DENON & Marantz Offering Free HDMI Adapter to Fix Xbox Series and PS5 HDMI 2.1 Bug With Receivers

If you are one of the many who recently bought either a DENON or Marantz audio receiver that supports 4K120fps and 8K video output, you may have noticed some compatibility issues with both the PS5 and Xbox Series consoles. Specifically, the receivers having troubles outputting those options when running with HDMI 2.1 on PS5 and Xbox Series. Well, turns out there’s a fix, though it involves more hardware.

As announced on both the DENON and Marantz websites, owners of any of the affected audio receivers (listed down below) are now qualified to receive a free SPK618 HDMI adapter, the solution to allow full 4K120fps and 8K video format through the receivers.

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.

Receivers with known issue

  • Denon AVR-A110
  • Denon AVR-X6700H
  • Denon AVR-X4700H
  • Denon AVR-X3700H
  • Denon AVR-X2700H
  • Denon AVR-S960H
  • Marantz AV7706
  • Marantz SR8015
  • Marantz SR7015
  • Marantz SR6015
  • Marantz SR5015
  • Marantz NR1711

If you own any of these receivers and are experiencing black screen when trying to output content at 4K with 120fps, then it’s highly recommended to register for the adapter. Of course adding more hardware to what is already most likely a cramped space may not be ideal, but it’s definitely better than having to buy a whole new set.

As noted on the sites, registration to receive the SPK618 HDMI adapter won’t start until May 15.
