Epson Powerlite 9100i Multimedia Projector Users Guide

							Using the Projector45
Rotate the zoom ring to enlarge or reduce the image.
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 8200i) or 1280 × 1024 (PowerLite 
9100i). You can resize the image to fit the resolution of your 
projector.

Press the Resize button on the remote control or the control 
panel. The screen image is automatically compressed.

Continue 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.

Adjusting the Height of the Image
You can adjust the height of the image using the lens shift knob on the 
side of the projector and the projector’s feet.
Using the Lens Shift Knob
Use the lens shift knob on the side of the projector to raise or lower 
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:
1. Stand behind the projector and hold up the front while you 
squeeze the blue foot release levers against the projector. This 
unlocks the feet.

2. Raise or lower the projector until the image is 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:

If your image looks like   or  , you’ve placed the 
proje ctor off to one side of the scree n, at an an gle. M ove it directly 
in front of the center of the screen, facing the screen squarely.

If 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.

The remote control lets you access your projector’s features from 
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
When you use the remote control as a wireless mouse, 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.

Controlling the Projector
While giving your presentation, you may want to switch between 
video sources, adjust the volume, pause the action or sound, or display 
a picture within your current video display. Make sure you have set up 
your projector and connected your audio or video source as described 
in Chapter 1.
Selecting Your Video Source
If the projector is connected to more than one computer and/or video 
source, you can use the buttons on the remote control or the control 
panel to switch between the different sources. 
On the control panel, press the 
Computer button to switch between 
the computer sources and press the 
Video button to switch between 
standard (composite) video, S-Video, and component video (BNC). 
On the remote control:

Press the Comp1 button to select the Computer 1 source. 

Press the Video button to switch between a standard composite 
video source and an S-Video source. 

Press the Comp2/YCbCr to select the Computer 2 or 
component video source.
After you select a source, the screen goes dark for a moment 
before the image appears.

volume of your video or computer sounds. 

To increase the volume, press on the right (+) side of the Volume 
button.

To turn off the picture, press the A/V Mute button. The screen 
goes dark.

To turn the image back on, press the button again.
You can also assign a user logo or image to the 
A/V Mute button so it 
displays on the screen whenever you press the 
A/V Mute button. See 
“Creating a Screen Logo or Image” on page 72.
Displaying Picture-in-Picture Video
You can open a small video window on your computer image, and 
view a video at the same time as your computer presentation. Make 
sure you have connected your VCR or other video source as described 
in Chapter 1.
1. Press the 
P in P button on the remote control. The screen may go 
dark for a moment, and then your video image appears in a small 
window on the screen. A menu appears in the lower left corner of 
the screen.

Enter button (or grasp it between your 
thumb and finger) to move the video window on the screen.

slides or call attention to your most important points. Four types of 
drawing tools (and an Erase function) are available:

Arrow or cursor stamp (button 1)

Box (button 2)

Spotlight (button 3)

Bar (button 4)

Erase (button 5)
You can select different drawing effects through the Effect menu.
