Portable and Laptop Activation Chart

Many laptop computers do not automatically turn on their exter-
nal video port when a secondary display device such as a projec-
tor 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 com-
puter’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 doc-

umentation for details on your spe-

cific model.
