My avov display setting keep going back to the default setting. I change it from 1080p-60hz to 480p-60hz because I like to see all the words on the screen. I save it and it works fine while I am watching tv however once I turn off my avov and or tv it revert back to 1080p-60hz. Is there a way I can keep it at 480p-60hz without changing it every time I turn in back on?
