Google Chromecast + $6 Google Play credit – $29.98 @ Amazon

Enables use of the Chrome browser from your phone, tablet, laptop or desktop for content on your big screen via one of your HDMI inputs.

The Chromecast is not a streaming device of local digital content. In other words, it does NOT play digital music and videos that is stored locally on your network drives or computers. However there is a work-around for this:

Use PLEX Media Server. If you don’t already have it, here’s the link:

Once you download it and point it to your files,it will act as a proxy and allow your music and videos to be played on your HDTV using the Chromecast through the Chrome browser. Simply launch the PLEX Media Manager in Google Chrome browser. Pick a file to play, Hit the Google Cast button and you’ll get seamless playback of your own files.
