VRDisplayCapabilities: hasExternalDisplay property
Deprecated
Avoid using this feature in new projects. Development of the WebVR API halted in favor of WebXR. This feature may be a candidate for removal from web standards or browsers.
Consider using the following features instead: WebXR.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
Note: This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
The hasExternalDisplay read-only property of the VRDisplayCapabilities interface returns true if the VR display is separate from the device's primary display.
Note:
If presenting VR content would obscure other content on the device, this will return false, in which case the application should not attempt to mirror VR content or update non-VR UI because that content will not be visible.
Value
A boolean value.
Examples
See VRDisplayCapabilities for example code.
Specifications
This property was part of the old WebVR API that has been superseded by the WebXR Device API.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. Read Meta's Porting from WebVR to WebXR guide for more information.
