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. (→ page
• 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 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 previous 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.
NOTE:
• A Video Adapter cable manufactured by Apple Inc. is needed for a MacBook which does not have a mini D-Sub 15-pin terminal.
• Mirroring on a MacBook
* When using the projector with a MacBook, output may not be set to the display resolution of
the projector unless "mirroring" is off on your MacBook. Refer to owner's manual supplied with
your Mac computer for mirroring.
• Folders or icons are hidden on the Mac screen
Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange]
from the Apple menu and arrange icons.
