" adjust the brightness and contrast on the PICTURE menu "
If this is incorrect, I see LG lets you call them. It's over at the right side of the screen at:

How do you adjust brightness on this TV? If I go to the "Picture" option in the menu it only lets me select between presets. There are no general "brightness" and "contrast" options.
