Image Quality—Superior brightness
All EPSON multimedia projectors include EPSON's integrated LCD prism technology. This technology is centered
on EPSON's patented optical engine.
Three-panel design:
EPSON's engine includes 3-panel Poly-Silicon TFT LCD's:
▲▲
Size ranging from 1.32 inches to 0.9 inches
Resolutions from SVGA to XGA to SXGA.
Improvements in the precision of this LCD structure has allowed
EPSON projectors to reach a superior level of brightness with a
combination of these five technologies, included in most EPSON
projectors:
1. UHE lamp:
The long-life Ultra High Efficiency (UHE) lamp uses a shorter arc
length. This shorter length is the primary factor in achieving higher
efficiency.
2. Polarization conversion:
EPSON's technology has improved the amount of parallel light
that moves through the LCD panels. More light passes through
each LCD because it is polarized without a filter.
Parallel light beam
Non-parallel light beam
EPSON-made Poly-Silicon LCD's are
manufactured to the highest standards.

3. High aperture LCD panels:
The UHA (Ultra High Aperture) has increased the aperture ratio which allows more light through the lens.
EPSON produces the highest aperture LCD's, which are more transmissive.
4. Micro Lens Array:
MLA is a layer of the LCD composed of quartz crystal lenses. Each pixel has a dedicated lens that focuses and
maximizes the throughput of light from the lamp. MLA allows more light to pass through each pixel, more
than twice the light of LCD's of two years ago. (Not included on all EPSON projectors.)
5. "Metal Sandwich" technology:
A light shield of metal between the pixels blocks the light leakage. Cross-talk between pixels is reduced,
resulting in clearer, crisper images. (Not included on all EPSON projectors.)

Image quality—Image clarity
EPSON projectors producte astonishingly clear, sharp images with a combination of these three technologies:
1. High illumination ratios:
The illumination ratio measures the relationship of the darkest spot (the corner) to the brightest spot on the
screen (the center). The higher the ratio, the more uniform the brightness.
2. High contrast ratios :
Contrast ratio measures the difference between the light and dark areas of the image. The higher the ratio the
sharper, more colorful, and more lifelike the images appear.
EPSON projectors produce
vs.
smooth, evenly lit images with
sharp contrast.

3. Panel on Pris m (POP):
This technology allows little or no shift between the LCD panels and the prism, which keeps the pixel alignment
precise and the image sharp and clear.

Image quality—Keystone correction
Many EPSON projectors provide keystone correction, which allows you to correct up to a ±200 tilt while
maintaining the correct aspect ratio.
Without keystone correction
Set up your projector so the lens is
aligned with the bottom of the screen.
With keystone correction
If you can't set the projector up aligned
with the screen, then the keystone
correction will correct the misalignment.

Image quality—EPSON SizeWise™ resizing technology
EPSON's third generation resizing technology supports resolutions from workstations and notebook computers
with:
▲▲▲▲
Clear, sharp text
Virtually no picture content loss
Graphics able to maintain their integrity
Power to handle spreadsheet gridlines and small fonts from any video standard.
EPSON projectors offer different levels of SizeWise technology, depending on the projector's native resolution.

Versatility—Flexible controls
Each EPSON projector can be controlled by the included infrared remote control and control panel. You use
the remote control from virtually any point in the room because the projector has infrared receivers in the front
and back of the projector.
Each remote control and control panel varies, but some of the
universal functions are:
▲▲▲▲
Power
Access on-line help
Access the on-line menu of settings
Volume
▲▲▲
Resize the on-screen image
Mute

Most EPSON projectors are also compatible with RS-232 controllers like CRESTRON™ or AMX™.
▲
RS-232 is a standard for serial digital
communication. It allows the projector to be
remotely controlled either from a dedicated
remote control or a computer.
