7.7.1 Digital Zoom

Digital Zoom
This function will zoom the picture digitally. When zooming in, the center of the image will increase in size. This
means that the outer part of the picture will be outside the projectors picture frame. When zooming out, the
result is that the picture will be smaller than the projectors picture frame. The area outside the rendered picture
will then be black.
See the illustrations below. The red lines in the figures represent the DMD outline.
Enter the menu showed above and toggle the Digital zoom switch. Select the slider according to the
instructions in the menu and move it to the desired zoom level.
The numbers on the right side of the menu represent the "new" resolution of the picture (assuming that the
whole picture should be visible) in pixels. The aspect ratio will not be affected by the zoom function.
This function can also be used in combination with digital shift.
