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 (specific models listed below) and gaming consoles that support 4K/120Hz and 8K video resolution output.

Update: August 2021 - Quick check — Does your product benefit from the HDMI adapter?

Only Denon models listed below with serial numbers below xxxxxxx70000 are impacted by the HDMI incompatibility issue and require the HDMI adapter to output 4K/120Hz and 8K/60Hz video signals. The below listed models with serial numbers xxxxxxx70000 and greater do not need or benefit from the adapter. If you have one of the affected models and serial numbers, please complete the form below to order the HDMI adapter at no cost.

Affected Models:

Denon AVC-X6700H
Denon AVC-X4700H

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.

Please note: This solution works only with the models listed above that are having problems working with some gaming consoles at 4k/120. Consumers with non 8K Denon AVR models should NOT order the adapter.
