I thought my Google TV stick/dongle was dead, then I disabled one setting

I still value my Google Chromecast with Google TV dongle because I don’t mind when it slows down a little, since I only use it on an older TV to stream movies and shows. So when I ran into a visual problem and thought my dongle was dead, I found it just needed a quick settings adjustment to come back to life. Some have claimed their dongle received an update that broke their Google TV stick, but mine still worked until one day it showed that lovely black screen of death on an old TV that replaced my dead one. Sometimes it’s just one setting that causes the black screen; other times, it’s more complex.
