Horiz. Shift, Horiz. Offset and Vertical Shift

This function enables horizontal or vertical shifting of the image. If the image contains undesired
lines like closed caption it is possible to move this in the blanking area. Distortion of the picture
during adjustments can occur.

3.9

Horiz. Zoom and Vertical Zoom

The MGVC 1280 offers a certain percentage of zoom both in vertical and horizontal direction.
Together with the shift function it is a powerful tool to zoom in the active picture area for
magnification.
The higher the zoom factor the lower the video image quality.

3.10

Input Size and Shift

The 

Horizontal Size

 and 

Vertical Size

 adjustments allow the increase of active pixels.

Digital projectors or displays sometimes do show black bars at the borders of their panel area.These
unused panel area may then be filled increasing the active size of the image.

Horizontal Shift

 and 

Vertical Shift

 allow the positioning of the active area on the physical panel

device. Do not forget to  STORE  the settings after making adjustments.
Do not use the Size and Shift functions with CRT projectors because the projector itself is offering
these adjustments without affecting the image sharpness.
