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.
