This page will assist you in adjusting your monitor for viewing our site.

Setting the resolution

Using your mouse, drag the side frames of your browser window wide enough apart to see both ends of the red line below. If this is not possible, you will need to increase the resolution setting of your monitor. Generally, you will find this setting in the "control panel" of your software(windows). The suggested resolution is 1024 X 768 pixels.

supplementary comments in italics are mine



Setting the color palette

The three bands below appear as a rainbow of colors starting and ending in red. If your monitor is properly set, the topmost band will display a smooth transition from color to color without banding or speckling like the two lower bands. If the top band is not continuous, you will need to increase the number of colors your monitor displays to either thousands or millions of colors. Generally, you will find this setting in the "control panel" of your (windows for example) software.



Setting the Color Balance

In the square below, the upper left quadrant represents pure black and the lower right quadrant, pure white. The gray quadrants should be neutral gray (neutral grey is composed of equal parts: yellow, red, blue: that's why it can be used for colour balance). If they have a noticeable (color: yellow, red, or blue) tint, adjust the color balance of your monitor (if possible) to obtain a neutral grey. Use the controls built into your monitor or adjust the software settings for your graphics board.




Setting Brightness and Contrast

The strip below contains 10 shades of gray from pure white to pure black. Adjust the brightness and contrast of your monitor until the 10 shades are distinctly visible. Use the controls built into your monitor or adjust the software settings for your graphics board.


Fine Tuning

Use the grid below to fine tune your brightness and contrast settings. Step back from your monitor and compare the numbered boxes to their surround. Adjust your monitor brightness and contrast until the 1.80 box appears to have the same value (grey tone) as the surround. Use the controls built into your monitor or adjust the software settings for your graphics board. This is visual judgment call and as long as your close you'll be ok.
