EnglishConnecting a computer
Connect the projector to a computer with a VGA cable. 
Many laptops do not turn on their external video

combination.
Connecting a monitor
If you want to view your presentation close-up  on a monitor as well as on the screen and the 
MONITOR OUT  jack is available on your projector, you can connect the  MONITOR OUT signal 
output jack on the projector.
•  The MONITOR OUT only works when an appropriate D-Sub input is made to the PC jack.
•  If you wish to use this connection  method when the projector is in standby mode, make sure the Monitor 
Out function is turned on in the  System Setup: Advanced menu. See Monitor Out on page 59  for

EnglishAdjusting the projected image
Adjusting the projection angle 
There are two adjuster feet on the bottom of the projector. 
These can be used if necessary to change the projection angle. 
Screw the feet in or out as appropriate to aim and level the 
projection angle.
If the screen and the projector are not perpendicular to each 
other, the projected image beco mes vertical trapezoidal. To 
correct this problem, see  Correcting picture distortion on 
page 30  for details.
Auto-adjusting the image
In some cases, you may need to opti mize the picture quality. To do this, 
press AUTO. Within 3 seco nds, the built-in Intelligent Auto Adjustment 
function will re-adjust the values of Frequency and Clock to provide the 
best picture quality.
The current source information will be displayed in the corner of the 
screen for 3 seconds.
This function is only available when a PC signal  (analog RGB) is selected.
Fine-tuning the image size and clarity
1. Adjust the projected picture to the size 
that you need using the zoom ring. 2. Sharpen the picture by rotating the focus 
ring. 
						

							30 Using the projector  
EnglishCorrecting picture distortion
Keystoning occurs when the projector is not perpen
dicular to the screen and is where the projected 
picture displays visible as a trapezoid shape like either of the following:
•  Two parallel sides (left and right, or top and bottom) but is noticeably wider on either side.
•  No parallel sides.
To correct the picture’s shape, you can perform the following steps.
1. Adjust the projection angle. Move the projector to  be in front of the center of the screen with the 
center of the lens level with the screen.
2. If the picture is still distorted, or the projector is unable to be posi tioned as described above, you will 
need to manually correct the picture by using the  2D Keystone and Corner Fit  functions. 
The 2D Keystone function is closely related to the Corner Fit function as both make adjustments to correct 
picture distortion. When correcting picture distortion , use the following procedure to adjust 2D Keystone 
and Corner Fit functions in order to achieve the best picture shape:
1. Use  2D Keystone  function to adjust the picture roughly to the correct shape.
2. Use  Corner Fit  funtion to fine tune the corners to acheive best picture shape.
3. If optimal effect cannot be achieved using  Corner Fit, reset 2D Keystone  and repeat steps 1 and 2.
2D Keystone and Corner Fit functions are closely correlated, when 2D Keystone is over adjusted, the 
adjustment range for Corn er Fit will be limited. 
Using 2D Keystone function
•  Using the remote control or projector
i. Press one of the Arrow/Keystone keys (Left  / , Up  / , 
Right  / , Down / ) to display the  2D Keystone page.
ii. See step  iii below for further operation.
•  Using the OSD menu
i. Press  MENU/EXIT  and then press  /  until the  Display 
menu is highlighted.
ii. Press  to highlight  2D Keystone and press MODE/
ENTER . The 2D Keystone  page is displayed.
iii. Press the key whose keystone icon is opposite to the shape of the projected picture. Continue  pressing the same key or press the other keys until you are satisfied with the shape.
The values on the lower portion  of the page change while pressing. When the values reach their 
maximum or minimum with repeated key presses,  the picture’s shape will stop changing. You will 
not be able to change the picture further in that direction.
iv. If desired picture shape cannot be achieved, press  MODE/ENTER to reset 2D Keystone  
value and repeat the previous step.
When resetting 2D Keystone, both 2D Keystone an d Corner Fit values will return to default value.
v.When done, press MENU/EXIT to go back to the previous page.
