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 labeledfunction key simultaneously. Refer to your laptop's
documentation to discover your laptop's key combination.
