Not cheap, but this product looks like it might be ideal for an HDMI input for the Portsdown.

HDMI Input Option
Re: HDMI Input Option
I have got one. It's not supported yet. The £10 dongles in the metal cases work fine, also not supported but you can buy ten of them for the price of the elgato.

Re: HDMI Input Option
The Elgato is expensive, ridiculously so when compared with their stream deck, but would offer a potential path to UHD. I wonder if the Jetson Nano would support it?
Re: HDMI Input Option
I was thinking that the StreamDeck could make a great repeater controller too.
