Since Version 66 of Chrome it is possible to use the Presentation API There is a W3C Draft for it since 2019-04

The Example at

• https://googlechrome.github.io/samples/presentation-api/

will work in Chrome 66+ and given an error message

ReferenceError: PresentationRequest is not defined (Your browser may not support this feature.)

for other browsers when clicking presentationRequest.start(). On Chrome 66+ a selection dialog appears

and after picking the desired screen is used in full screen mode.
