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 VGA cable between the projector and the computer before turning on the computer. 
There are some notebook PCs, which do not output signal unless there is a projector or monitor connected 
fi r s t .
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. See page 
53 or go to next step.
•  Enabling the computer’s external display.
  Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projec-
tor.  When using a PC compatible laptop, a combination of function keys will enable/disable the external dis-
play.  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 more details, refer to your computer’s owner’s manual.
•  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 pre-
vious step. Refer to your computer’s documentation for detailed information.
•  Image displayed is incorrect when using a Macintosh
  When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projec-
tor) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
  For setting display modes other than those supported by your Macintosh 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” fi xed mode and then restart your Macintosh. After that, restore the DIP switches to a dis-
playable mode and then restart the Macintosh again.
NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini 
D-Sub 15-pin connector.
•  Mirroring on a PowerBook
*  When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring” 
is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.
•  Folders or icons are hidden on the Macintosh screen
  Folders or icons may not be seen on the screen. Should this happen, select [View] 
→ [Arrange] from the Apple 
menu and arrange icons.

*
1  Effective pixels are more than 99.99%.
*2  What is HDCP/HDCP technology?
HDCP is an acronym for High-bandwidth Digital Content Protection. High bandwidth Digital Content Protection 
(HDCP) is a system for preventing illegal copying of video data sent over a Digital Visual Interface (DVI).
If you are unable to view material via the DVI input, this does not necessarily mean the LV-7265 projector is not 
functioning properly. With the implementation of HDCP, there may be cases in which certain content is protected 
with HDCP and might not be displayed due to the decision/intention of the HDCP community (Digital Content 
Protection, LLC).
