Adjust screen brightness


Press the OSD ("On Screen Display") button on the bottom-front of the monitor. Use the other nearby buttons to "navigate" through all the settings, to select "Brightness", and to move the level UP/DOWN.
Wait a few seconds, and the OSD will vanish, by itself.

I'm tring to restore original settings on my LG monitor and keep getting "osd lock" message. Half my monitor is very bright, the other half it 10-15 shades darker.


I held the "Menu" button down for 15 sec. and it unlocked. Then used the Auto Set feature. It didn't work immediately on the two-towned
screen, but corrected itself within 1/2 hr.

Thank you.
