Help configuring Roku device settings, using Roku OS features such as screen mirroring, adjusting display type and audio settings, using Guest Mode, and assistance with software updates.
How do I disable Roku Ultra (4800X) from turning on automatically when I power up my Samsung 55" TV. It's annoying because the remedy is for me to power up my Denon avr-s720w and select cable to watch cable TV.
Your Roku Ultra is always on. Try unchecking "1-touch play" under Settings->System->Control other devices. Your TV may have settings that affect this as well.
