5. Select Open Folder on the drop-down menu. When the folder 
opens, you see another folder with your manufacturer’s name.
6. Position the cursor on the folder and press 
Enter. Then select 
Open Folder. 
You see your image files when the folder opens.
7. Position the cursor on the image file you want to project and press 
Enter. Then select View Image.
The image is projected on the screen. If you want, you can press 
different sides of the  button to rotate the image while you’re 
viewing it.
To end projection, press the 
ESC button on the remote control, then 
select 
Exit and press Enter.
note
Make sure your camera 
shows up on your desktop as 
a drive letter. If it does, it is 
probably a USB mounted 
device and will work with 
the projector software. The 
EasyMP software does not 
support TWAIN-compliant 
digital caneras.
If your camera’s memory 
card is supported by the 
projector, you can insert it 
into the projector’s card slot
and project your images (see 
“Creating a Slideshow on the 
Fly” on page 118). You can’t 
have your camera connected 
at the same time.

Adjusting the Image Quality
You can use the Video menu to adjust the brightness, sharpness, color, 
tint, and contrast. If you’re projecting from a computer (but not 
through the 
DVI port), there are additional adjustments you can make 
(see page 127).
Adjusting Images from Video Sources
1. Press the Menu button on the remote control, then select the 
Video menu. 
You see the Video menu screen. (The actual settings may vary, 
depending on the selected input source. The Video menu below is 
for a composite video or S-video source.)
2. Use the  pointer button to highlight the desired option, then 
adjust it as needed:
■Position
If the image is slightly cut off on one or more sides, it may not 
be centered exactly. Use this setting to center it (not available 
for RGB video images).
■Brightness 
Lightens or darkens the overall image.
■Contrast
Adjusts the difference between light and dark areas.

Adjusting Computer Images
You can also adjust brightness, contrast, and sharpness when you’re 
projecting a computer image. In addition, if you’re projecting an 
analog RGB image transmitted through the 
Computer or BNC 
port(s), you can make several other settings. 
1. Press the 
Menu button on the remote control, then select the 
Video menu. 
You see a screen similar to the one below. (The settings will be 
different if you’re projecting a digital RGB image transmitted 
through the 
DVI port.)

be centered exactly. Use this setting to center it.
■Tracking 
Adjust this value to eliminate vertical stripes in the image.
note
You can also use the remote 
control’s 
Auto button to 
automatically reset the 
projector’s tracking, sync, 
resolution, and position 
settings. See page 28 for

Before adjusting tracking or 
sync, fill the screen with an 
image containing fine 
detail. For example, in 
Windows you can select a 
pattern to appear as your 
desktop background. If this 
option isn’t available, try 
projecting black text on a 
white background.

■Sync
Adjust this value if the image appears blurry or flickers.
■Brightness
Lightens or darkens the overall image.
■Contrast
Adjusts the difference between light and dark areas. Select 
Auto to let the projector adjust the contrast automatically, or 
select 
Manual to adjust the setting yourself. (Press Enter after 
you make the selection.)
■Sharpness
Adjusts the sharpness of the image.
■Resolution
If your image is distorted (compressed, stretched, partially cut 
off, or doesn’t completely fill the display area), the projector’s 
resolution setting may not match that of your computer. 
Select 
Auto to let the projector adjust the resolution 
automatically, or 
Manual to adjust the setting yourself. (Press 
Enter after you make the selection.)
■Preset
Once you’ve fine-tuned the settings in the Video menu for 
the computer you’re using, you can save them as a group 
using one of the ten 
Preset settings. The next time you use 
the same computer, simply press the 
Preset button on the 
remote control to recall your saved settings. (Press the 
Preset 
button repeatedly to select the number corresponding to the 
setting you want to use.) 
						

							Using the Projector’s Menus129
Adjusting the Image Size, Shape, and 
Position
Whether you’re projecting from a computer or video player, you can 
use these settings to adjust the size, shape, and position of the image.
■Resize button
Adjusts how an image fits into the display area. 
For computer images, resizing is normally unnecessary, since the 
projector automatically resizes the image to make the best use of 
the display area. If you press the 
Resize button on the remote 
control, the projector displays the image at the output resolution 
of the computer (which makes the image larger or smaller, 
depending on its resolution). If the resolution of the image is the 
same as the projector’s (1024 
× 768), pressing Resize has no 
effect. 
For video images, pressing resize switches the aspect ratio between 
4:3 and 16:9. This lets you play certain digital video images or 
movies recorded on certain DVDs in 16:9 widescreen format. 
■Keystone (in the Setting menu)
Squares up the shape of the image after the projector has been 
tilted upward or angled to one side (see page 26). If you notice 
lines or edges looking jagged after adjusting the shape, decrease 
the Sharpness setting (see page 128). 
■Position (in the Video menu)
If the image is slightly cut off on one or more sides, it may not be 
centered exactly. You can use this setting to center it (not available 
for digital RGB or RGB video images). 
note
If your computer image is 
stretched, compressed, or 
doesn’t fit correctly on the 
screen, you should try 
adjusting the Resolution 
setting first (see page 128). 
						

							130Using the Projector’s Menus
Adjusting the Color
The projector provides several ways for you to adjust the color:
■Color Mode button (also in the Video menu) 
Lets you quickly adjust the color and brightness for various 
environments. Use either the remote control or the 
Color Mode 
setting in the Video menu; you can save a different setting for 
each computer and/or video source. Select from these settings:
sRGB: To use the sRGB standard for computer displays (the 
default when projecting from a computer with analog video)
Dynamic: For presentations in bright rooms 
Presentation: For presentations in dark rooms
Theatre: For optimizing movie images with natural color (the 
default for video display)
Living Room: For optimizing video games
■Color (in the Video menu)
Adjusts the color intensity, from black-and-white to full color 
(not available for adjusting computer images).
■Tint (in the Video menu)
Adjusts the balance of magenta to green (not available for 
adjusting computer images or RGB video images).
■Color Adjustment (in the Advanced 1 menu)
Adjusts the color temperature. Select 
Color Temp. to set a 
temperature between 5000 and 10000 °K. Or select 
RGB to 
adjust individual red, green, and blue values, as shown. (Not 
available if 
sRGB is selected as the Color Mode setting.)
