not something i played with, but i think you either set it in moonlight or you can configure the resolution in sunshine https://localhost:47990/<-- on the legion go directly you can replace
localhost
localhost
with the ip of the legion go if you want to change it remotely
Alright, I've gotten this far, but it needs a undo command line in order to apply the do command line, I don't know what to put there, I've been using the example pdf provided by the sunshine team.
