The Yamaha RX-V6A is affected by a 4K/120Hz video bug when used with certain devices.

Ty Pendlebury/CNET

recent 8K-compatible AV receivers from Yamaha, denon and Marantz needs additional hardware fixes for a bug that prevents them from displaying the highest quality video. Currently, these models cannot display video with a 4K resolution and 120Hz frame rate.

Yamaha has announced that owners of its early 8K receivers, including the V6A, need to replace an internal HDMI motherboard if they are planning a Xbox series X or Nvidia RTX 30 Series Graphics Card. Yamaha says so Playstation 5 video playback is no problem (unlike Denon, see below). Yamaha says affected users should register their devices and the company will inform customers about next steps here in the summer.

Meanwhile owners of new 2020 and 2021 8K-compatible Marantz and Denon receivers may request a free hardware dongle designed to troubleshoot: 4K / 120Hz play video. Denon’s external SPK618 HDMI adapter fixes compatibility issues with the PS5, Xbox series game consoles and graphics cards. Denon users can sign up for the adapter here and Marantz owners can sign up here.

Another solution for owners of all models below is to connect the game console directly to the compatible TV and then use it HDMI eARC to power the receiver.

Most 4K TVs and receivers can process signals at 60 Hz, but the latest sources can offer 120 Hz for smoother movement. However, gamers would encounter a black screen when connecting these sources to a TV through these receivers at 4K/120Hz. According to one report, the problem stems from a Panasonic-sourced chipset used for the 8K video sections in the affected receiver models.

None of the companies has yet advised when the sales models will be repaired, especially in the case of Yamaha, so we recommend that you buy one of these receivers for the time being.
