Ease of installation
Corner keystone correction enables angled projection
All you need to do is designate for points as the corner of the projected image,
and this function easily carries out horizontal and vertical keystone correction.
Curved screen correction
Barrel and pincushion distortions are easily corrected when projecting
onto a curved screen.
Easy remote monitoring and control over a LAN
Web browser on a computer connected through a wired LAN system lets you remotely operate projectors and check their status.
In addition, Multi Monitoring and Control Software is available for monitoring and controlling multiple Panasonic projectors from a single PC.
The wired LAN terminal is compatible with PJLink™ (class1), an open protocol that is used by many manufacturers, to enable integrated control of systems that contain different brands of projectors.
Easy lamp and air filter replacement simplifies maintenance
For easier maintenance, you can replace the lamp from the top and the air filter from the side, 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.
