Wall Mount Installation TIPS
DIMENSIONS
Adhering to proper installation dimensions is always imperative, and
is especially critical when dealing with an Ultra Short Throw Projector.
Because the distance from the projector to the display surface is
so short, even a small differential can cause a large error. In fact, the
impact of not meeting dimensional requirements is roughly 5 times that of a
normal throw distance projector. While you can manage an installation tolerance
of one inch with a normal throw distance projector, you cannot manage this same tolerance with an
Ultra Short Throw Projector.
Please pay attention and read the User Manual, Instruction Manual and Drawings that will be
provided from manufacturer. If you have any questions or are unsure of any of the steps involved,
please ask before proceeding.
SURFACE
Having a flat projection surface is very important. Since the throw
distance is so short, waves or bends of the projection surface can
produce wavy, un-even and out of focus images. For this reason
– most pull up / down screens are not recommended. Hard board,
flat wall or fixed frame screens are preferred for usage with an Ultra
Short Throw Projector.
MARGIN
The very nature of an Ultra Short Throw Projector can produce some
image distortion. The range of distortion is dependent upon the
individual unit, operation temperature and various environmental
factors. Look at the balance of whole image area, rather than focusing
on a particular area or corner. When installing with an Interactive White
Board (IWB), please allow for 1” margins on the (left, right, top, and
bottom) edges, and then use the calibration function of the IWB. With
a fixed frame installation, consider slightly over scanning for a video signal or allowing for the proper
margin necessary for a computer signal.
STRATEGY
In an Ultra Short Throw installation, every adjustment is sensitive,
with small changes having a large effect. Because many
variables are involved, making adjustments can be confusing.
But, in fact, this Ultra Short Throw Projector is a fixed projector,
so the ideal location is always the same.
In order to get a square image without the use of electrical keystones, zoom and shift, please follow
the steps describe on the next page.

Step 1 Preparation
Reset all Keystones (Keystone = 0), Electrical Zoom settings (Zoom = 100), etc… prior to starting
adjustments.
Warm up the projector (30 minutes) in order to reduce image distortion.
Step 2 Horizontal Keystone
Adjust the Pitch (left-right angle)
and Rotation to eliminate horizontal
keystone effect. The left-right angle
affects the top line of the image;
the rotation affects the bottom line
of image. Ignore vertical keystone
during this process.
Step 3 Vertical Keystone
Optimize Focus and adjust Tilt Angle
to eliminate horizontal keystone
effect. The Focus adjustment will
change the vertical keystone.
If you cannot make both vertical
edges parallel, you may need to go
back Step2 and re-fine the Rotation.
Step 3 Horizontal Position
Adjust horizontal position so it is
centered on the display area.
Step 4 Image Size
Adjust throw distance to match the
length of top image with display area.
You may see some geometrical
distortions, so please do not try to fill
entire area. You may need to do fine-
tuning later (vertical and horizontal
keystone or image positions). Leave
a half inch margin.
Step 4 Vertical Position
Adjust vertical position so it is
centered in the display area.
