scanned appears in the upper left corner of the screen. If the projector doesn't detect a
valid signal, the message 'No Signal' will continue to be displayed until an input
signal is found.
You can also press SOURCE on the projector or remote control to select your desired
input signal. See "Switching input signal" on page 24 for details.
If the frequency/resolution of the input signal exceeds the projector's operating range, you will
see the message 'Out of Range' displayed on a blank screen. Please change to an input signal
which is compatible with the projector's resolution or set the input signal to a lower setting.
See "Timing chart" on page 52 for details.
