Stoltzen RX-1 is HDBaseT receiver for PS42UCH.
With the receiver you get 1 extra HMDI input, balanced audio output and a USB2.0 hub available at the screen.
Note that USB2.0 over HDBaseT is not "HighSpeed" and it is recommended to test compatibility.
In collaboration with Huddly, HuddlyGo has been tested and works with both power and data from the RX-1. Note that this is because HuddlyGo has a USB2.0 mode. This may differ with later updates or other products from Huddly.
