This site shows the new line-up of Panasonic projectors and provides
detailed information for home use and business use projectors.
The PT-VW431D ranks high in the portable projector category with its high brightness of 4,300 lm.
It also incorporates a variable iris that produces a high contrast of 3,500:1.
This all combines to provide brighter, sharper projection for versatile situations.
Extensive interfaces include an HDMI input terminal, 2 sets of computer (RGB) input terminals, a wired LAN terminal that can be used for DIGITAL LINK, and a serial (RS-232C) terminal for external control. These features support a wide range of system architectures for portable or ceiling-mounted use.
For easier maintenance, you can replace the lamp from the top and the air filter from the side and the back, even after the projector is installed on the ceiling. This eliminates the need to detach the projector from its mounting bracket in ceiling-mounted applications.
