Hi, I have a synology NAS I am trying to cast from to a chromecast. I am trying to make it easy for my wife and kids to use but I am out of inputs on my TV. I was thinking I could just use a cheap auto switch HDMI switcher between the TV and my DVR so when they cast something it would auto switch as it sensed the HDMI output from the Chromecast and when they were done streaming it would just flip back to our DVR since the output of the Chromecast would stop. Well I just found out after I bought it that it looks like there is no way to sleep or shut off the HDMI output on the Chromecast. Am I missing something here? Any pointers on how to make this work easy for the family or recommendations on another Chromecast type device to stream from my NAS? Thanks!!
