Appendix C
Portable and Laptop Activation Chart
Many laptop computers do not automatically turn on
their external video port when a secondary display device
such as a projector is connected. Activation commands
for some laptop computers are listed in the following
table. (If your computer is not listed or the given
command does not work, refer to the computer’s
documentation for the appropriate command.) On some
laptops, the activation function key is labeled with an
icon, for example or the text CRT/LCD.
Note: Often, pressing the key commands once activates
the external video port, pressing it again activates
both the external and internal ports, and pressing it
a third time activates the internal port. Refer to
your computer’s documentation for details on your
specific model.
