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.
