Hi,
This icon indicates the BRIGHTNESS control, more properly called BLACK LEVEL. It adds or subtracts an offset, or bias, into the red, green, and blue signals. This control should be adjusted so that black picture content displays as true black on your monitor. Misadjustment of this control is the most common problem of poor quality picture reproduction on computer monitors, video monitors, and television sets. Later in this document, I will explain how to set this control properly. The setting is somewhat dependent upon ambient light. Modern display equipment is sufficiently stable that frequent adjustment is unnecessary.


This icon indicates the CONTRAST control, preferably called PICTURE. It applies a scale factor (gain) to the red, green, and blue signals. It affects the luminance (proportional to intensity) that is reproduced for a full white input signal. Once BRIGHTNESS is set correctly, CONTRAST should be set for comfortable viewing brightness.

The gamma can be controlled through Video Card utility which can usually be accessed by going to display properties.

Depending on your video card software you may be able to right click your desktop, select properties, select settings tab and then choose advanced, towards the bottom. In there you may find a tab called Monitor and under that tab you may or may not (depending on your video card software) be able to adjust your color correction settings(gamma & brightness & contrast).

. Right click on the desktop and then select Properties

2. Click on the Settings tab and then click on the Advanced button.

3. Click on the Color Correction tab and you will see settings for Brightness, Contrast, and Gamma

rjmusvi, Sometimes the VGA connector at the rear of the PC needs to have it RESEATED 4-8 times to see if it returns the screen to NORMAL colors being displayed on the LCD panel!!! Do this with the POWER OFF to both PC and LCD monitor!!! Also check to see if any of the pins in the monitor to pc plug are bent or pushed down into the connector body. 12fixlouie on fixya

the control IC should be replaced

Your video card (or driver) is probably to blame.
Try hooking a new monitor up to the computer to test this.
If so, try the advanced settings in control panel. Many cards give you the ability to manually alter the picture.

If that doesn't fix it, replace the card.

Does your scanner software give the option to choose different modes...grayscale, color, black & white?? This sounds like it's scanning in grayscale....if you can change it to black & white, the background should remain white.

Do you mean no picture at all but a white screen or a feint picture?
