At the time of purchase, the display setting is preset for an external display. If you connect
an external display, the screen is displayed on the external display.
When there is no display to an external display,
• Check your cable connection to the external display.
• Confirm your display is powered on.
• Check the settings for your external display.
Try changing the display by pressing
Fn + F3 .
When displaying only through an external display, if the computer is shut down by using
the suspend or hibernation function, there will be no display on the LCD unless the exter-
nal display is connected when operations are resumed. In this case, connect the external
display.
Has the computer been set to the power-saving mode?
To resume operation of your computer from ECO mode, press any key.
To save power, your computer may have automatically entered the suspend or hiberna-
tion mode. (
"Suspend/Hibernation Functions")
Set [None] for [Wallpaper] in [Start] - [Settings] - [Control Panel] - [Display] - [Background],
and then press [OK]. Then, once again try changing the resolution. After the change, be
sure to restart the computer.
If an image is displayed for a prolonged period of time, an afterimage may appear. This
is not a malfunction. The afterimage will disappear when a different screen is displayed.
High-precision and advanced technologies are necessary in the production of color liquid
crystal displays (color LCDs). Therefore, if 99.998% or more of the picture elements are
functioning properly), no defect is considered to exist.
Try changing the display by pressing Fn + F3 .
When an external display not compatible with the power saving mode is used with the com-
puter, the external display may no longer display properly when the computer enters the
ECO mode. In such cases, turn off the power to the external display.
