Resolution and Colour Depth
The resolution of the LCD is the sharpness of the image it can display. Resolution is measured by the number of pixels (individual dots) displayed on the entire screen. In general, the more pixels the LCD can display, the better the image.
The number of colours the LCD can display is measured by how many bits the LCD uses to represent each pixel:

All these video modes can be displayed on an external monitor. However, if you disconnect an external monitor that was attached to your computer and then start the computer, the LCD may revert to a different resolution than the one you chose for the external monitor.
Adjusting the LCD Brightness
There are 9 levels of LCD brightness (1: Dimmest ~ 9: Brightest). The default LCD brightness setting is level 5. Whenever you change the power source, the brightness level is changed to the following setting:
• | When operating on AC power | : Level 9 (Brightest) |
• | When operating on battery power | : Level 3 (Slightly dimmer) |
Once the LCD brightness has been changed, the changed setting will be maintained after restarting the computer. When the power source is changed (AC to battery or battery to AC) while in operation, both the default brightness settings described above will be restored.
You can adjust the LCD brightness by pressing <Fn+Up Arrow> or <Fn+Down Arrow> on the keyboard.
