I just installed the vivid 11 in m 4runner and was driving last night for the first time and the brightness was a bit too high. So I went into the settings and the range of brightness that the slide bar provides vs the amount you move on the bar is way off. I went from 80% to 5% and you could barely see a difference. I tired the night time settings and it was the same lots of movement from the slider bar but almost no difference in the brightness of the screen. Is there another setting that can help with the night brightness or increase the amount the screen actually dims?
