Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The VRDisplayEvent interface of the WebVR API represents the event object of WebVR-related events (see the list of WebVR window extensions).

Note: This interface was part of the old WebVR API. It has been superseded by the WebXR Device API.


VRDisplayEvent() Deprecated Non-standard

Creates a VRDisplayEvent object instance.

Instance properties

VRDisplayEvent also inherits properties from its parent object, Event.

VRDisplayEvent.display Deprecated Read only Non-standard

The VRDisplay associated with this event.

VRDisplayEvent.reason Deprecated Read only Non-standard

A human-readable reason why the event was fired.


window.addEventListener("vrdisplaypresentchange", (e) => {
    `Display ${e.display.displayId} presentation has changed. Reason given: ${e.reason}.`,


This interface was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.

Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
