Geometry Correction - Christie DHD700-GS User Manual

Geometry correction

Geometry correction provides two ways for warping control:
• PC Mode off—User can do simple horizontal and vertical keystone, pincushion, and 4-corner
control by using the on-screen display.
• PC Mode on—User can do arbitrary warping or blending control by using the PC APP provided
separately.
The following table provides information about the geometry correction feature compatibility:

Keystone
Pincushion
Horz Keystone
Adjust the keystone horizontally to make the image more square. Horz Keystone corrects 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. Use Horz Keystone with horizontally on-axis
applications. For horizontally offset applications, use 4-Corner correction using the OSD control or
the PC App provided separately.
B
Vert Keystone
Adjust the keystone vertically to make the image more square. Vert Keystone corrects 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. Use with vertically on-axis applications. For vertically offset
images, use 4-Corner correction using the OSD control or the PC App provided separately.
