If you’ve connected a 
computer and the image 
doesn’t look right or fit 
properly on the screen, press 
the 

Auto

 button on the 

remote control (or the 

Auto/Enter

 button on the 

projector’s control panel). 

This automatically resets the projector’s tracking, sync, 
resolution, and position settings. 

Auto

Also, make sure the correct 

Computer

 or 

BNC Input

 option—

such as 

Analog RGB

—has been selected in the Setting menu. 

Alternatively, you can cycle through the input settings using 
the corresponding source button (

Comp

, 

BNC

) on the remote 

control until you see your device.

If vertical stripes appear in the projected image and the 

Auto

 

button doesn’t correct the problem, hold down the 

Shift

 

button on the projector’s control panel while pressing either 
the 

Tracking +

 or the 

Tracking – 

button.

If the image appears fuzzy or flickers and the 

Auto

 button 

doesn’t correct the problem, hold down the 

Shift 

button while 

pressing either the 

Sync +

 or 

Sync – 

button.

Note: Also make sure you have selected the correct Computer or 
BNC Input option in the Setting menu for your computer. See the 
User’s Guide for more information.

Even if you don’t have a screen, you can project images onto 
surfaces like blackboards and colored walls without loss of 
image color. Your projector has a sensor that measures the 
conditions of the projection surface and automatically adjusts 
the colors and shading of your image. For example, if you’re 
projecting onto a surface near a window, your image appears 
clear and well-defined rather than faint.

Press the 

Wall Shot

 button on 

either the remote control or the 
projector’s control panel while 
projecting an image.

Wall Shot’s status appears in 
the upper right corner of your 
screen. Then you see a sequence 
of colors flash for approximately 
five seconds while the sensor 
measures the conditions of the 
projection surface and adjusts 
the image. 

Wall Shot

When you turn off the projector, it stores the correction values 
obtained by the last Wall Shot measurements. This is useful if 
you’re projecting against the same surface and under the same 
conditions. To retrieve these corrections, just press the 

Wall 

Shot

 button again while projecting an image.

Follow these steps to adjust the correction values if you’re 
projecting on a new surface or in a new location:

1. Press the 

Wall Shot

 button on the remote control or 

projector while you’re projecting an image. Wait for the 
Wall Shot status screen.

2. Press the 

Wall Shot

 button until you see 

Wall Shot 

Readjustment 

on the status screen. 

You see a sequence of colors flash for about five seconds as 
the projector adjusts the color correction values for the new 
projection surface.
