The screen
The screen looks blurred or out of focus.
m The viewing angle may not be optimal. Tilt the display on its hinge until
the screen looks better.
The screen is too dark.
m When you first turn on your computer, it may take several minutes for the
screen brightness to “warm up,” especially if you’ve chosen a high setting.
m The screen brightness or contrast may not be optimal for the surrounding
lighting. Adjust the brightness or contrast setting.
m The screen dims automatically when the battery starts to run low. You may
need to recharge or replace the battery before you can turn up the
brightness.
The screen is flickering.
m This problem sometimes occurs when your screen is set to display the
maximum number of grays or colors. Try adjusting the contrast control, or
select fewer grays or colors in the Monitors control panel.
There are ghost images or black dots on the screen.
m When the computer is left on for many hours, temporary images may
appear on the screen. Put the computer to sleep. The longer the computer
was left on, the longer it will take for the images to fade, but they will
eventually disappear.
The pointer moves too fast or too slowly.
m You need to adjust the pointer’s tracking speed. Open the Mouse control
panel and choose a more comfortable setting.
