Operations
Notes
Note that lamp characteristics may rarely cause the brightness to fluctuate slightly.
A lamp is 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.)
The DLP
®
chip is made using extremely advanced technology, but there may be black
spots (pixels that do not light) or bright spots (pixels that are constantly lit) on the panel.
Please note that these are not malfunctions.
Although this projector supports a wide range of RGB signals
p.94
, any resolutions not
supported by this projector (XGA) will be expanded or shrunk, which will affect image
quality slightly. To view high-quality images, it is recommended that the computer’s
external output should be set to XGA resolution.
With some models of computer having LCD displays or the like, 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 owner’s manual of your computer.
If no signal is being input from the connected equipment or signal input is stopped while
projecting, the “No signal” will appear.
If a signal not supported by the projector is input, the “Unsupport signal” will appear.
If an unavailable operation button is pressed, the
icon will appear.
Basic operations (Continued)
Using handy features
Using auto setting (Only for input from computer)

sampling phase, frequency, screen position, and clamp pulse for each
type of the input signal by using simple operations.
Press the remote control’s AUTO SET button.
For computer input, 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

Correcting the keystone distortion
When the projector placement angle against the screen
is changed while projecting the image, the picture will
undergo keystone (trapezoidal) distortion.
This projector is capable of correcting this keystone
distortion.
Before correction
After correction
The keystone distortion will be corrected automatically based on the projector’s
placement angle.
Adjusting Keystone distortion [Manual]
1
Press the KEYSTONE button.
2
Use the buttons for keystone adjustment.
Notes
Depending on the amount of keystone adjustment and the content of images, 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.
