Thanks, larry. That makes a lot of sense. Wish they'd spelled that out in the User Guide! I'm not finding anything about using the auto adjust or nightlight feature on the help page at Amazon either.larryb52 said:what Amazon told me was with auto brightness on and in your darkest room you set the level you want and than hit the large - at the bottom to set your preferred minimum brightness. To set your auto max setting you do the opposite you find the brightest place you will read and adjust it to the level you like and hit the + at the top to lock it...I tried this with the tech and it works or least for now it does ...btw if you get in an area that it in between it adjusts between those 2 levels...hope that made sense...
