Monitor calibration can make your computer work session a pleasant one.

Brightness, gamma and other video settings influence the quality of your PC viewing experience. Brightness settings determine how your monitor displays shadows and dark colors. If you set brightness too low, screen content will be difficult to see. If you set the brightness too high, on-screen images and text will lose contrast and shadows will lack definition. The Windows 7 Display Color Calibration tool can help you adjust your screen's brightness so dark colors appear vividly and details do not get lost in the shadows.


Step 1

Click the Windows 7 Start button and type "dccw" (without the quotes) in the search box at the bottom of the Start menu. If Windows asks for an administrator password or confirmation, enter the password or click the "Continue" button to continue. The Display Color Calibration window will open.

Step 2

Click the "Next" button at the bottom of the window. The next screen contains instructions on how to locate your monitor's "Menu" button. Follow the instructions, then click "Next."

Step 3

The next page describes how to adjust your gamma settings. Since you only want to correct brightness, click "Next" to skip to the next screen.


Step 4

Continue clicking "Next" until you reach the screen that says, "Find the brightness and contrast controls for your display."

Step 5

Click "Next." The program will display a set of images that show examples of too little brightness, too much brightness and good brightness. It will ask you to adjust your monitor's brightness so that its images look like the "good" image.



Step 6

Adjust your monitor's brightness as requested, then click "Next" to proceed to the next screen. The next screen displays an image of a dark suit and a dark shirt. The program will ask you to adjust your monitor so you can distinguish the shirt from the dark suit. Follow those instructions and click "Next" until you reach the end of the calibration session.

Step 7

Click Finish to close the program.
