Displaying From a PC Laptop
If you see the "No Signal" message when you display from a PC laptop, you need to set up the laptop to
display on an external monitor.
1. Hold down the laptop's Fn key and press the key labelled with a monitor icon or CRT/LCD. (See
your laptop manual for details.) Wait a few seconds for an image to appear.
2. To display on both the laptop's monitor and the projector, try pressing the same keys again.
3. If the same image is not displayed by the laptop and projector, check the Windows Display utility to
make sure the external monitor port is enabled and extended desktop mode is disabled. (See your
computer or Windows manual for instructions.)
4. If necessary, check your video card settings and set the multiple display option to Mirror or
