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 § or © buttons on the slide bar to correct the keystone (trapezoidal) distortion.

NOTE: The maximum keystone angle that can be corrected is 45 degrees upward and 15 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.

Color Temperature

This feature adjusts the color temperature using the slide bar.

Move the slide bar to the right to increase the color temperature for a bluish image; to the left to decrease it for a reddish image.

Gamma Correction (not available for PC Card Viewer)

Use the § or © button to choose "Normal" when in a lighted room and "Natural 1&2" when in a darkened room. "Natural 1" for better flesh tone; "Natural 2" for true reproduction of middle tones.

Each mode is recommended for :

Normal ....... For the regular picture

Natural 1 ..... For true color reproduction of natural tones

Natural 2 ..... For dark portions of a picture
