TIPS
Can I use a different desktop background in each display?

click Desktop & Screen Saver . On the second display, you see the Secondary Desktop
dialog. Use that dialog to set the desktop picture or color, as described in Chapter 14 .

to 4 to display the Arrangement tab and then select the Mirror Displays option (
changes to ).
