If the image still isn’t large enough, you may need to move the 
projector farther away from the screen. You can also use the 
E-Zoom 
button on the remote control to zoom in on a portion of the image. 
See page 50 for instructions. 
Resizing the Image
If only part of your computer screen is displayed, your computer may 
be set for a higher resolution than the projector’s “native” display: 
1024 
´ 768 pixels (PowerLite 8100i) or 1280 
´ 1024 (PowerLite 
9100i). You can resize the image to fit the resolution of your 
projector.
nPress the Resize button on the remote control or the control 
panel. The screen image is automatically compressed.
nContinue pressing the Resize button to pan around the screen in 
the original resolution. 
If you’re projecting from video equipment, pressing the 
Resize 
button switches the aspect ratio between 4:3 and 16:9. If you have 
zoomed in on your image, you can also use the 
Resize button to 
switch it back to the original display size.

the projected image. Press the knob to make it pop out; then turn it 
clockwise or counterclockwise to move the lens up or down. When 
you’re finished, press the knob back in.
Using the Projector’s Feet
If the image is too low, you can extend the projector’s feet to raise the 
lens. Follow these steps:

2. Raise or lower the projector until the image is positioned where 
you want it.
3. Release the levers to lock the feet in the new position and set the 
projector down gently.
4. To fine-tune the height of the projector, turn the feet. Turn them 
clockwise to raise the projector and counterclockwise to lower it.
If the image shape becomes distorted after you adjust the height, see 
the following section.
Adjusting the Image Shape
If the projected image isn’t square or has a “keystone” shape, do one or 
more of the following:
nIf your image looks like   or  , you’ve placed the 
projector off to one side of the screen, at an angle. Move it directly 
in front of the center of the screen, facing the screen squarely.
nIf your image looks like   or  , press the + or — side of 
the 
Keystone button to correct the shape of the image. After 
correction, your image will be slightly smaller.
You can also perform electronic keystone correction using the 
projector’s Setting menu. See page 69.
Adjusting the Tracking and Synchronization
If you’re projecting from a computer and you notice vertical stripes or 
the image is flickering or noisy, you can increase the clarity by pressing 
the   button on the control panel or the 
Auto button on the remote 
control. This resets the projector’s tracking, sync, and position 
settings. If necessary, you can also correct the image manually using 
the 
Tracking and Sync buttons on the control panel.

almost anywhere in the room—up to 32 feet away. You can use it to 
turn the projector on and off, zoom the image, and display the 
projector’s menus, for example.
If you have connected the mouse cable (as described in Chapter 1), 
you can also use the remote control as a wireless mouse to run your 
presentation.
Before you can use the remote control, you need to install the

Using the Remote Control as a Wireless Mouse
Using the remote control as a wireless mouse gives you more 
flexibility; you don’t need to stay near your computer or the projector. 
First make sure you have connected the mouse cable between the 
projector and your computer with the main cable, as described in 
Chapter 1.
Note that your computer’s mouse is disabled when you connect the 
projector’s mouse cable. If you have a laptop, you cannot use an 
external mouse; however, you may still be able to use the computer’s 
built-in mouse pointer.
