Contrast & Brightness
Adjust your screen contrast to the highest setting. Then using the brightness control adjust the screen so that you can see the all of the blocks in the image (right). There are twenty bars on the image and you should be able to see all of them, the far right bar should be pure white and the far left bar should be pure black.
Setting up your screen Colours
To get the best colour definition from your monitor you should to have your video colour setting switched to 24 bit, or better. The top colour bar should appear as a smooth transition from one colour to the next, starting at and finishing at red. If the image appears speckled or blocky, then changing the settings on your video card will make a big difference to the viewing quality of the images on this site.
Changing these settings is achieved by adjusting video card settings. Don’t worry if you can adjust your video card, dig out the instructions and make the adjustments on the monitor itself.
There are 16 clearly defined patches in each strip. If you cannot distinguish between them towards the dark end in any of the strips, you may need to lighten the respective colour, or darken the other two colours. If you cannot distinguish patches towards the light end in any of the strips, you may need to darken the respective colour, or lighten the other two colours. You can also try to work with saturation controls for the individual colours, if they are available in your system.
Colour Balance (CMY)
There are 11 clearly defined levels in each strip. You will find a relationship between how theseare displayed and how Red, Green and Blue are displayed.
Once again all of the bars should be clearly defined with the darkest colour being discernable from its adjacent neighbour and the lightest colour being pure white.
The panel to the left of the pure white panel should have a noticeable colour cast.
And before you know it you have a perfectly set up monitor. If there are any further problems, I’d suggest an eye test, or may be alternatively a reality check, as the sky on your planet must be different from mine.
