Okay, I asked this question on the wrong product. I feel pretty stupid because it says in the product name that it is compatible with Android devices. Next question for the community: How do I delete a question?

I use the controller with the PC

The best thing to do is to contact our customer service directly (digitec@digitec.ch). Your request can then be examined individually.

There is no specific information on the compatibility of this controller with the Nvidia Shield TV. However, we advise you to buy the controller designed by Nvidia for optimal compatibility: NVIDIA SHIELD Controller

Theoretically, yes. What is certain is that you can connect an official PS4 Dualshock controller.
