So I'm after a new AVR which can facilitate multiple HDMI 2.1, 4k 120Hz devices. However, just by looking through ALL of the AVR's on Richer Sounds, they all only appear to come with one HDMI 2.1 input!? Even high 4 figure £ flagships!! I know there were initial bugs with HDMI 2.1 AVR's too, which I'm assuming have been fixed now? But why is the current implementation still so poor and are there any new AVR's due which will have all HDMI inputs 2.1 rather than just one? I'm aware the US has an Onkyo which has them all 2.1, but I'm in the UK...
