Image Options

Keystone

This feature corrects the keystone (trapezoidal) distortion to make

the top of the screen longer or shorter to be the same as the bottom.

Use the





buttons on the slide bar to correct the keystone

(trapezoidal) distortion.

Keystone distortion

Normal

NOTE: The maximum keystone angle that can be corrected is 40 degrees up-

ward and 20 degrees downward with the projector placed horizontally on the

ground plane.

Depending on the type of graphics being used, the picture may get

blurred or keystone correction may not be possible when excessive

keystone correction is used.

The idea is, the closer you are to native resolution, the better image

you will see.

Lamp Mode

You can select the aspect ratio for input signal and display area re-

spectively.

Select the appropriate aspect ratio using the Select





NOTE: When “Resolution” is set to “Native”(See page E-34) and/or “S-Video

Mode Select” is set to “S2”(See page E-38), this feature is not available, and

the stored settings and adjustments are invalid.

The screen size (width-to-height) is set for input signal and display area re-

spectively.

Normal and Eco modes. The lamp life can be extended up to 2500

hours by using the Eco mode.

NOTE: If you have selected the Eco mode, the lamp lights in Normal mode for 3

NOTE: The lower the Noise Reduction level, the better the image quality by way

of higher video bandwidth.
