Recent-compatible AV from Yamaha, and Marantz will need additional hardware fixes for a bug preventing them from displaying highest-quality video. Currently these models are unable to display video with a frame rate.
Yamaha has announced that owners of its early 8K receivers, including the , will need to replace an internal HDMI mainboard if they plan on connecting an or graphics card. Yamaha says that video playback isn't an issue (unlike for Denon, see below). Yamaha says that affected users should register their devices and the company will advise customers of the next steps here in summer.
Another workaround for owners of all of the below models is to connect the gaming console directly to the compatible TV and then useto feed the receiver.
Affected 8K-compatible receivers
|Denon||AVR-A110, AVR-X4700H, AVR-X3700H, AVR-X2700H, AVR-S960H|
|Marantz||SR8015, SR7015, SR6015, SR5015, NR1711|
|Yamaha||RX-V4A, RX-V6A, RX-A2A, TSR-70|
Most According to one report, the problem is a result of a Panasonic-sourced chipset used for the 8K video sections in affected receiver models.and receivers are able to handle signals at 60Hz but the latest sources can offer 120Hz for smoother motion. However, gamers would encounter a black screen when connecting these sources to a TV via these receivers at 4K/120Hz.
None of the companies has yet advised when the on-sale models will be fixed, especially in the case of Yamaha, and so we would advise holding off on buying one of these receivers for now.
Update, May 27: Adds new information from Yamaha.
