Focus

The Focus function is used to adjust the electrical focus of the combined red, green, and blue color components.

To adjust focus, select Focus from the Picture menu then use and until the center of the display appears the sharpest. If the displayed image cannot be adequately focused, a service adjustment to the electrical focus may be required or an optical focus adjustment is necessary. Refer to the section 2.8, Optical Alignment for optical focus instructions.

Sync (Fast/Slow)

The Sync function is used to minimize horizontal jittering, “flag waving” or tearing at the top of the display image. This effect sometimes occurs when the source is a VCR or video signal. The function changes the synchronization mode of the projector from fast to slow, or slow to fast.

To toggle between fast and slow sync, select item 5 from the Picture menu. Item 5 indicates the current synchronization mode.

Blanking (Top/Bottom/Left/Right)

The Blanking selection item is used to hide or blank out unwanted informa- tion or noise at the top, bottom, left, or right of the display image. Blanking adjustments may be required when the source is a VCR or video signal.

To adjust blanking, select Blanking from the Picture menu. From the Blanking menu, select item 1, 2, 3 or 4 to adjust the amount of blanking at the top, bottom, left, or right of the display (respectively). A blanking slidebar is displayed for each adjustment. A 0% level on the slidebar indicates no blanking. For top and bottom adjustments, use and to adjust the amount of blanking. For left and right adjustments,

use and to adjust the amount of blanking. After completing each adjustment, press ENTER to return to the Blanking menu, or press EXIT to return to the picture.

Auto Clamp (On/Off)

The Auto Clamp function is used to turn automatic signal clamping on or off. For most input signals, auto clamp should be on. However, if one or more of the red, green, or blue color components is abnormally bright, turn auto clamp off. An abnormally bright color component can occur if the input signal contains more than one sync type (e.g., both sync on green, and composite sync). If you are using a composite video source with ASR and are connected to an RGB interface, turn the Auto Clamp off.

To toggle auto clamp on or off, select item 7 from the Picture menu. Item 7 indicates the current Auto Clamp setting.
