Bootup your computer and display your Windows Desktop. Make sure yourmonitor stays on for at least half an hour before you begin, so that itis properly warmed up.


Seta pure black image on the monitor so you can adjust the brightness. Toget a pure black image, do the following: Choose Start, then ControlPanel, then Display. This will open the Display Properties dialog box.Click the down arrow next to the representation of the desktop color inthe Color field. Choose black from the color palette, then click OK.

Open a screen with a plain white background soyou can adjust the contrast. One of the best ways to do this is to open aword-processing document without any text in it. Gradually reduce the contrastsetting of your monitor until the white area of the screen begins to lookslightly gray or off-white. Then gradually increase the contrast until thewhite area on your monitor is pure white. This will give you the proper whitebalance. Now you've got your monitor ready for peak performance.
