If there is no picture, or the picture is not displayed correctly.

• Power on process for the projector and the PC. Be sure to connect the projector and notebook PC while the
projector is in standby mode and before turning on the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on unless connected to the projector before
being powered up.
NOTE:
• You can check the horizontal frequency of the current signal in the projector's menu under Information. If it reads "0kHz", this means
there is no signal being output from the computer.
• Enabling the computer's external display.
Displaying an image on the notebook PC's screen does not necessarily mean it outputs a signalto the projector.
When using a PC compatible laptop, a combination of function keys will enable/ disable the external display.
Usually, the combination of the "Fn" key along with one of the 12 function keys gets the external display to come
on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle
through external display selections.
• Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC's LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the previ-
ous step. Refer to your computer's documentation for detailed information.
• Image displayed is incorrect when using a Mac
When using a Mac with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector)
according to your resolution. After setting, restart your Mac for the changes to take affect.
For setting display modes other than those supported by your Mac and the projector, changing the DIP switch
on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP switch
to the 13" fixed mode and then restart your Mac. After that, restore the DIP switches to a displayable mode and
then restart the Mac again.
