This is a follow up question to: Change output to HDMI after tv has turned off
This solution works partially. I can turn off the TV and turn it on again and get the screen back on my TV. However this does not work in the following case:
Turn on both devices. Let the raspberry stay on the login screen. (Don't log in) Turn off the TV. Wait a few hours. Turn on the TV.
Now the screen is just black. It does not say "No input" as it would when nothing was connected, but the screen stays black, no matter how much I type on the keyboard.
Now, considering that it seems like the TV is receiving something, or that it can at least sense the presence of a device, then the first solution obviously worked. But again, no joy over prolonged periods of time.
Is there a way to fix THIS? :)
