Interactive Whiteboard Description
1), When the projected image is in the form of a keystone, the
image is distorted and thus should be adjusted.
2), When a vertical keystone is projected, you can use the special adjustment button or elevate the projector to make an adjustment (for more information, refer to the projector manuals).
3), When a horizontal keystone is formed, you can adjust the location of the projector to the center of the whiteboard to achieve front projection.
4), You must make a few final adjustments to the projector to ensure a focused image that fits within the interactive whiteboard frame at the top and bottom, with a margin of approximately 3/8" on both the right and left sides.
5), NOTE: The 3/8" margin described above is an optimal measurement. Alignment can vary: in some instances, the image can fill the entire screen; in others, the margin can be greater than 3/8", but be perfectly satisfactory as long as it’s even on all sides.
6), You can fix many projector-related problems right at the projector itself, just by shifting the projector to the right or left, tilting it or using the zoom lens to sharpen the focus or expand and contract the image. You can also solve many keystone problems by raising or lowering the front or back of the projector until the sides of the image are parallel to the screen frame.
