5-11Lesson 1 Configuring and Troubleshooting the Display
decision is that when you arrange your displays on the Settings tab, the location
of the monitor icons accurately predicts what happens when you move your
mouse pointer between displays. For example, assume that you have two dis-
plays side by side. One of the displays is a 19-inch monitor and one is a 15-inch
monitor. You can arrange these displays on the Settings tab so that either the tops
or the bottoms of the displays are aligned. If the tops were aligned, whenever you
move your mouse pointer from the bottom of the bigger display toward the sec-
ond display, the pointer would get “stuck.” To get the pointer over to the smaller
display, you would have to move the pointer upward to the point where the bot-
tom of the smaller display was. Although it seems as if it might not be a big deal,
losing track of your mouse pointer because of this arrangement is a common
complaint among multiple-display users.
