Positioning your projector
Choosing a location
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.
Your projector is designed to be installed in one of the possible installation locations: 
For ceiling mounting, you need the ceiling mount kit designed for this projector. Ask a specialist for installation.For 
details, consult your dealer.
• The warranty on this projector does not cover any damage caused by use of any non-recommended ceiling mount 
kit or installation of the ceiling mount kit in an improper location.
• When the projector is mounted on the ceiling, images may appear darker than those projected in the case of 
tabletop mounting. This isn’t a product malfunction.
Be sure to use this projector at an altitude of less than 1500 meters.
1. Front Table
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.
2. Rear Table
Select this location with the projector placed near the 
floor behind the screen.
Note that a special rear projection screen is required.
Set Rear Table in the SYSTEM SETUP: Basic > 
Projector Position menu after you turn the projector on.
3. Rear Ceiling
Select this location with the projector suspended upside-
down from the ceiling behind the screen.
Note that a special rear projection screen and qualified 
projector ceiling mount kit are required for this 
installation location.
Set Rear Ceiling in the SYSTEM SETUP: Basic > 
Projector Position menu after you turn the projector on.
4. Front Ceiling
Select this location with the projector suspended upside-
down from the ceiling in front of the screen.
Purchase a qualified projector ceiling mount kit from 
your dealer to mount your projector on the ceiling.
Set Front Ceiling in the SYSTEM SETUP: Basic > 
Projector Position menu after you turn the projector on.

Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in 
the projected image size.
4:3 is the native aspect ratio of EX320U. To be able to project a complete 16:9 (widescreen) aspect ratio image, the 
projector can resize and scale a widescreen image to the projectors native aspect width. This will result in a 
proportionally smaller height equivalent to 75% of the projectors native aspect height.
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed by this projector. This 
will be seen as darkened (unlit) bars along the top and bottom (vertical 12.5% height respectively) of the 4:3 
projection display area whenever displaying a scaled 16:9 aspect image in the vertical center of the 4:3 projection 
display area.
16:10 is the native aspect ratio of EW330U. To be able to project a complete 16:9 (widescreen) aspect ratio image, the 
projector can resize and scale a widescreen image to the projectors native aspect width. This will result in a 
proportionally smaller height equivalent to 90% of the projectors native aspect height.
Thus, a 16:9 aspect image will not utilize 10% of the height of a 16:10 aspect image displayed by this projector. This 
will be seen as darkened (unlit) bars along the top and bottom (vertical 5% height respectively) of the 16:10 projection 
display area whenever displaying a scaled 16:9 aspect image in the vertical center of the 16:10 projection display area.
The projector should always be placed horizontally level (like flat on a table), and positioned directly perpendicular 
(90° right-angle square) to the horizontal center of the screen. This prevents image distortion caused by angled 
projections (or projecting onto angled surfaces). 
The modern digital projector does not project directly forward (like older style reel-to-reel film projectors did). 
Instead, digital projectors are designed to project at a slightly upward angle above the horizontal plane of the 
projector. This is so that they can be readily placed on a table and will project forward and upwards onto a screen 
positioned so that the bottom edge of the screen is above the level of the table (and everyone in the room can see the 
screen).
You can see from the diagram on page 14, that this type of projection causes the bottom edge of the projected image to 
be vertically offset from the horizontal plane of the projector.
If the projector is positioned further away from the screen, the projected image size increases, and the vertical offset 
also increases proportionately.
When determining the position of the screen and projector, you will need to account for both the projected image size 
and the vertical offset dimension, which are directly proportional to the projection distance.
When fine streaks are seen on projected images
This is due to interference with the screen surface and is not a mal-function. Replace the screen or displace the focus a 
little.

How to determine the position of the projector for a given screen size
1. Determine the aspect ratio of your screen, 16:9 or 4:3. If you have a 4:3 screen, refer to the table labeled 
(Standard). If you have a 16:9 screen, refer to the table labeled (16:9).
2. Select your screen size.
3. Refer to the table and find the closest match to your screen size in the left columns labeled Screen. Using this 
value, look across this row to the right to find the corresponding average distance from screen value in the 
column labeled Distance from the screen: L. This is the projection distance.
4. On that same row, look across to the right column and make note of the Hd value. This will determine the final 
vertical offset placement of the projector in relation to the edge of the screen.
5. The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the 
distance from the screen determined in step 3 above, and offset by the value determined in step 4 above.
EX320U: For example, if you are using a 4:3 aspect ratio, 100-inch screen, distance from the screen is 3.1 m and with 
a vertical offset of 11 cm at Zoom position wide.
EW330U: For example, if you are using a 4:3 aspect ratio, 100-inch screen, distance from the screen is 2.6 m and with 
a vertical offset of 3 cm at Zoom position wide.
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 keystone on page 26 for details.
How to determine the recommended screen size for a given distance
This method can be used for situations where you have purchased this projector and would like to know what screen 
size will fit in your room.
The maximum screen size is limited by the physical space available in your room. 
1. Measure the distance between the projector and where you want to position the screen. This is the projection 
distance.
2. Refer to the table (Standard) or (16:9), and find the closest match to your measurement in the distance from 
the screen column. If the min and max values are available on the table, check that your measured distance is 
between the min and max distances listed on either side of the average distance value.
3. Using this value, look across that row to the left to find the corresponding Screen. That is the projected image 
size of the projector at that projection distance.
4. On that same row, look across to the right column and make note of the Hd value. This will determine the final 
placement of the screen in relation to the horizontal plane of the projector. 
EX320U: For example, if your measured projection distance was 3.5 m and your screen aspect ratio is 4:3, the closest 
match in the Distance from the screen: L column is from 3.1 m to 4.0 m. Looking across this row shows that a 100-
inch screen is required.
EW330U: For example, if your measured projection distance was 4.5 m and your screen aspect ratio is 4:3, the closest 
match in the Distance from the screen: L column is from 3.9 m to 5.1 m. Looking across this row shows that a 150-
inch screen is required.

Connecting Video source devices
You can connect your projector to various Video source devices that provide any one of the following output sockets:
• HDMI
• Component Video
•S-Video
• Video (composite)
You need only connect the projector to a Video source device using just one of the above 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:
HDMI (High-Definition Multimedia Interface) supports uncompressed video data transmission between compatible 
devices like DTV tuners, DVD players and displays over a single cable. It provides pure digital viewing experience. 
See Connecting an HDMI device on page 18 for how to connect the projector to an HDMI device.
Digital TV tuner and DVD players output Component Video natively, so if available on your devices, this should be 
your connection method of choice in preference to (composite) Video. See Connecting a Component Video source 
device on page 18 for how to connect the projector to a component video device.
If you have both composite Video and S-Video output terminals on your Video source device, you should elect to use 
the S-Video option. See Connecting an S-Video source device on page 19 for how to connect the projector to an S-
Video device.
If you have only composite Video output terminals on your Video source device, connect to Composite Video input.

2. Connect the other end of the cable to the HDMI input port on the projector.
In the unlikely event that you connect the projector to a DVD player via the projectors HDMI input and the projected picture 
displays wrong colors, please change the color space to YUV. See Changing Color Space on page 24 for details.
When you connect this projector and a Digital device (such as a DVD player) via the HDMI terminal, black color may appear dark 
and deep, depending on the type of the connected device.
• This depends on the black level setting of the connected device. There are two kinds of methods to digitally transfer image 
data, in which different black level settings are employed respectively. Therefore, the specifications of the signals output 
from DVD players differ, depending on the type of the digital data transfer method they use.
• Some DVD players are provided with a function to switch the methods to output digital signals. When your DVD player is 
provided with such function, set it as follows.
EXPAND or ENHANCED -> NORMAL
• See the users guide of your DVD player for details.
• When you switch to HDMI input, the projected picture may display wrong colors for about 1 second. This is not product 
malfunction.
