Is there a possibility to connect his Xbox One S to the pc and then to use it with a ps4 controller?
Playstation 4/5 controllers are not compatible with Windows!
To my knowledge, mirroring the screen of the Xbox One S on your PC is only possible with a capture card.
Hmm, thank you, and do you know whether I can also play older Xbox controllers such as the 360 or Xnox one with the Xbox One S?
You can use an Xbox One controller on your Xbox One S without any problems.
I'm not sure about the Xbox 360 controller because I haven't used or used a 360 controller on the One myself
Xbox 360 controllers are not working on the One
