Visit http://get.webgl.org to verify that your web browser and hardware support WebGL. Consider trying a different web browser or updating your video drivers. Detailed error information is below:

The WebBroswer control needs to be in IE11/Edge mode in order to show WebGL content. You also need to enable GPU acceleration. See this link for details: http://stackoverflow.com/questions/25051072/ie-11-webgl-performance-slow-when-using-webbrowser-control

If you are having problems with desktop browsers too, that is most likely a video card driver issue. Be sure you are running the latest drivers for your card.
