If you click the icon for a secondary monitor, the Extend my Windows desktop onto this monitor check box must be selected to change the settings for that monitor.

Click Medium to display over 65,000 colors, High to display over 16 million colors, or Highest to display over 4 billion colors. Choosing more colors provides better color quality on your screen.

Settings that display a larger number of colors normally require more computer memory and might affect performance on older computers.

Your monitor and video adapter determine the maximum number of colors that can appear on your screen. You can specify the color settings for each installed monitor.

Changes to screen resolution affect all users that log on to the computer.
