ntTake a long look at your computer monitor. Is the contrast and brightness right? Have you calibrated the color correctly? Have you ever calibrated the display at all? For the amount of time you spend staring at the pixels that monitor generates, calibration should be something you do at least once. It is not a difficult process and Microsoft Windows 7 includes built-in applications that make the process really simple.

Factory defaults

Factory defaults

The first step the Display Color Calibrator asks you to do is to load the factory defaults. If you are like most people that is what the monitor is set to, so you really don’t have to do anything but click the Next button.

Color calibration explanation

Color calibration is often necessary because manufacturers and retailers like to up the color saturation of the monitors as they leave the factory to make them stand out to consumers.

Better

Better

Assuming you made adjustments, you can look at the quality of your display before and after calibration. If you did it right, your display should look better after calibration. If it doesn’t, perhaps you would like to use a piece of hardware to calibrate your display? We’ll get to that in a bit.

Clear Type is on

Moving on to the Clear Type calibration is an important step – at least as far as I am concerned. As someone who spends hours looking at text, I really need my text to be displayed as clear as it can possibly be. All my Windows PC operate with Clear Type turned on.

The next screen talks about native resolution. For LCD monitors in particular, this is a very important consideration for proper calibration. An LCD will always display a better quality image when it is in its native resolution.

The next four screens show text boxes of varying attributes. Each individual is likely to pick a different combination, so don’t be persuaded to choose what I have because this is really a calibration test that matches text to your eye.

Make your calibration choices and you will reach the end with a display with better attributes than you stared with. However, if you really want to get a true gamma, brightness, contrast, and color calibration and adjustment, you will have to invest in a specialized piece of hardware, like the Eye-One Display 2.
