BenQ PE8720 projector features

Highest picture quality

This single Dark Chip 3 DLP™ projector provides excellent picture quality due to its high resolution, 
excellent home theatre brightness, super high contrast ratio, vivid color and rich gray-scale reproduction.

Super-high contrast ratio

This projector utilizes a motorized aperture C.A.T. lens to achieve a contrast ratio of at least 4400:1 (and 
up to 6200:1 in High Contrast mode). 

Vivid color reproduction

This projector features an 8-segment color wheel to produce realistic color depth and range unattainable 
with lesser segment color wheels. 

Rich gray-scale

When viewed in a darkened environment, the automatic gamma control provides excellent gray-scale 
display which reveals details in shadows and in night or darkened scenes.

Dynamic performance

This model projector features a refresh rate of up to 300 Hz which provides excellent dynamic 
performance and eliminates the 'color flicker' or 'rainbow effect' associated with DL projectors.

Extra-low noise operation

This projector's unique cooling system design prevents unnecessary fan noise, and is rated at less than 
25dB in normal mode and a low 23 dB when in Whisper mode.

Sealed optical engine

The optical engine uses a high-quality 1:1.35x lens for maximizing optical performance. The sealed light 
path prevents light leakage, enhancing your viewing experience in darkened viewing environments, and 
prevents the dirtying of the optical path which can cause annoying blurring or spots in the projected 
image. 

Motorized lens shift, focus and zoom

The remote control can be used to adjust vertical lens shift, picture focus, and picture zoom size, all  from 
the comfort of your armchair, which is particularly useful if the projector has been ceiling mounted and 
accessibility to its panel controls is difficult or awkward.

Wide variety of inputs and video formats

The projector supports a wide variety of inputs for connection to your video and PC equipment, 
including component video, S-Video, and composite video, as well as HDMI, RGBHD, and an output 
trigger for connection to automated screen and environment lighting systems. 

Digital TV compatibility

The projector is compatible with Standard Definition TV (SDTV) 480i, 480p, 576i, and High Definition 
TV (HDTV) 576p, 720p and 1080i formats, with the 720p format providing a true 1:1 image 
reproduction. 

De-interlacing (with NTSC 3:2 pull-down)

Using BenQ's proprietary de-interlacing technology utilizing Farouda DCDi processing, this projector 
provides excellent scaling and film-to-video (NTSC 3:2 pull-down) conversion for the most artifact-free 
images possible.

PIP/POP function

The Picture-In-Picture (PIP) and Picture-On-Picture (POP) functions allow you to display two inputs 
on the screen at the same time.
