Setting Up
●If the selected video image is not displayed after the projector is turned on and the correct
video source has been selected, please check that the video source device is turned on and
operating correctly. Also check that the signal cables have been connected correctly.
●Many laptops do not turn on their external video ports when connected to a projector.
Usually a key combination like Fn + F3 or CRT/LCD key turns the external display on /
off. Locate a function key labeled CRT/LCD or a function key with a monitor symbol on
the laptop. Press Fn and the labeled function key simultaneously. Refer to your laptop‟s
documentation to discover your laptop‟s key combination.
