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.

Press the e button on the bottom of the screen (far left) and use the arrow buttons (2nd from right) to adjust the brightness.

if it is an lcd monitor make sure the refresh rate is set to 60hz and the resolution is at least 1024X768 then try to push auto adjust again. To get to the refresh click on the advanced button when the display properties is open.

try by using the contrast and brightness button

I just bought an Acer 19 inch this morning and I am assuming you have the same controls on the bottom of monitor. On mine I push the menu button twice....the left arrow once to select the brightness slider.....push the menu button again to turn slider red and active...then use your left or right arrows to adjust brightness...afterwards you use the menu to get you back to the exit button and that's it....I hope Don

Your logic board need to service.
