Back in the day, when graphics cards started gaining TV output, it was all the rage to connect your desktop to a TV. The idea of playing a DVD on a computer and having it display on a television was an amazing feat. Nowadays, many computers have HDMI-out and it is nothing special.
Lately though, sending video wirelessly to a TV has been the popular thing, mostly thanks to the low-cost Google Chromecast. At $35, it is affordable for all, which makes it an easy impulse buy. Unfortunately, Chromecast works best with apps that support it, and not many do. Sure the list is growing, but it is still small, plus Chromecast screen mirroring is glitchy and slow. Today, Microsoft announces the Wireless Display Adapter, which mirrors the screen of Windows 8.1, Windows Phone and Android devices. Best of all? It does not need individual app support.
