LV-WX300UST (4/6)

■Installation distance and image size

Projection lens for this projector doe not feature optical zoom function.

For this reason, image size is adjusted by moving the installation position (throw distance).

“L” in the diagram (left) represents throw distance. It

is the horizontal distance from the front of the

projector to the screen.

H represents the image height; it is the vertical

distance from the top to the bottom of the image.

Hs is the distance in vertical direction from the

bottom of the projector to the top of the image.

Ratio between H and Hs for this projector is fixed, as

shown below:

LV-WX300UST

10:2.5 (Hs = H x 0.25)

Although it is not shown in this diagram, the width of

the image is indicated with W.

Note: Although this projector can be used in a conventional

position (placed on a desktop), it is designed to be

mounted on a wall up-side-down, using a bracket.

Optimum displayable images sizes are between 80 to 100 inches.

Image size and throw distance are as indicated below.

Note: Figures in the above chart are approximate.

This projector adopts aspheric mirror for its optical system. For this reason, there

is a gap between installation distance and projection distance as shown in the

diagram on the right. The difference is expressed with the following formula.

L' = L + 32.0

Projection ratio is calculated with the above formula using throw distance, not

installation distance.

Projection ratio is not proportional to the throw distance because the image size

at the starting point for throw distance is not zero.

This projector features 3 adjustable feet.

Feet are used to adjust left/right tilt.

The projection angle can be adjusted up to 2.0 degrees between the projector

and installation surface.
