LG Monitors include a setup overlay that adjusts various settings of the monitor, such as brightness, contrast, color, screen ratio and volume, even when it's disconnected from a computer. You are free to adjust these settings without fear of permanently impairing the display, because LG included a Reset function in addition to this myriad of controls. Selecting this option erases any adjustments you've made and restores the monitor's factory default condition.
