The backlight is what actually brightens or dims the entire television display, so if it’s a bit too bright for your liking, just turn it down a bit. And if it’s not bright enough, crank it up to a level that’s suitable. However, make sure to leave the “brightness” alone unless you’re re-calibrating your TV’s picture. For day-to-day adjustments, backlight is what you want.
