Using the Test Images

This module provides six different test pictures selectable from the drop down box at the top of the window.

Grey Scale Test Image

You should be able to see the following:

  • A grayscale with 20 different sections

  • The darkest section pure black

  • The lightest section pure white

  • No hint of any color in the gray tones

If you cannot see all of the 20 sections, use your monitors contrast settings or the Gamma slider to correct this. If black is not pure black, try to darken the monitor, if white is not pure white, try to lighten it. If you see any colors in the gray tones alter the color balance settings of your monitor or the Red, Green and Blue slider.

RGB Scale Test Picture

You should be able to see three strips, each with 16 sections of red, green or blue tones. The darkest sections should be pure black, the brightest should be pure red, green or blue. If you don't see all sections of a color strip, try to lighten or darken this color.

CMY Scale Test Picture

You should be able to see three strips, each with 11 sections of cyan, magenta or yellow tones. The brightest sections should be pure white, the darkest should be pure cyan, magenta or yellow.

  • If you cannot see all cyan sections, try to lighten or darken red

  • If you cannot see all magenta sections, try to lighten or darken green

  • If you cannot see all yellow sections, try to lighten or darken blue

Advanced Test Pictures

The following three pictures show you the abilities of your monitor at three points of the gray spectrum. If you cannot see all of the details, don't be worry, or buy better hardware.

Dark Gray Test Picture

You should be able to see 10 different rectangles of dark gray within a black box. The chart shows you 1% steps from black.

Mid Gray Test Picture

This picture shows you 11 gray rectangles within a 50% gray box. You should be able to see all of the rectangles except the middle one. The rectangles represent the steps from 45% to 55% gray.

Light Gray Test Picture

You should be able to see 10 different rectangles of light gray within a white box. The chart shows you 1% steps from white.
