What it Sounds Like
On-board Audio:
The audio system’s 5-watt mono speaker delivers
enough volume for a mid-size room and good
enough sound quality for narration or movie
dialogue.

Fan Noise:
With Full Power, the WUX450ST is rated at 37 dB,
and is loud enough to be intrusive even from 15
feet away. In Power Saver mode, rated at 30 dB,
it’s still audible from 15 feet in a quiet room, but

find bothersome sitting just five feet away.

The vertical mode settings for facing the
projector up and down both raise the noise
level. However this shouldn’t be an issue, since
you’re most likely to use vertical mounting for
displays or signage.

starting at 7545 feet--50% higher than
for most projectors and higher than the
maximum elevation in all but 13 states in the
continental US. That makes it unlikely you’ll
ever need it. If you have to use it, however, it’s
easy to hear in full power mode from 40 feet
away. You’ll probably want to stay with Power
Saver mode instead, or consider putting the
projector behind a false wall to help deaden
the sound.

OUR LAB TESTS: What the Meters Say:
Brightness:
ANSI lumen measurements on the WUX450ST
were as follows:
were as follows:
The last two modes don’t show as choices unless
you change a menu setting from the factory
default, and neither is available at all when using
the LAN, USB ports, or a PC connected by VGA.
When they are available, they replace the first
two, so the menu choices at any point are
Photo/sRGB either with Presentation and
Standard or with Dynamic and Video.

Low Lamp Mode:
Power Saver mode drops brightness to about
75% of Full Power, which is still easily bright
enough for many classrooms and conference
rooms. It also increases lamp life from 3000
hours to 5000, making it well worth using.

Presentation Optimized Lumens:

quality, so you can pick the one that offers the
most appropriate brightness for the image size
and light level.

Video Optimized Lumens:
Here again, all five modes deliver solid video,
but the best choice for most video is
Presentation mode with a slight tweaking of
the color temperature, which gives better color
balance, and brought the brightness down just
a hair, to 3638 lumens.

Zoom Lens Effect:
The short throw lens doesn’t offer zoom, so
there’s no zoom lens effect to curtail light.
there’s no zoom lens effect to curtail light.
Brightness Uniformity:
The measured 71% uniformity is less than
most projectors deliver, but not unusual for a
short-throw lens. More important, the dimmest
and brightest areas are far enough apart that
the difference is barely noticeable with a solid
white image even if you look for it. It’s impossible
to see with any image that breaks up the field
of view.

19 to 23 ms depending on the preset mode.

Setting it Up
Throw Distance:
With no zoom, the WUX450ST is limited to
a fixed distance for any given size image.
For the native 16:10 aspect ratio, it can throw
a 120” diagonal image from roughly 4.75 feet,
and a 150” image from six feet. To find the
right range for the image size you want,
see the

Lens Shift:
With the projector on a table in front of the
screen, and at the bottom extreme of the
vertical shift range, 50% of the 16:10 image is
above the centerline of the lens, and 50% is
below. At the top of the range, the bottom edge
of the image is 30% of the image height above
the centerline of the lens. Depending on the
vertical shift setting, the horizontal shift varies

If you have to tilt or swivel the projector even
after taking advantage of the lens shift, you
can manually adjust for up to plus or minus
12 degrees for both vertical and horizontal
keystone distortion. Alternatively, you can
individually adjust each corner.
