Sharp QA1150 Operation Manual page 16

If both a computer and a video signal are connected to the QA-1150 simultaneously,
pressing the PC/VIDEO button on the remote contro] unit switches between the computer
video output and the composite video signal.
NOTES
To display NTSC or PAL on the QA-1150, the video signal input must meet the
following requirements. If it does not, proper display will not be obtained.
(1) It must be a composite video signal complying with system M (NTSC) or systems
B, G, H and I (PAL).
(2) The signal level must be 1.0 V peak-to-peak.
(3) The output impedance must be 75 Q.
With PAL composite video signals, about 10% is cut from the top, bottom, and sides
of the display area. The TINT knob does not work with PAL composite video signals.
7) External monitor connection
Connect a computer monitor to the external monitor output connector. The image appeals
simultaneously on the external monitor and QA-1150.

NOTES
When using the QA-1150 together with an external VGA monitor, connect the
monitor using the cable supplied with the monitor. When using the QA-1150 together
with a Macintosh monitor, connect it using the external Macintosh monitor cable that
is supplied with the QA-1150. Before using any other type of monitor, carefully
check the monitor's interface specifications and make sure that they match tee
specifications of the QA-1150's interface.
The external monitor output connector will only display the computer input signal. It
will not display the composite video input signal. To split the composite video signal,
use a video distribution amplifier. This is available from your local dealer.
