Look in the menu for a back light brightness adjustment. Some LCDs
have two brightness controls. One adjusts the black level of the
signal driving the LCD (basically doing the same thing as adjusting it
in the video card control panel) and the other adjusts the brightness
of the fluorescent tube. You don't want to adjust it with the video
card's control panel because you lose a lot of dynamic range.

Unfortunately, there is no control for black level signal in this
monitor, there is only brightness and contrast. I wonder, if there is
other ways to control that black level, like dropping the voltages
feeding the backlight or otherwise modifying the circuitry.

Thank you for your response.

You may be able to add a variable resistor in the dimming circuit for the
backlight inverter, some use a simple pot to adjust it.
