							Setting Up the Projector51
Removing the USB Device or Cable
If you’re using PC Free mode to project your images, videos, or 
presentations, stop the projection before you remove the USB device 
or cable from the projector.
1. If you’re projecting a still image, press the 
Esc button on the 
remote or the projector’s control panel.
2. If you’re projecting a slideshow of your images, a movie, or a 
presentation, press the 
Esc button on the remote or the 
projector’s control panel. Then select 
Exit in the window that 
appears and press the 
Enter.
3. Turn off your digital camera or other device.
4. Disconnect the USB device or cable. 
Turning the Projector On and Off 
Turn on any connected computer or video equipment before starting 
the projector so it can automatically detect and display the image 
source. If you turn on the projector first, or have multiple pieces of 
connected equipment, you may have to select the image source 
manually (see page 56). 
Follow these steps to turn on the projector: 
1. Remove the lens cover. 
note
You can set the projector to 
automatically turn off the 
lamp and enter “sleep mode” 
when it has not received any 
signals for 1 to 30 minutes 
(see page 126 to enable, 
disable, or adjust this 
setting). This conserves 
electricity, cools the 
projector, and extends the 
life of the lamp. If you want 
to start projecting again, 
press the 
P power button. If 
you are done using the 
projector, unplug the power 
cord.  
						

							52Setting Up the Projector2. Plug one end of the power cord into the projector, and the other 
end into an electrical outlet.
The Ppower light turns orange.
3. Press the Ppower button on the remote control or on the back of 
the projector.

							Setting Up the Projector53
The projector beeps once and the Ppower light flashes green as 
the projector warms up, then an image begins to appear. When 
the Ppower light stops flashing and remains green, the projector 
is ready for use. 
4. If you are prompted to enter a password, see page 122.
Using the Direct Power On Function
The Direct Power On function enables faster setup. The projector 
starts up automatically when you plug it in or turn it on with a wall 
switch. You don’t have to press the Ppower button. 
Follow these steps to enable Direct Power On: 
1. Press the 
Menu button on the remote control or projector, then 
select the 
Extended menu and press Enter.
2. Choose 
Operation and press Enter. 
3. Choose 
Direct Power On and press Enter.
4. Highlight 
On and press Enter. 
5. Press 
Menu to exit. The setting will take effect the next time you 
plug in the projector.
warning
Never look into the lens 
when the lamp is on. This 
can damage your eyes, and is 
especially dangerous for 
children and pets.
note
If a power outage occurs 
when Direct Power On is 
enabled and the projector is 
plugged in, the projector will 
restart when the power is 
restored.

Displaying and Adjusting 
the Image
Follow the guidelines in this chapter for: 
■Displaying an image
■Adjusting the image
■Projecting two images simultaneously 
						

							56Displaying and Adjusting the Image
Displaying an Image
You may need to select the image source if you have multiple video 
sources connected to the projector (such as a computer or DVD 
player). Selecting the image source lets you switch between images 
input from different pieces of connected equipment. 
If you don’t see the image you want, press the 
Search button or one 
of the 
Source buttons on the remote control, or the Source Search 
button on the projector until you see the image you want to project.
You can also use the 
Source buttons on the remote control to switch 
between devices connected to the ports identified on each button.
Adjusting the Image
Once you see your image, you need to make certain adjustments:
■If the image is too high or too low, reposition it as described on 
page 57.
■To focus or zoom your image, see page 58. 
■If the image isn’t square, see page 58.
■To quickly adjust the color, brightness, or contrast, see page 60.
■To change the image aspect ratio, see page 61.
■If you need to fine-tune the image and/or sound, see Chapter 5.
note
The projector can display a 
test pattern to help you 
adjust some image settings. 
See page 119. 
						

							Displaying and Adjusting the Image57
Adjusting the Position of the Image
You can use the vertical lens shift dial on the top of the projector to 
move your image up or down, or you can use the horizontal lens shift 
dial to move your image left or right.
Additionally, if the projector is on a table, you can use the projector’s 
adjustable feet to adjust the image:
1. Stand behind the projector. Press the foot release lever up and lift 
the front of the projector.
2. Once the image is positioned where you want it, release the lever 
to lock the foot in position.
Vertical Horizontal 
note
Raising the projector with 
the front adjustable foot 
causes the image shape to 
distort or “keystone,” but 
you can correct the shape as 
described on page 58. 
						

							58Displaying and Adjusting the Image3. If necessary, you can fine-tune the height or level the image by 
turning any of the projector’s adjustable feet.
Focusing and Zooming the Image
Turn the focus ring on the projector to sharpen the image. 
Turn the zoom ring (using the knobs on the ring) to reduce or enlarge 
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 
buttons on the remote control to zoom in on a portion of the image. 
See page 68 for instructions. 
Adjusting the Image Shape
You can maintain a square or rectangular image by placing the 
projector directly in front of the screen and keeping it level. This also 
produces the best picture quality. If the projector is tilted up or placed 
at an angle, you’ll need to correct the image shape by using one of the 
functions described below. 
Using Quick Corner
Use Quick Corner to adjust the shape and size of the image when it’s 
uneven on all sides. Follow these steps to select 
Quick Corner:
1. Press the 
Menu button on the remote control or the projector.
2. Select the 
Settings menu and press Enter. 
3. From the Settings menu, select 
Keystone and press Enter. 
4. Select 
Quick Corner and press Enter twice.
note
If you have installed the 
Rear Projection Wide Lens 
(part number 
V12H004R03), you cannot 
use the zoom ring to reduce 
or enlarge the image, but 
you can still use the 
E-Zoom buttons on the 
remote control.
Focus Zoom  
						

							Displaying and Adjusting the Image59
You see this screen:
5. Use the  pointer button on the remote control (or the arrow 
buttons on the projector) to select the corner you want to adjust, 
and press 
Enter.
6. Use the  pointer button on the remote control (or the arrow 
buttons on the projector) to adjust the shape, then press 
Esc when 
you are finished.
7. Repeat steps 5 and 6 as needed to adjust the other corners. 
8. When you’re done, press 
Esc to exit.
Using Keystone Correction
You can manually adjust the shape of the image to compensate for 
vertical and horizontal keystone distortion.
Before performing horizontal or vertical keystone, use the lens shift 
function to horizontally center the lens and vertically move the lens to 
the top or bottom (see page 57); otherwise, the distortion will not be 
corrected accurately. Also, the distortion may not be corrected 
accurately for some zoom settings.
1. Press the 
Menu button on the remote control or projector.
2. Select the 
Settings menu and press Enter. 
3. From the Settings menu, select 
Keystone and press Enter. 
4. Select 
H/V-Keystone and press Enter.
note
To undo your Quick Corner 
adjustments, press and hold 
the 
Esc button for about 2 
seconds, select 
Reset Quick 
Corner
 from the screen that 
appears, then press Enter.
note
Epson recommends using 
Quick Corner to accurately 
adjust keystone distortion. 
See page 58.
note
You can also use the 
projector’s arrow buttons to 
perform keystone correction 
as long as the projector’s 
Keystone setting is set to 
H/V-Keystone. 
						

							60Displaying and Adjusting the Image5. Select 
H-Keystone (for horizontal adjustment) or V-Keystone 
(for vertical adjustment) and use the  pointer button on the 
remote control to adjust the shape of the image.
If the image becomes smaller, use the zoom ring to enlarge the 
image so it fits the screen. If the image contains faint lines or a 
gridlike pattern, decrease the sharpness setting (see page 115).
6. When you’re done, press 
Menu to exit.
Selecting the Color Mode
The Color Mode adjusts the brightness, contrast, and color for various 
common viewing environments. Use this setting to quickly obtain a 
good picture.
Press the 
Color Mode button on the remote control, and then select 
from one of these options:
■Dynamic: Brightest mode; for video games or TV in a bright 
room.
■Presentation: For making color presentations in a bright room.
