strange monitor brightness behaviour

I have an Adi MicroScan 5P+ 17" monitor which has an unusual behavior
when I turn the brightness knob towards maximum (which is quite often
necessary). Say, I have a white window which covers the quarter of my
screen. As I maximize this window to fill the entire desktop my monitor's
brightness and contrast immediately drop back thus my screen looks dimmer.
When I shrink this window to the previous (small) size brightness and
contrast restore to original level in a couple of seconds. This phenomenon
gets more and more striking as I increase screen resolution.

There is a Matrox Mystique 220 coupled with the monitor but I've tried
several other cards with no success.

I was told that this behavior is normal at microprocessor-controlled
monitors but I don't think so.

Well, what are your opinions about it ?

Thanx in advance,
Levente

I seems as if you monitor is on it's way out, perhaps it is under warranty and can be replaced.  I would look into this as one day the monitor may completely go out on you.

Well this is not a normal problem as you have been told.
there is a problem getting power to the monitor.

1) check to see that it is plugged all the way in to it's socket.

2) check the cable and see if it is broke (even a little) or if it is bulging.

3) move the plug to a diffrent recptical.

4)if none of these work it is the power supply contact a service center and they should be able to fix it for about $200.

Thanx for your opinion. Since the monitor is under warranty (only 4 months old) I will have it replaced.
