The models listed below from the manufacturers Denon and Marantz recently experienced pass-through problems as standard in conjunction with selected gaming sources at 4K/120Hz and 8K/60Hz video resolutions.

By taking the HDMI input signal from the gaming source and then passing the corrected HDMI data to the corresponding AVR, the new SPK618 HDMI adapter fixes the error and can deliver a 4K/120Hz or 8K signal.
