Display Rotation
27
NOTE
While the display is rotated:
• Do not use the Extended Desktop. (The touch pad or the digitizer may fail to operate
properly.)
• Do not set the display resolution larger than the resolution of the internal LCD.
The computer's performance will decrease somewhat.
If moving video is played while the display is rotated, the picture may not be displayed
properly or the sound may be broken up. This problem can be corrected by rotating
the display to [Primary Landscape].
The touch pad scroll, zoom, and data zoom functions do not work while the display is
rotated.
The display cannot be rotated when the [Command Prompt] is set to "Full Screen".
If the display is rotated when the resolution is set to 800x600 pixels, depending on the
Windows specifications, incorrect values may be shown for the resolution displayed in
[Screen resolution] of [Display Properties]. Continue using these settings, without
changing [Screen resolution].
