The Image Shift menu allows you to precisely center the image on the screen. (These controls are available only with a 480i source signal.)

Horizontal: This control moves the image right or left within the area of available pixels.

Vertical: This option moves the image up or down within the area of available pixels.

NOTES:

1.To adjust the image position with a 480p or higher- resolution source, use the PC & HD Adjust controls in the Option menu, described on page 38.

2.The values shown represent where the approximate center of the image lies in relation to the total number of pixels available horizontally or vertically. This varies widely according to the signal; watch the image while adjusting.

Video Black Level

>0 IRE

7.5 IRE

The Amplitude Adjust menu allows you to fine-tune the curently-selected image aspect ratio by stretching it horizontally or vertically, in small increments. This can be useful if your projector is equipped with an anamorphic lens.

The Horizontal control adjusts the image width while keeping the height constant. Similarly, the Vertical control adjusts the image height while keeping the width constant.

This control compensates for incoming elevated black levels present in certain video signals, and ensures that blacks in the display are neither “crushed” (where dark grays appear black) nor excessively elevated (where blacks appear dark gray). By default, the projector automatically determines the best setting according to the type of incoming video signal:

•0 IRE – Used for DVD output with “enhanced black,” SECAM, most PAL standards and Japanese NTSC.

•7.5 IRE – Used for most NTSC video signals.

For some types of video, you may want to override the setting. Generally, if black appears crushed when brightness = 30, choose “0 IRE”. If black appears excessively elevated, use “7.5 IRE”.

Lamp Power 250 W

Select Lamp Power from the Set Up Menu to adjust the lamp output level. You can choose to run the lamp as bright as possible (250W; this is the default setting) or you can choose the lower (200W) setting. Generally, lower lamp output can prolong the life of the lamp, but decreases brightness.
