Use this control to set your colour quality for the selected display. Increasing colour depth lets you view more photo-realistic images and is recommended for most desktop publishing and graphics illustration applications.
Note: If you need to set your colour depth to 256 colours to run a game or other software program that requires it, right-click the program icon or name on your desktop or Start menu, then click Properties. Click the Compatibility tab and then select the Run in 256 colours check box. Your display will revert to your default colour setting when you close the program.
