On my pi 3, I have fixed hot plugging HDMI by adding HDMI hot plug to 1, boost to 4 and mode to 2 in my config.txt file.
However, when I plug it into my LG HD TV/monitor it just says no signal. Any ideas? I know it's working as it's fine on my other TV.
This is a full HD TV and it works on my other TV, so I've no idea what else to try. I need this to work as it's for retropie.
