* Visualization uses the current screen size and Projection Distance (m) field above. If no distance is entered, the Wide-zoom throw distance for the selected lens is used as an estimate.
* Click and drag the projected image (yellow) to adjust lens shift, within the lens's shift range.
* In Side/Top View, click and drag the projector itself to change the projection distance — image size, brightness, and contrast update to match.
