Precautions
Lamp characteristics may rarely cause the brightness to fluctuate slightly.
The LCD panel is manufactured using high precision technology. There may be black
spots (pixels that do not light) or bright spots (pixels that are constantly lit) on the
panel. These are intrinsic characteristics of the manufacturing technology and are not
malfunctions.
Notes
A lamp is a consumable item. If used for extended periods, images will appear dark, and
the lamp could burn out. This is characteristic of a lamp, and is not malfunction. The
lifetime of the lamp depends on conditions of use.
Although this projector supports a wide range of RGB signals
p.66
, any resolutions not
supported by this projector (XGA) will be expanded or shrunk, which will slightly affect
image quality. To view high-quality images, set the computer’s external output to XGA.
With some computer models having LCD or similar displays, displaying images
simultaneously on the projector and the monitor’s display may prevent the images from
displaying properly. If this happens, turn off the computer’s LCD display. For information
on how to turn off the LCD display, see the computer’s owner’s manual.
A “No signal” message will appear if no signal is being input from the connected
equipment or if signal input is stopped while projecting.
If a signal not supported by the projector is input, the “Unsupported signal” message
will appear.
If an unavailable operation button is pressed, the
icon will appear with a beep sound
(if the beep sound is set to [On]).
Moving pictures played back on computers using DVD software may appear unnatural
when projected with this projector. However, it is not a malfunction of the projector.

LCD Panels
LCD panels wear out. In order to prolong the lifetime of your LCD panel, take the
following precautions;
• To extend the lifetime of the LCD panel, always turn off the power when it is not in use,
and make sure that the lamp is off. Keeping the lamp off will also save electricity.
• If the air filter becomes dirty and clogged, the projector’s internal temperature will
rise, shortening the lifetime of the LCD panel and causing malfunctions. Clean the air
filter from time to time
p.60
, and replace it periodically. Contact the store where you
purchased your projector, or your local Service Station for air filter replacement.
Using handy features
Using auto setting (For computer input only)
This function automatically sets up the projector to the optimum state.
It sets up the sampling phase, frequency and screen position, etc., for
each type of input signal through a simple operation.
Press the remote control’s AUTO SET button.
The
icon will appear during processing.
You can also set it by selecting [Auto setting] in the Image
adjustment menu
p.35
.
Notes
The image may not be projected or auto adjustment/setting may not be performed
correctly for input signals other than those supported by the projector
p.66
,
p.67
.
If auto setting fails adjustment, adjust it manually with [Position] in the Image
adjustment menu
p.35
.
Correcting the keystone distortion
When the projector placement angle toward the screen is changed while projecting the
image, the picture will undergo keystone (trapezoidal) distortion.
This projector is capable of automatically correcting this keystone distortion based on
the projector’s placement angle.
Before correction
After correction
Adjusting Keystone distortion Manually
Use the
buttons for manual keystone
adjustment.
Notes
Depending on the amount of keystone adjustment
needed and the image content, some information
may be lost, or the picture quality may suffer.
Even if [Auto keystone] is set to [On], keystone
distortion can be adjusted manually. Note that if
you change the position or angle of the projector,
automatic keystone correction will be performed again.
When [Auto keystone] is set to [On], the automatic keystone correction will be
performed each time the power is turned on.
Since keystone correction settings are memorized after the power has been turned
off, it is recommended that you first set [Auto keystone] to [Off]. Then if the projector
placement angle against the screen remains unchanged, the keystone adjustment
will also remain unchanged.
