When the display is rotated and the screensaver starts, the screen may go black for approximately 1 minute, depending
on the type of screensaver. Change the type of screensaver.

If the same screen is displayed for a long time, this may leave an afterimage.
The screen becomes disordered
The screen display may become distorted if the resolution or number of colors is changed, or if an external display is con-
nected or disconnected while the computer is operating. Restart the computer.
Switching between internal and external displays does not work
The display destination cannot be switched while a video such as an MPEG file and a DVD Video are playing. Stop playing
the video before switching the display destination.
The display cannot be changed and the operation of the Touch Pad and the
touchscreen do not match the display angle
When some applications are running, the display may not be rotated and the operation of the Touch Pad and the touch-
screen may not match the display angle. Press the Ctrl + Alt + R key to rotate the display to the landscape mode. After
exiting the application, rotate the display, then start up the application again.
If the problem persists, restart the computer.
