Display Formatting

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

Command Name Description
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.

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