Adjusting the convergence of the picture

Red, green, and blue signals in your monitor converge and create the colors you see on your screen. If the convergence is not set properly, images or text on your screen may appear fuzzy or blurred or you may get a “rainbow” effect with several colors forming the edges of images on the screen. If your monitor is exposed to external magnetic fields over a period of time, you may need to change the convergence to get a clear, distinct picture. Or, you may want to change the convergence according to your personal preference.
