Calibrate your monitor
However, if the images are less than satisfactory, it is more likely that you need to calibrate your monitor.
There are two main comments we hear about images on a computer screen.
Both of these are easily solvable:
The quick and easy way to adjust these two controls on your monitor are as follows:
Too dark or too light test
Color Scales testThis pattern displays 20 intensity levels for each of 10 principal colors, going from black up to maximum brightness. Use it to check and adjust the color intensity scales for the most important colors.
Smooth tonal gradations testThis is a bit more difficult than simply dialing in tones on the monitor. Nonetheless, it is critical that this information is understood and used by you if you are to get the most from images you see on your computer screen.
Quick test (figure 4).
If these 2 x two images don’t look very different (the ones on the right should be much better than the ones on the left) then you need to adjust your video card settings.
If your video card is set to 16-bit , you will likely see a graduation that looks similar in both the left and right sample, but the tones will be composed of dots (known as dithering). You will definitely need to adjust your video card.
There are distinct bands on the images on the left. There should be no bands on the images on the right -- it should be a smooth gradation of tones.. If there are, then your video card needs to be configured as outlined below.

Video card / configMost video cards are set at the factory to create 256 different shades of color, including the shades of gray. For non-graphical purposes (e.g., word processing, email, etc.) this is more than adequate.
For graphics, photographs in particular, this is not enough tones to do justice to an image.
Some monitors, especially older ones, will only make 16 shades of gray!
You will need to adjust your setup configuration to more shades of gray to see images as they should be seen.
Most older systems are set to 16-bit color. Most newer systems are configured at the factory for 32-bit color.
To view photographs, it is essential that your system be at least 16-bit.
If you can, use 32-bit color for the most realistic colors.
You will need to set this adjustment in your "setup" or "configurations" controls of your computer. The location of these controls vary based on your operating system and whether you are on Windows, Mac or another system. Refer to your instruction books or a knowledgeable friend if you need help setting your video card to a higher bit depth.
