How to Change Color Depth

Your computer's monitor (either LCD or CRT) uses color depth to control how many shades of color to use when displaying images. The lower the color depth, the muddier the image; while larger color depths permit more lifelike representations. Color depth can typically range from 1 (monochrome) to 24-bit, providing a palette of millions. Although 32-bit color depth is possible, the color variations may be difficult to discern on screen. Changing your computer monitor's color depth is easy and could save you memory, as well as improving image appearance.

Things You'll Need

• PC or Mac with LCD or CRT color computer monitor

Instructions

Windows XP

1. Right-click on the open portion of the Windows XP desktop, choosing "Properties." Next, select the "Settings" tab item. A drop-down menu will appear listing your choices for "Color Quality."

2. Changing the screen resolution within the "Settings" area will affect the range of choices available within the "Color Quality" drop-down. Depending on how much graphic memory is available, the range of color-depth possibilities could shrink. Reducing screen resolution does the opposite.

3. Vista users should click on the "Start" button. Click on "Control Panel." Click "Appearance and Personalization." Choose "Personalization" and select "Display Settings." Pick the "Colors" drop-down menu, selecting the highest available color-depth (often 32-bit).

4. Mac OSX users should select the "System Preferences" item under the Apple menu. Pick the "Displays" icon. Choose a preferred screen resolution under the "Resolutions" area, then select the number of colors to display under the "Colors" item.

5. CRT display users should proceed as was explained for LCD users.
