No Chromecast? No problem, at least after Windows 10’s November update, which enabled the Edge browser to cast media to Miracast- or DLNA-equipped devices with just a few clicks—though beware that the implementation has some quirks, and won’t work with DRM-protected streams from Netflix, Hulu, and the like. YouTube works just fine though!
To beam a video to your TV, open it in Edge, then click on the three horizontal dots in the upper-right corner of the browser. A drop-down menu appears; click Cast media to device. After a moment, a black window with the names of all nearby Miracast/DLNA devices will appear. Simply choose the one you want and after a few minutes, it should begin to play.
Should. In our tests, casting to a Roku box proved tricky, while Vimeo delivered more consistent results than casting YouTube videos. Regardless, it’s a nifty feature. Try it out!
