Rather new at this, I called my son to install it, I realized quickly that the commissioning of the HDMI key was a biblical simplicity! I'll use it to cast the movie or the series of my choice tablet towards my TV (I have invested in NETFLIX 8 euros per month). Youtube tested under the same conditions, it's perfect. Just as it is from an application to run.
Installation is very simple: to show little or no manual, you just perform "maneuvers" that appear on your computer by plugging the key on a TV Hdmi jack, Launch the app from your tablet . Your Chromecast (connected to the TV) and your tablet, phone, computer, will recognize.
