What is Aspect Ratio?
Aspect ratio is the ratio of the image wi
dth to image height. Standard TV screens 
and older laptops are 4:3; HDTV and  most DVDs are 16:9; and widescreen 
computers are 16:10. If you are projecting  onto a screen, the size/shape of the 
screen will influence the aspect ratio you  decide to use. If you are projecting onto a 
blank wall, there are no screen size restrict ions. What you plan to project will also 
help you choose between 4:3, 16:9 or 16: 10. Many TV shows are 4:3, while most 
movies are 16:9.
If you have a 16:9 screen then you should  select an aspect 
 ratio of 16:9 for 
widescreen movies or HDTV, and Native fo r 4:3 content. If you have a 4:3 screen 
you should still use 16:9 for widescreen  movies or HDTV, but you also have the 
option of using either 4:3 (t o fill the screen) or Native (for direct pixel mapping). 
Force Wide can also be enabled to automatically resize less common aspect ratios to 
16:10.

Connecting a video device
You can connect video devices such as VCRs, DVD players, camcorders, digital 
cameras, video game consoles, HDTV receivers, and TV tuners to the projector. 
You can connect the audio directly to the projector to get sound from the built-in 
speaker, or you can bypass the projector’s audio system and connect the audio 
directly from your source to a stereo or home theater system.
You can connect the projector to most video devices that can output video. You 
cannot directly connect the coaxial cable that enters your house from a cable or 
satellite company, the signal must pass through a tuner first. Examples of tuners are 
digital cable boxes, VCRs, digital video recorders, and satellite TV boxes. 
Basically, any device that can change channels is considered a tuner.
Before connecting your projector, you should decide which aspect ratio you want to 
use. The projector’s Aspect Ratio setting is accessed through the Resize button on 
the remote or through the projector’s Basic Picture Menu. See 
page 31 for more 
information.
Video device connections
No video cables are provided with the projector. You can order cables from InFocus 
or provide your own.
Composite video connection
Plug the composite video cable’s yellow connector into the video-out connector on 
the video device. Plug the other yellow connector into the yellow Video connector 
on the projector.
If your source uses RCA connectors, connect the red audio out connector on the 
audio source to the red audio in connector on the projector and white audio out 
connector on the audio source to the white audio in connector on the projector.  
If your source uses a 3.5mm stereo connector, connect it to the 3.5mm audio in 
connector on the projector.
VGA connection
If your video device has a 15-pin VGA output, plug one end of the included 
computer cable into the VGA connector on your video source. This connector may 
be labeled “To Monitor” on the video source. Plug the computer cable into the VGA 
connector on the projector.
Component video connection
If your HD video device has component connectors, an optional Component to 
VGA adapter can be used. Plug the component cable into the video device. Plug the 
other end of the component cable into the adapter and plug the adapter into the 
VGA connector.

LiteBoard™ Wan d
The LiteBoard Wand works like a wireless mouse - but one that works in midair, not 
on your desktop. Just hold the wand in your  hand, and point it at the projected 
image to point, click and drag. The wand work s with all your software, just like a 
regular mouse.
Charging the Wand’s Battery
When the wand’s amber battery light starts to blink, its internal battery is low (if the 
battery is fully discharged,  you won’t be able to turn th e wand on by pressing its tip, 
left or right buttons).
To charge the battery, open the flap at  
 the bottom of the wand to expose the wand’s 
USB connector. Then connec t a USB cable between the wand and the USB power 
adapter, or a computer (if connecting to  a computer, make sure the computer is 
powered on). The battery light  will stay on while the battery is charging, then it will 
turn off when the battery is fully charged.
When charging is finished, you can disc onne
 ct the USB cable (or keep the cable 
connected and use the wand while it’s charging).
NOTE: 5-10 min
 utes of charging is enough for about an hour of wand use. A full 
charge will take 6-8 hours  and will allow 20-40 hours of non-stop wand use. A fully 
charged, new wand will hold a charge in standby for up to 3 weeks.
Caution : The 
 lithium battery is  only rechargeable, and is  not user serviceable or 
user replaceable.
Caution : 
Always use the included USB ca ble and power adapter (or your 
computer) to charge the wand.
How to Use the Wand
1The IN3914 projector needs to be powered on and connected to your computer.
2Connect the projector and your  computer with a USB cable.
3Connect the projector and your computer with a VGA cable.
4Make sure the wands battery is charged or charging.
5Turn on the projector and make sure its  displaying the computers screen - set  the source to VGA 1 or VGA 2 (press the 
source button on the projector or its 
remote if needed - you may need  to press it several times).
6Turn on the wand by pressing its tip, left or  right button - the wands blue status 
light will start to blink.
7Point the wand at the screen to point, click, and drag - just like a normal mouse. 
The undo button is located at the bottom th e wand. You can define this button in 
the LiteBoard Wand Menu .
NOTE: 
See LiteBoard Wand Menu below for set tings that let you fine-tune wand 
motion and clicking behavior. When you’re  done, set the wand aside and make sure 
it isn’t pointing at the screen; it will turn itself off automatically after 1 minute.
Wand Position and Avoiding Shadows
Your Location Distance from the Screen
You can use the LiteBoard Wand right up ag ainst the screen, or around the room. 
You might find that your pointing accuracy  will improve if you get closer to the 
screen. Also, avoid standi ng too far off from either side of the screen.
Avoid Shadows!
The wand wont work if its sensor is in a  shadow or if it is pointing at a shadow:
Correct (no shadow) Incorrect (shadow) 
						

							13
How to Hold the Wand
You can hold the wand the way you would hold a normal pencil or pen, or you can 
hold it like a remote control - use in wh
ichever position is most comfortable. 
NOTE: If the wand is up close to the screen, you can press its tip against the 
projection surface to click and drag. Not  recommended for use with fabric screens.
Using More than One Wand
The projector can work with more than one wand, but you can  only use one wand at 
a time. When you want to switch to a different wand: 
1Point the current wand away from the pr ojected image for at least 3 seconds.
2Press the tip, left or right button on the new wand to turn it on, and then start 
using the new wand.
NOTE: 
Settings in the projectors LiteBoar d Wand menu (see below) apply to all 
wands used with that projector.

Buttons and Wand Tip
The wands three top buttons are equivalent
 to the left, right, and scroll wheel 
buttons on a mouse. The wand s tip is also a button, and is equivalent to the left 
mouse button. 
NOTE: By defa
 ult, the Scroll Wheel  button changes wand motion between  Auto, 
Normal  and Draw . Auto switches between  Draw, Normal  and Stable  mode 
depending on the image  size and distance. Normal  makes clicking easier, but  Draw 
allows smoother motion. You can change  the Scroll Wheel button to perform other 
functions, including a standard middle  button mouse click (see LiteBoard Wand 
Menu below).
Battery Light
The amber battery light show s the status of the wands built-in battery (see below 
for battery information). The battery light will turn on while the wand is charging, 
and it will blink if the battery is  low (2-4 hours of wand use left). 
						

							14
Link Light
The blue link light shows the status of the wands wireless connection to the 
projector. The link light will blink frequently (more than once per second) when the 
wand is attempting to link to the projector; then it will blink less frequently (about 
once every 4 seconds) after the wand has linked to the projector. 
NOTE: The link light will stay off when the wand is off.
USB Connector
The wands USB connector is behind a flap on the back of the wand. The USB 
connector is only used for charging the wands battery - using the included USB 
power adapter, or a computer. 
NOTE: You can use the wand while charging the battery, but after the battery is 
charged (battery light turns off), you can unplug the USB cable and continue to use 
the wand without a cable.
Undo Button
The wands Undo button will function the same as the computers Escape, Delete, or 
Backspace buttons, or the same as a Ctrl+Z (Windows/Linux) or Cmd+Z (Mac OS) 
command, depending on which function you assign to it in the LiteBoard Wand 
menu. 
Sensor
The wands optical sensor opening is located above the wands tip. Dont block the 
sensor, and make sure it always has a clear view of the screen. 
NOTE: The sensor wont work if you point it at a shadow or away from the screen.
Reset Button
The wand has a reset button, behind a small hole on its underside. Under normal 
conditions, you should not need to reset the wand. See the Troubleshooting section 
below for more information.
Internal Radio
The wand has a built-in wireless transmitter/receiver which it uses to communicate 
with the projector.

• If the wand doesnt work at all, or it works intermittently, try one of these 
solutions:
- Press to Move may be enabled; try holding down one of the wand’s buttons 
while moving the wand.
- Press the tip, left or right button on the wand to turn it on.
- If the wands blue Link light never blinks, then the wands battery is fully dis-
charged; connect the wand to the USB power adapter or your computer.
- Make sure the wand is not pointing at a shadow and make sure its tip is not in 
a shadow.
- If the room is brightly lit, reduce the room illumination.
- If youre trying to use the computers mouse at the same time as the wand, 
point the wand away from the screen while using the mouse.
- If someone else is using a different wand with the same projector, they must 
stop using it before you can use another wand.
- Change the Link Channel value in the LiteBoard Wand menu.
- Reset the wand: push the end of a paper clip into the reset opening on the 
underside of the wand.
• If accurate clicking is difficult, try one of these solutions:
- Hold the wand steadier when clicking.
- Use the wand right up against the screen so its easier to avoid unexpected 
movements.
- Change the Motion value in the LiteBoard Wand menu.
• If it is difficult to draw or move freely because the wand wants to move in 
straight lines or draw extra lines, try changing the Motion value in the 
LiteBoard Wand menu.
• If the mouse pointer is in the wrong place on the screen, or the mouse pointers 
movement is restricted to only part of the screen, try one of these solutions:
- Make sure your projector is displaying the computers screen and not some 
other source (such as DVD, VCR, etc.). To change the source, press the Source 
button on the projector or its remote.
