Get A Denon or Marantz Receiver with Working HDMI 2.1 Today!


You may have heard about Denon / Marantz (owned by Sound United) updating their 2020 AV Receivers with a working HDMI 2.1 input. This corrects the problem with the HDMI boards that caused them not to work properly with the Xbox Series X and some computer graphic cards. All 2020 8k receivers from Denon and Marantz that tout a single HDMI input manufactured after May 2021 will have updated HDMI 2.1 boards. But, when you are shopping, how do know that you are buying a Denon or Marantz receiver with working HDMI 2.1? There are a couple of ways.

Which Receivers Does This Affect?

We’re glad you asked. In general, the models affected are marketed as 8k with a single HDMI 2.1 input. The model numbers are listed below:

DenonMarantz
AVR-A110
AVR-X6700H
AVR-X4700H
AVR-X3700H
AVR-X2700H
AVR-S960H
AV7706
SR8015
SR7015
SR6015
SR5015
NR1711

So, now you know the models. But they need to be manufactured after May 2021. To know you are getting a Denon or Marantz receiver with working HDMI 2.1, you’ll need to do a little more investigation.

Buy the right one, you won’t need this.

Denon / Marantz Will Tell You…Eventually

If you are shopping online, your only hope (most likely) is to order and find out if the HDMI 2.1 works after you receive your Denon / Marantz Receiver. If you have a compatible display and an affected device, you can just plug them in and see. But, even easier, is to go to the SPK618 registration page, and enter the serial number of your new receiver. If your Denon or Marantz receiver has a working HDMI 2.1 port, it will spit out a response that says you don’t need the free external HDMI 2.1 adapter.

Check the Serial Number

If you are shopping in person, you can guarantee that you are getting a Denon or Marantz with a working HDMI 2.1 port. Before you lay down your hard-earned money, take a look at the serial number. Any number that ends in 70001 or higher will be a unit with a functional HDMI 2.1 port.

Conclusion

What we are really waiting for is for Denon and Marantz to announce their 2021 AV receiver offerings. We expect those announcements to come in the fall. Until then, at least you can now get a fully functional receiver. If you have one of the older receivers, the SPK618 is on backorder with about a 6-month wait according to our sources. Surely, it is worth it for those with affected devices to shop local to ensure they get the newer models with the updated boards.
