By initiating the on screen menu, you navigate to the brihghtness etc.This can also be related to contrast. Get a keyboard with zoom keys that will make it east to enlarge text.Mine is a logitech wireless S510 and its a great bargain and comes with mouse.the best solution is, however to buy a 42 inch or larger display and use that as you monitor. I can never go back!
SOURCE: brightness/contrast
Sometimes all you have to do is press the left or right adjustment buttons, one will bring up contrast adjustment, the other brightness.
Otherwise simply browse through the menu settings.

The screen itself is starting to go bad which is why your having to turn up the brightness to 100% just to see something. Replacing the screen would cost more then the whole lcd monitor itself so its best to get a new one.

I assume that you already try this monior with other PC and still get the same problem. You may have to open it up and inspect the inside, look for bad components such as capacitors in the power supply, the problem can also be inthe backlight inverter circuits also.

Post back what you see inside so we can guide you further.
