Display Problems

Here are some typical display problems and their solutions:
The display is blank
Display Auto Off may have gone into effect. Press any key to activate the
screen.
You may have activated the instant security feature by pressing Fn and
F1 simultaneously. If you have registered a password, type it and press
any key. If no password is registered, simply press any key. The screen
reactivates and allows you to continue working.
If you are using the built-in screen, make sure the display priority is not
set for an external monitor. To do this, press Fn and F5 simultaneously
(once). If this does not correct the problem, press Fn and F5
simultaneously again to return the display priority to its previous setting.
If you are using an external monitor or television:
■
Check that the monitor or television is turned on.
■
Check that the monitor or television's power cable is firmly plugged
into a working power outlet.
■
Check that the cable connecting the external monitor or television to
the computer is firmly attached.
■
Try adjusting the contrast and brightness controls on the external
monitor or television.
■
Press Fn and F5 simultaneously to make sure the display priority is
not set for the built-in screen.
■
If no image appears on the screen after switching displays, press
Fn + Spacebar simultaneously to change the resolution.
The screen does not look right
You can change the display settings by clicking a blank area of the
desktop with the Touch pad secondary button, then clicking Properties.
This causes operating system to open the Display Properties dialog box.
The Appearance tab of this dialog box allows you to choose the colours
for the screen. The Settings tab allows you to choose the screen
resolution.
The built-in screen flickers
Some flickering is a normal result of the way the screen produces colours.
To reduce the amount of flickering, try using fewer colours.
To change the number of colours displayed:
1. Point at the desktop and click with the secondary button.
2. Click Properties, and then Settings.
3. Change the Colour quality option and click OK.
