Brightness fades For no apparent reason and at random times, the brightness/contrast info box appears and the screen gets darker. It will not respond to the panel controls. Any suggestions?

    What power supply? It is plugged directly into an electric outlet. I guess I'm not as conversant with these items so I don't understand the "PSU".

This is a Common problem MOST if NOT ALL, problems like this with this type of fault it is invairably a problem with the Power Supply, in the PSU Electrolytic capacitors dry out and often cause this type of exact problem... It is a relitively simple fix, by replacing the caps with new ones... Any good shop should be able to fix for a modest fee.. OR if ya know anyone handy with a soldering iron maybe they could do it for you there are generally about 4 - 6 to replace... in the PS section, just do them all to be safe..

HOW TO SET BRIGHTNESS OF THE SCREEN?

Hi,

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.


On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.



Thanks....

Brightness

most monitors get darker with age -- for a while you can counter this by turning up the Brightness and Contrast controls, but this only gives you a little extra time (and probably speeds up the decay process anyway).

Can't read the screen

That's just the contrast and brightness of your screen. all you need need to do is to hit 2nd and then hit the up arrow. you will need to do this several times for it to get darker. Everytime you do it you need to hit the 2nd key and then the up arrow.
