If Images Of A Parsonal Computer Are Not Projected - NEC DT100 User Manual

■ If images of a personal computer are not projected
Check the following if images of a personal computer are not projected, or projected incorrectly.
● If images are not projected
If the external output signals from a personal computer are not input to DT100, "No PC
signal" appears on the DT100 display. Check the following if "No PC signal" appears.
1
Restart the computer.
The connection of DT100 may not be recognized by the personal computer, if DT100 is
connected after the PC is started up. If the connection is not recognized, images are not
projected because no external output signals from the PC are output.
2
Check the functions of the personal computer.
Some notebook PCs require a special operation to output the signals from the external
output terminal. The external output signals may not be output from the notebook PC
unless the operation is performed.
Refer to the manuals of your notebook PC for the information about how to output signals
from the external output terminal.
Procedure example
• In the case of IBM PC/AT
Press Fn key and one of the keys F1 - F12 . (Procedure may vary from models
to models.)

● Images are not projected correctly though they are displayed normally
on the notebook PC.
1
Check the function of the notebook PC.
There is a possibility that images are not projected correctly even through the images are
displayed correctly on the LCD of the notebook PC. When images are displayed on two or
more devices at the same time (e.g. images on the LCD and the signals are output to
other devices at the same time), the input signals are outside the scanning frequency
range of DT100 because of the restrictions on the notebook PC.
In this case, the correct images cannot be obtained even by the adjustment of DT100.
Terminating the display on the LCD, so that only the external output signals are output,
may project images correctly on DT100. Refer to the manuals of your notebook PC for
details.
