Permissions-Policy: display-capture directive

{{SeeCompatTable}}

The HTTP {{HTTPHeader("Permissions-Policy")}} header display-capture directive controls whether or not the document is permitted to use Screen Capture API, that is, {{domxref("MediaDevices.getDisplayMedia", "getDisplayMedia()")}} to capture the screen's contents.

If display-capture is disabled in a document, the document will not be able to initiate screen capture via {{domxref("MediaDevices.getDisplayMedia", "getDisplayMedia()")}} and will throw a NotAllowedError exception.
