Dell Latitude screen will not adjust for brightness

\015 My Latitude D520 screen brightness will not adjust. When using the hot keys the brightness contol appears on the screen and moves up and down with the buttons but the screen itself stays constant at about 25% brightness. I have changed settings in the control panel but to no avail. The laptop did this shortly after purchase but rectified itself after a couple of days. Its now out of warranty and has been like this for a month.\015

I have a new-to-me Dell LCD monitor, passed on to me by my husband, who has no instructions for it. All my images are printing too dark and with too much contrast, and I am unable to adjust the contrast from the controls at the foot of the screen. When I press the contrast bar I get a screen that shows both brightness and contrast adjustments, but I can only access the brightness control. Are there basic instructions available for how to navigate the adjustment bars? Thanks, Janet
