Blanking a picture-in-picture (PIP) image resembles zoom. For example, left Blanking zooms
the right side of the PIP image; Right Blanking zooms the left side. There are no black bars.

2. To specify a specific active input window size, adjust one or more Blank settings.

For example, if you have blanked (cropped) 100 pixels from both the left and right edges of an
incoming source of 1400 x 1050, the remaining active input window is reduced to 1200 x
1050.

Correcting a keystoned image

Keystone is typically caused by tilting the projector in relation to the screen so the lens surface and

screen are no longer parallel to each other.
Vertical keystone is used to correct a keystoned image shape in which the top and bottom borders of
the image are unequal in length, and both sides of the image are inclined toward the top or bottom
edge.

Horizontal keystone is used to correct a keystoned image shape in which the left and right borders of
the image are unequal in length, and the top and bottom are slanted to one of the sides.
