Conveniently supports comprehensive wide-format PC signals. Users no longer need to worry about annoying
"Signal not supported" issues, nor must they change the resolution of their wide-format notebook.
Acer EcoProjection Technology (ExtremeECO)
Acer EcoProjection is a complete environment-friendly power management solution that reduces standby power
dramatically. With ExtremeECO feature, projector will automatically enter ExtremeECO mode for saving power if there is
no any signal input. The power consumption can be reduced up to 70%. Also featured in the Acer EcoProjection suite is
Acer ePower Management for customized power-saving configurations.
ColorSafe II
ColorSafe II
Acer projectors featuring ColorSafe are virtually immune to color decay, such as the yellow or green tint on images
displayed by some projectors that have been used for extended periods of time. Acer projectors take advantage of
DLP® technology and also Acer unique color compensation technology on the optical components to guarantee picture
integrity despite prolonged use. The extended lifespan and consistent image quality lower the total cost of ownership and
translate to big savings.
Empowering Technology
Empowering Key
Featured on the remote control or projector control panel, the Empowering Key provides instant access to eProjection
Management (on wireless models only), eView Management, eTimer Management and eOpening Management.
Acer eTimer Management
A digital clock that can be set by the user and displayed onscreen for convenient reference keeps presentations going
at the right pace. Acer eTimer Management also features a visual countdown and alarm, or countdown alone, to warn
the presenter when time is up.
Acer eView Management
Acer eView Management
With Acer eView Management, adjusting projector settings to suit any environment and any type of content is fast and
easy. Eight factory or user-defined presets instantly configure color, brightness and contrast to deliver best-quality
Wall-Color Compensation/Black Board Mode
Wall-Color Compensation
The wall-color compensation feature enables the projector to display colors accurately even when the image is projected
on a colored wall. The user simply has to choose the wall color in the OSD menu, and the projector intelligently
compensates the color of the displayed image.
Acer ePower Management
Acer ePower Management provides quick configuration of power management options, including controls for ECO
Power On/Off, High Altitude mode and Auto Shutdown.
High Altitude Mode
High Altitude Mode
Since air density at high altitudes is low, a projector operating at elevated levels may automatically shut down to protect
itself from overheating. High Altitude mode allows the projector to operate with faster fan speeds, thus preventing any
damage even at higher altitudes.
Top Loading Lamp
Acer Top-Loading Lamp Design
The lamp module is now top-loaded, as opposed to the conventional bottom-loading design. Hence, even when the
projector is ceiling-mounted, the user can easily replace the lamp module without detaching the projector from the ceiling.
Installation Menu
Installation Menu
With the Installation menu, signal input from a notebook is no longer required to enable the OSD menu, making
projector installation on the ceiling faster, easier and more convenient.
2X D-Sub
Dual D-Sub Input
A projector equipped with two sets of D-sub connectors allows dual-PC source input for more flexible connectivity and
instant switching.
Multi-PC Connectivity
Multi-PC Connectivity
A projector equipped with two D-Sub connectors for multiple-PC source input offers more flexible connectivity and
instant switching.
Instant Pack
Instant Pack
If the user is in a hurry to leave, the power cord can be unplugged right after the projector is turned off, without any
resulting damage. There's no need to wait for a cooling period; the user can pack up the projector and leave immediately.
Auto Shutdown
Auto Shutdown
The projector automatically performs a safety shutdown if it does not receive input for a certain time. The shutdown
interval can be changed via the OSD.
Quick Start
Quick Start
The projector starts projecting within 15 seconds after power button being pressed
Quick Detection
Quick Detection
Detects input signals as soon as a source is connected, eliminating time spent signal scanning.
With the intelligent signal priority control, the signal detection time can be reduced dramatically.
PIN Security
PIN Security
A feature that enables projector password control, preventing the projector from unauthorized use, and reducing the
possibility of the projector being stolen.
Digital Zoom and Pan
Digital Zoom and Pan
Digital Zoom and Pan lets the user easily magnify interesting details of displayed content and move the magnified
image to a preferred location.
ECO Mode
ECO Mode
Enable ECO (economic) mode when the ambient light does not necessitate full illumination. ECO mode can extend the
lifespan of lamp, reduce noise and power consumption.
The world leading ExtremeECO technology enables the breakthrough of lamp power control with the capability of
dimming lamp down to 30% of full lamp power. The projector will automatically enter ExtremeECO mode for saving
power if there is no any signal input. With ExtremeECO, the power consumption of the projector can be reduced up to
70% and the lamp life can be extended as well.

Vertical Keystone Correction
40° Vertical Keystone Correction
Elevated projection can result in a "pointing up" or "pointing down" effect. With the keystone correction feature, Acer
projectors correct vertical distortions of up to 40°, so the audience sees a rectangular image rather than one with a wider
top/bottom, even if the projector is placed above or below the screen.
Microsoft Vista® Compliant
Acer projectors are compliant with the most up-to-date Microsoft Vista® operating systems.
Dust Filter
Dust Filter (Optional)
In general, a DLP® projector does not require a dust filter due to its excellent optical structure, but for some very dusty
regions, the detachable dust filter can protect the projector and prevent reduced optical performance caused by dust
3X Color Wheel Rotation Speed
3X Color Wheel Rotation Speed
Acer projectors support PAL video signals, which operate at only 50 Hz frequency. Under this low frequency, projector
increases the speed of the color wheel rotation from 2X (6000 rpm) to 3X (9000 rpm) resulting in consistent colors and
seamless video playback without the rainbow effect.
Closed Captioning
Closed Captioning
With closed captioning, the interpretive text, which indicates the dialogues and non-speech elements, can be displayed
on a video or television simultaneously. A closed captioning device is no longer required. Closed captions assist
comprehension of a video for hard of hearing individuals. It also help for lauguage learning.
Instant Resume
Instant Resume
This advanced feature allows the projector to resume projection right after it has been turned off. Users can turn the
projector on and off any time during the 2-minute shutdown progress, so they don't have to worry about accidentally
turning off the projector or wait for a long cooling period before resuming projection.
Microsoft Windows 7® compliant
Acer projectors are compliant with the most up-to-date Microsoft Windows 7® operating systems.
