Using Handy Features; Using Auto Setting (For Computer Input Only); Correcting The Keystone Distortion - Toshiba TLP-X100U Owner's Manual

Basic operations (Continued)
Precautions
• Lamp characteristics may rarely cause the brightness to fluctuate slightly.
• The LCD panel is made using extremely advanced 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 technology and are not malfunctions.
Notes
• 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.)
• Although this projector supports a wide range of RGB signals
not supported by this projector (XGA for X100, WXGA for WX100) will be expanded
or shrunk, which will affect image quality slightly. To view high-quality images, set the
computer's external output to XGA for X100 and WXGA for WX100.
• 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 computer's owner's manual.
• If no signal is being input from the connected equipment or signal input is stopped while
projecting, the "No signal" message will appear.
• If a signal not supported by the projector is input, the "Unsupported signal" message
will appear.
• If an unavailable operation button is pressed, the
(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.
• In order to extend the lifetime of the LCD panel, always turn off the power when not in
use, and make sure that the lamp is off. Keeping the lamp off is also very effective at
saving 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 , and replace it periodically. Contact the store where you

purchased your projector, or your local Service Station for replacement air filters.

Using handy features

Using auto setting (For computer input only)


This function automatically sets up the projector to the optimum state. It
sets up sampling phase, frequency and screen position, for each type
of the input signal by using simple operations.
Press the remote control's AUTO SET button.
The icon will appear during processing.
You can set as well by selecting [Auto setting] in the Image
adjustment menu .

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
• If auto setting fails adjustment, adjust manually with [Position] in the Image
adjustment menu
p.35 .

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
• The keystone distortion will be corrected automatically based on the projector's
placement angle.
Adjusting Keystone distortion Manually
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.
