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.
Hold down the laptop's Fn key
and press the key labeled with a monitor icon or CRT/LCD. (See your laptop manual for details.)
Wait a few seconds for an image to appear. To display on both the
laptop's monitor and the projector, try pressing the same keys
again.
Note: On Windows 7
or later, hold down the Windows key and press P at the same time, then click Duplicate.
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.)
If necessary, check your video card settings and set the
multiple display option to Clone,
Mirror, or Duplicate.
