Basic operations (Continued)

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.

This function automatically adjusts the projector settings such as 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 supported by the projector p.94 , p.95 .

If auto setting fails adjustment, adjust manually with [Position] in the Position adjustment menu p.39 .

The keystone distortion will be corrected automatically based on the projector’s placement angle.

Adjusting Keystone distortion [Manual]

1Press the KEYSTONE button.

2Use 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.
