Hello Tom Germijns,
Thanks for reaching Microsoft Community. We're sorry to hear about this issue on your devices. Definitely not the experience we want you to have.
If I may ask, do these devices connected to an organization domain? Does this issue happen to multiple devices? Were there any changes made on your system settings prior this issue happened?
Please be informed that all Surface models can wirelessly connect to compatible displays using Miracast. To do this, press Windows logo key+ P and select Connect to a wireless display. You might also want to see and follow the methods from these articles:
