Denon and Marantz integrated HDMI 2.1 to their receivers for the first time last year, and while it offered plenty of new features, there’s a bug with 120Hz/4K gameplay on Xbox Series X that requires some additional gear.
But what about those who have older receivers? If you already own a 2018 flagship model from the Sound United brands, they’re providing a factory-fitted update to include HDMI 2.1 (without the Xbox bug) for $600, according to Forbes and HD Guru.
Owners of the $4,000 Denon AVR-X8500H and $4,499 Marantz AV8805 may make use of “8K/60Hz upscaling and pass-through, 4K/120Hz pass-through, HDR10+, Dynamic HDR, HDCP 2.3,” as well as other HDMI 2.1 functions like VRR, QFT, ALLM, etc.
If you’re in the market for a new high-end receiver, check for updated models with an A after the model number. The Denon AVR-X8500HA will cost $4,299 at retail, while the Marantz AV8805A will cost $4,799. Starting June 15th, you may upgrade to a Denon or Marantz system for $600.
