Monitor Adjustment

When your monitor is properly adjusted, you will see 11 distinct zones in the image below, from pure black to pure white. If you do not see all 11 zones, use your monitor's contrast and brightness controls to make adjustments.

The greyscale below presents 24 shades of grey from pure white to solid black. The pure white block at the far left should merge with the pure white bar along the top, while the second block of very light grey should display a bit darker than pure white. The solid black block at the far right should merge with the solid black bar along the bottom, while the block just to the left should display a bit lighter than solid black.

Below are boxes, one should be absolute black. Nothing on your monitor should be darker than the black box. Look at the black border around your monitor. It should be as black as that box. And nothing should be lighter than the white box. The grey and white boxes should have no pink or blue tint.


Under the 0% column, there should be NO color, just plain bright white. If it is gray or dingy or has a color cast, adjust your monitor until that area is plain white. Under the 100% column, the colors should be recognizable process colors with a full rich representation. If they appear washed out, your monitor is probably set too bright. The best way to set this is to adjust your gamma curve up or down until the 10% shade difference between the 90% bars and the 100% bars can just be seen. If you adjust it too dark, you will not be able to see a difference between 90% and 100%. As you lighten them up, just at the moment you start to see the difference between 90 and 100%, STOP.


The cyan bar will always appear correct first but keep going until you start to see the 90% tint in the magenta and black bars as well. The yellow bar may never come in correctly, don't worry about it. The magenta and black bars are the most important.

Once your white point is set and your tint bars look correct, you should be ready to surf this and other web sites with confidence.
