brightness vs backlight level

[JoeClark]

Hi all,


on my LG 43UJ6500 TV, there is a brightness level and a backlight level. both increase or lower the brightness. What is the difference between the two? If i want to lower or increase the brightness of my TV, which of those two should I use?





I didn't find the right solution from the internet.
