I just got an OLED55C8. I won't have a cable or antenna connection to it, nor will I have any other devices physically connected to it. So there are no input sources to choose from. Everything I view will be coming through WiFi. Whenever I turn on the TV, it comes on with the TV source selected. And because I have no signal sources connected to it I get a random noise picture and sound. If the volume was up high on the previous viewing, the random noise is pretty loud. It can be pretty jarring at times. Is there some way I can set it so that upon power-up one of my streaming apps, such as YouTube TV or Netflix, is selected? Or can it come on with the volume off and on the home screen? If not, is there some way I can at least set the default volume level used at power on?

Hi I've got the LG OLED55B7V. I have connected a Chromecast to HDMI4 and USB power from USB port 3. Is there any way to not turn off usb power on this USB port, or any other USB port, when turning off the TV? Since webOS still doesn't have a Spotify app i need a Chromecast to listen to music, and so i would like to have the Chromecast powered from the TV but the TV turned off. I know i can use screenmode to only turn off the screen, but since i can't enable that with a single button from my remote control this isn't a good enough solution.
