To ensure that your computer screen is displaying colours accurately, it pays to regularly calibrate its brightness, contrast and colour. The most accurate way to do this is with a monitor calibrator.
By using a monitor calibration tool – a colorimeter is the technical name – on your screen and ﬁring a selection of colors at it, any discrepancies can be detected and your computer then programmed to compensate for the color inaccuracy of your monitor.
Of course, no amount of calibration can make a mediocre monitor into a dream display. But by using a calibrator, you’ll at least know that your monitor is performing at its best.
