About monitors and color work
Although the RGB color model used by computer monitors can display much of the visible spectrum, the video
system sending data to a given monitor often limits how many colors can be displayed at once. By understanding
how color data is measured in digital files and on-screen, you can better adjust color display settings to offset the
limitations of your video system. For critical work, your monitor should be calibrated and characterized for use in a
color management system. At the very least, your monitor should be calibrated to display colors as accurately as
possible.

To speed up previews by adjusting the monitor display
The Use Pixel Doubling preference option speeds up the preview of a tool or command’s effects by temporarily
doubling the size of the pixels (halving the resolution) in the preview. This option has no effect on the pixels in the
file; it simply provides faster previews with the tools and commands.

Adjusting color display for cross-platform variations
RGB color display on a computer monitor varies with the operating system used by the computer. For example, an
image appears darker on a Windows system than on a Mac OS computer (because the standard RGB color space is
darker in Windows than in Mac OS). The Preview commands in ImageReady let you compensate for cross-platform
differences in RGB color display during image preview. In Photoshop, you can simulate cross-platform differences
by using the Macintosh RGB, Windows RGB, and Monitor RGB commands in the View > Proof Setup menu.

RGB color display can also vary between Photoshop and ImageReady. In Photoshop, you can select from several RGB
color spaces when editing images. As a result, images created in Photoshop may use an RGB color space that differs
from the monitor RGB color space used by ImageReady. You can adjust the RGB color display during image preview
to compensate for differences between Photoshop and ImageReady.
