Positioning your projector
Choosing a location
Your projector is designed to be installed in  one of four possible installation locations.
Your room layout or personal preference will dictate which installation location you select. Take into 
consideration the size and position of your screen, th e location of a suitable power outlet, as well as the 
location and distance between the proj ector and the rest of your equipment.
*To set the projector position:
1. Press MENU/EXIT and then press  /  until the System Setup: Basic menu is highlighted.
2. Press  /  to highlight Projector Installation a nd press  /  until the correct position is selected.
1. 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.3. Rear:
Select this location with the projector placed near 
the floor behind the screen.
Note that a special rear projection screen is 
required.
*Set Rear after you turn the projector on.
2. Front Ceiling:
Select this location with the projector suspended 
from the ceiling in front of the screen.
Purchase the BenQ Projector Ceiling Mount Kit 
from your dealer to mount your projector on the 
ceiling.
*Set Front Ceiling after yo
u turn the projector on.
4. Rear Ceiling:
Select this location with the projector suspended 
from the ceiling behind the screen.
Note that a special rear projection screen and the 
BenQ Projector Ceiling Mount Kit are required for 
this installation location.
*Set Rear Ceiling after yo u turn the projector on. 
						

							14 Positioning your projector  
EnglishObtaining 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. The diagrams from pages 15 to 17 offer recommendations on projection 
distances and screen sizes.
This projector is equipped with a movable lens. See  Shifting the projection lens on page 18 for details. 
You can see the diagrams from pages  15 to 17 for the vertical offset values in the dimension tables that 
are measured when the lens is shifted fully up or down.
If you place the projector in a different position (to th at recommended), you will have to tilt it down or 
up to center the image on the screen. In these situ ations, some image distortion will occur. Use the 
Keystone function to correct the distortion. See  Correcting picture distortion on page 30 for details.

Installation for a 16:10 ratio screen
SU922/SW921
 The screen aspect ratio is 16:10  and the projected picture is 16:10
•  SU922
If you have a 16:10-aspect-ratio screen and your me asured projection distance was 4.5 m (450 cm), the 
closest match in the  Average column is 450 cm. Looking across this row shows that a 150-inch screen 
is required.
Checking the min and max projection  distance values in the columns of Projection distance  [cm] 
indicates that the 4.5 m measured projection distance will also fit the 13 0 and 140-inch screens, as well as 
160 to 190-inch size screens. The projector can be adju sted (using the zoom control) to display on these 
different screen sizes at the projection distance.
The above numbers are approximate and may be slightly different from the actual measurements. Only the 
recommended screen sizes are listed. If your screen size is not in the table above, please contact your dealer 
for assistance.

							18 Positioning your projector  
EnglishShifting the projection lens
The lens shift control provides flexibility for installing your projector. It allows the projector to be 
positioned off the center of the screen.
The lens shift is expressed as a percentage of the pr
ojected image height or width. It is measured as an 
offset from the projected image’s vertical or horizontal  center. You can shift the projection lens in vertical 
directions within the allowable range depe nding on your desired image position. For  SU922 and 
SW921 , the maximum vertical shift is 5% from the vertical center. For SX920 , the maximum vertical 
shift is 15% from the vertical center. For all  three models, horizontal shift is not available.
To shift the lens vertically:
1. Press down lightly on the lens adjustment panel cove r switch (indicated by the three dots) to click it 
open.
2. Lift the lens adjustment panel cover up.
3. Turn the lens shift ring to ad just the projected image position.
4. When done, press down and click close the lens adjustment panel cover.
•  Lens shift adjustment will not result  in a degraded picture quality. In the unlikely event that the image 
distortion is produced, see  Adjusting the projected image on page 29  for details.

  Connecting to video equipment
English
Connecting to video equipment
You can connect the projector to any  type of video equipment, such as a DVD or Blu-ray player, digital 
tuner, cable or satellite decoder, video game consol e or digital camera. You can also connect it to a 
desktop PC, a laptop PC, or Apple  Macintosh system. You can connect the projector to a source device 
using just one of the connecting methods; however, each provides a different level of video quality. The 
method you choose will most likely depend upon the availability of ma tching terminals on both the 
projector and the video source device as described below:
Preparations
When connecting a signal source to the projector, be sure to:
1. Turn off all equipment befo re making any connections. 
2. Use only the correct type cables for  each source with proper type plugs. 
3. Ensure that all cable plugs are firm ly fitted to the equipment jacks. 
Note that all cables shown in the following connection  diagrams may not be supplied with the projector (See 
Shipping contents on page 6  for details). Most cables are comme rcially available from electronics 
stores.
Connecting HDMI devices
HDMI (High-Definition Multimedia Interface) suppo rts uncompressed video data transmission between 
compatible devices like DTV tuners,  DVD or Blu-ray players and displays over a single cable. It provides 
pure digital viewing and listening experience. You sh ould use an HDMI cable when making connection 
between the projector and HDMI devices.
