According to this, Comet Q should be able to stream video from Nintendo Switch.
When I connect Comet Q to the Switch without power supply, Comet Q turns on, but the K&M and Video status icons are red, and the Switch display is still on.
When I connect the official Nintendo power supply to the Comet Q, the status icons turn yellow, and the Switch screen turns off as if docked correctly, but I get no video through Comet Q.
So far my Comet Q works with only 1 of my 3 devices (Android phone works, but a laptop and a Switch do not) which is very disappointing.
