Operations
Basic operations (Continued)
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 AUTO SET button.
The icon will appear during processing.
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.53 , p.54 .
If auto setting fails adjustment, adjust manually with the
Position adjustment
menu p.37 .
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
1
Press the KEYSTONE button.
2 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.
The keystone correction settings are memorized after the power has been turned off.
Therefore, it is recommended that you set [
Auto keystone ] to [ Off ], if the case is that
the projector placement angle against the screen remains unchanged and you do not
wish to change the keystone adjustment that you set.
Some adjustments using both digital zoom and keystone correction while displaying
an input image with a 16:9 aspect ratio, may affect displaying the menu properly. In
such a case, reset either digital zoom or keystone correction to use the menu.

Precautions
Lamp characteristics may rarely cause the brightness to fluctuate slightly.
DLP
®
chip 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.53 , 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.
