Transport Delay de
fi nition
During this delay all image information is gathered and processed by the projector.
A Transport Delay set to the maximum. value 1023, corresponds with a delay of 16 ms.
What can be done with the Transport Delay ?
The fi rst image data the projector receives from the Image Generator is the start of the fi rst active line. However when a top side
bow pre-distortion is used, the fi rst image data the projector needs is the image information that is halfway that fi rst active line, to
gather all this information before projecting it on the screen, an adjustable Transport Delay is applied on the received image data.

Transport Delay basic principle
The Transport delay can be adjusted manually or can be set automatically.
A short Transport delay has the advantage of creating small delay with respect to the source, whereas a large delay is needed in
case of extremely distorted images (extremely curved screens).
A delay set too short may introduce ’clipping’ phenomenons in the image.
How to set Transport Delay to manual or automatic ?
1. Start up the Geometry Edit menu
2. Push the cursor key ↑ or ↓ to highlight Transport Delay... and press ENTER to select.
