Calibrate display color in Windows 7
The colors you see on your screen will vary depending on your monitor, graphics cards settings, lighting and more, yet most people use the same default Windows color profile. And that means a digital photo you think looks perfect might appear very poor to everybody else. Fortunately Windows 7 now provides a Display Color Calibration Wizard that helps you properly set up your brightness, contrast and color settings, and a ClearType tuner to ensure text is crisp and sharp.
To start the Display Color Calibration Wizard follow these steps. Press the key combination Windows Key + R to open the Run dialog. Type DCCW in the Run dialog and press Enter.
The wizard will take you through many steps of instructions followed by setting and correcting the basic color settings, gamma, brightness, contrast and color balance. In the end, you are shown a wizard for ClearType tuning to ensure text is shown correctly on LCD screens.
