NOT a gamer, this piece of news probably ain’t gonna affect you. But if you are a GAMER, then you woll be happy to learn that there is a middleware in the form of an external HDMI signal converter to properly convert the HDMI 2.1 FRL signal for your XBox Series X and PC gamig rig (using nVidia 3000 series GPU) to a compatible signal accepted by the AVR. Here’s a schematic set-up of HDMI adaptor to the gaming console and the AVR.

The SPK618 HDMI adapter solution is designed to remedy a compatibility issue between select Denon A/V receivers that support 4K/120Hz and 8K video resolutions and select gaming consoles that support 4K/120Hz and 8K video resolution output. If you experience a black screen and no audio when trying to pass through 4K/120Hz or 8K signals from gaming devices connected to the 8K input of the Denon A/V receiver, this adapter will help you to get a proper gaming experience. You will be able to register on this page starting May 15th to receive the SPK618 HDMI adapter at no cost. Meanwhile, click here to download the Instruction Manual on how to use the adapter.
Not the most elegant solution but hey, what do you expect when the product itself is already DOA for gamers. I’m not a true blue gamer hence I’m not particularly excited over the X8500H eventual roll out of the HDMI 2.1 board upgrade.
