Display Formatting

The controller provides several functions related to formatting the displayed image that are summarized in the table below.

Command NameDescription
Image Flip

Flip image in Horizontal and/or Vertical direction.

Keystone Angles

Controller adjust the display image automatically as per the 3D keystone settings where it takes three co-ordinates Pitch, Yaw, Roll; for 1D keystone user can set the Yaw and Roll to 0. This feature is useful when projecting on surfaces/screens non-orthogonal to projector.

Keysone Corners Configures the 2D Keystone correction when the corners of the corrected image are known.
Display Image Size

Define a custom displayed image size.

Manual Warp TableSend warp points to be used for image warping.
Manual Warp Control PointsDefine the width and height of two dimensional point array sent using Manual Warp Table command. This command also enables/disables manual warping feature.
