1. Floor in front of screen; 
2. Ceiling in front of screen; 
3. Floor at rear of screen; or 
4. Ceiling at rear of screen. 
Your room layout or personal preference will dictate which installation location you select. Take into 
consideration the size and position of your screen, the location of a suitable power outlet, as well as the location 
and distance between the projector and the rest of your equipment. 
For Setting menu options and descriptions, please refer to page 21.
I. Floor front: 
Select this location with the projector placed near 
the floor in front of the screen. This is the most 
common way to position the projector for quick 
setup and portability.II. Ceiling front:

Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the 
projected image size. BenQ has provided separate tables of dimensions for both 16:9 and 4:3 screen ratios to 
assist you in determining the ideal location for your projector.
1. Determine the aspect ratio of your screen, (16:9 or 4:3) ?
2. Select the Screen Size you desire from the 16:9 ratio screen dimension table or 4:3 ratio screen dimension 
table below, according to what screen type you have. Install the projector at a distance from the screen 
corresponding to between the Min. and Max. Projection Distance values in the table.
3. Decide the exact height of your projector.
For example, if you are using a 16:9 screen with 80 inches diagonal, you are suggested to place your projector 
within a range between 2.76m to 3.39m from the screen. The exact height of your projector will be 33 to 34cm 
above or below your screen from the center of the lens.

An examination of the table reveals that you can place the projector lens in the range from 1.73 to 8.47m distance 
from the screen, which will give you a projected image from 1.11 x 0.62m to 4.43 x 2.49m full screen.

Preparations
Tu r n i n g  t h e  p o w e r  o n
1. Check that the Power indicator lights orange after power has been 
applied.
2. Press and hold the Power button on the projector or remote control 
to turn the projector on. The Power indicator light flashes for about 
30 seconds during warm up, then remains constantly on (and the 
projector starts projecting) when ready.
3. Press Source on the projector or one of the Source buttons on the 
remote control to select your desired input signal. A message shows 
on the screen when the port is being searched.
If you would like to change the input signal, please see below.
Switching input signals
To sequentially select input signals, press one of the Source buttons on the 
remote control or Source on the projector. 
The selected source will be displayed at the bottom right of the screen for 3 
seconds. 
Activate the Source Scan function in the Advance menu if you want the 
projector to automatically search input ports. It may take a few 
seconds for the projector to search for input signals.
Adjusting the image
Adjusting the angle height
The projector is equipped with 1 front quick-release adjuster foot and 2 
rear adjuster feet. These adjusters change the image height and 
projection angle. To adjust the projector: 
1. Lift the projector up and press the adjuster button to release the 
adjuster. The front adjuster foot will drop into position and lock 
into place when you release the button. It can lift the projector by 
up to 15 degrees. Manually screw it up or down for fine height adjustment.
2. Screw the rear adjuster feet to adjust the horizontal angle so that the projector is stable and the projection 
is level. 1. Turn all of the connected equipment on.
2. Remove the lens cap. 3. Plug the supplied power 
cord into the AC inlet on 
the rear of the projector. 
4. Plug the power cord into 
a wall socket and turn the 
wall switch on. 
						

							16 Using the projector and remote control  
Auto-adjusting the image
With one press of the Auto button on the projector or remote control, the 
built-in intelligent Auto-adjustment function will re-adjust the values of 
Frequency and Clock to provide the best image quality.
The current source information will be displayed at the bottom right of the 
screen for 3 seconds.
The screen will be blank while Auto adjustment is functioning.
Correcting Keystone picture distortion
Keystone picture distortion (keystoning) occurs in situations where the 
projector is not perpendicular and level with the centre of the screen. It 
results in the projected image being wider at either the top or bottom of the 
image, (seen in the shape of a building stone archway keystone  ).
If you cannot alter the location of the projector, you can manually correct 
for it by following any one of these steps:
•Press 3 Left or Right 4 (hot key) on the projector to display the status 
bar labelled Keystone. Press 3 Left to correct keystoning at the top of the 
image. Press Right 4 to correct keystoning at the bottom of the image.
•Press  or  on the remote control to display the 
status bar labelled Keystone, then press  to correct 
keystoning at the top of the image or press   to 
correct keystoning at the bottom of the image.
Fine-tuning the image size and clarity
1. Adjust the projected image to the size that you 
need using the zoom ring. 2. Then sharpen the image by rotating the focus 
ring.

If the projector was not properly shut down, and you attempt to restart it soon thereafter, the fan may run 
for a few minutes to cool it down properly before you can restart. You will have to wait before you can 
press Power again to start the projector after the fans stop.
