External VGA Port
Your WinBook has an external VGA port for directing video output to an
external monitor. (Figure 7.1) You can connect an external VGA or SVGA
monitor to your notebook through the VGA port on the rear of the system.
You can direct output to the LCD, the external monitor or both through the
display properties. Refer to the Help and Support Center for further infor-
mation on the options available in the display properties. Your external
monitor might require that you change the video driver from the default
driver for the LCD screen. Check the Help and Support Center for specific
instructions regarding video drivers.
A higher resolution on your external monitor might also mean a slower
refresh rate, the speed at which a monitor sends a new image to the screen.
A cathode ray tube (CRT) sends an image vertically down a screen one
line at a time. The whole screen is thus refreshed at a certain interval (as
the CRT cycles down the screen and then returns to the top). This speed
is usually measured in Hz (cycles per second), which is a unit of frequency.
A refresh rate of 60 Hz will produce a slightly perceptible flicker of the
screen that can cause eyestrain. A rate of 72 Hz or faster will usually pro-
duce a comfortable image. Your monitor may refresh at different frequen-
cies depending on the resolution. Check your monitor specifications for the
refresh rate; this may help prevent eyestrain. If you do need to use another
driver with your external monitor, you might need to reset the driver for
the LCD to achieve optimal display quality on the LCD. Windows will
