Adjusting the Projected Image
If your projector isn’t installed in a fixed location, you can correct many image
problems by shifting your projector or adjusting its zoom lens. Optimally, you should
have a margin of approximately 3/8" (1 cm) on both the right and left sides of the
screen. You can then adjust the zoom lens to display a focused image.
NOTES
• Don’t adjust the image size and geometry based on your projector’s splash
screen. The splash screen image is much smaller than the computer’s
projected image. Before you adjust the projected image, make sure that you
set the computer’s resolution and refresh rate. See Configuring Your
Computer Settings on page 24.
• Complete the following steps only as required.
To adjust the
projected image
1. If the left and right edges of the projected image aren’t parallel, raise or lower your
projector at the front or back until the edges are parallel.
2. If the top and bottom edges aren’t parallel, turn the projector slowly until the edges
are parallel.
3. Further adjust your projector using small, slow movements until you’re satisfied
with the projected image.
– Correct the image’s horizontal and vertical position by adjusting the height
and position of the projector platform or stand.
– Adjust the image laterally by sliding the projector to the left or right.
– Adjust the image size by moving the projector forward or backward
to increase or reduce the image size, until it correctly fills the screen.
4. Make fine adjustments to the image level and size according to your projector
manufacturer’s instructions.
5. Create a clear image by adjusting your projector’s focus function.
