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, the location of a suitable power outlet, as well as the 
location and distance between the projector 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 and 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 you 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 you turn the projector on.

  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 14 to 15 offer recommendations on projection 
distances and screen sizes.
This projector is equipped with a movable lens. See Shifting the projection lens on page 16 for details. 
You can see the diagrams from pages 14 to 15 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 that recommended), you will have to tilt it down or 
up to center the image on the screen. In these situations, some image distortion will occur. Use the 
Keystone function to correct the distortion. See Correcting picture distortion on page 28 for details.

Installation for a 16:10 ratio screen
SU931
 The screen aspect ratio is 16:10 and the projected picture is 16:10 
If you have a 16:10-aspect-ratio screen and your measured projection distance is 4.5 m (450 cm), the 
closest match in the Average column of the above table 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 Projection distance  [cm] columns of 
the above table indicates that the 4.5 m measured projection distance will also fit the 130 and 140-inch 
screens, as well as 160 to 190-inch size screens. The projector can be adjusted (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.

							16 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 projected 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 depending on your desired image position. For SU931, the 
maximum vertical shift is 2.5% from the vertical center. For SX930, the maximum vertical shift is 5% 
from the vertical center.
To shift the projection lens:
1. Press to open the cover on the projector to expose the lens shift knob. 
2. Rotate the knob clockwise or counterclockwise until the screen is positioned where you want it.
•  To avoid causing damage to the lens shift device, rotate the screw driver slowly and gently.
•  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 27 for details.
•  When the screen position is fixed

  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 console 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 matching 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 before making any connections. 
2. Use only the correct type cables for each source with proper type plugs. 
3. Ensure that all cable plugs are firmly 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 commercially available from electronics stores.
Connecting HDMI devices
HDMI (High-Definition Multimedia Interface) supports 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 should use an HDMI cable when making connection 
between the projector and HDMI devices.

EnglishConnecting MHL devices
MHL (Mobile High-definition Link) supports uncompressed HD video (1080/30p) and audio (7.1 
surround sound) transmission between compatible devices like smartphones, tablets and other mobile 
devices. It provides pure digital viewing and listening experience. You should use an MHL cable when 
making connection between the projector and MHL devices.
Not all mobile devices are MHL compatible. Consult with you mobile device manufacturer to verify MHL 
compatibility of your device.
Connecting S-Video devices
Connect the projector to your S-Video device with an S-Video cable. The audio connections are 
provided for informational purposes only. You can also connect a separate audio cable to a suitable audio 
amplifier.

EnglishConnecting video devices
The audio connections are provided for informational purposes only. You can also connect the separate 
audio cable to a suitable audio amplifier.
•  If you have already made a Component Video connection between the projector and the video source 
device, you need not connect to this device again using a composite Video connection as this makes an 
unnecessary second connection of poorer picture quality. 
•  If the selected video image is not displayed after the projector is turned on and the correct video source 
has been selected, please check that the video source device is turned on and operating correctly. Also 
check that the signal cables have been connected correctly.

							20 Connecting to video equipment  
EnglishConnecting a computer
Connect the projector to a computer with a VGA cable. 
Many laptops do not turn on their external video ports when connected to a projector. Usually a key 
combination like Fn + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled 
CRT/LCD or a function key with a monitor symbol on the laptop. Press Fn and the labeled function key 
simultaneously. Refer to your laptop
s documentation to discover your laptops key 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 58 for 
details.
