Denon, Marantz and Yamaha all affected. And maybe others too.
Awesome though it is that the next generation of consoles and PCs are moving video game graphics on with brilliant new features like 4K at 120Hz, variable refresh rates and automatic low latency mode switching, it’s fair to say that the step up is causing more than a few technical hitches. I’ve already reported in recent weeks on various issues LG’s OLED TVs have had handling the output of Nvidia’s RTX 30 graphics cards (despite these TVs being the most advanced gaming TVs on the market). Now it appears that next-gen gaming trouble lies in store, too, for the latest AV receivers from Marantz, Denon and Yamaha. All three of these esteemed Hi-Fi and AV specialist brands have announced new receiver ranges in recent months that carry HDMI 2.1 ports supposedly capable of handling all the new features the Xbox Series X, PS5 and new PC card generations can throw at them. Unfortunately, though, according to German website Heisse Online, based on original reports in computer magazine c’t, a bug in the HDMI implementations of all these new receivers has rendered them incapable of passing through either 4K video at 120Hz or 8K video at 60Hz from the Xbox Series X and Nvidia PC cards.
