Use One Computer to Chromecast Different Windows to Multiple TVs

A few months ago, we moved Mattermark into a shiny new office. Today, I was using the quiet time before the new year to setup some TVs we mounted in order to display different teams’ metrics. I wanted to do a wireless solution, so I bought three Chromecasts (one for each TV). I plugged them in, got them setup, and then was horrified when it seemed as though I had to get three different computers to control the three Chromecasts. If you Google around, you won’t find a solution, but I found a way to cast different browser windows to multiple TVs from one computer. Here’s how you do it:

  1. Go to your settings in Chrome
  2. Add a new user for each different TV you want to cast to (screenshot)
  3. Install the Chromecast Extension for each of those browser windows
  4. Click the Chromecast Icon in the top right corner of Chrome and cast your browser to a different Chromecast for each different screen you want to display
  5. You’re all set!
