The greatest strengths of the e-projectors from Sony are performance, being user friendly & being economic. The VPL-EX145 offers these benefits along with outstanding image quality with low operating costs. The throw ratio 1.3 to 1.82 & 1.3-fold optical zoom, enable the VPL-EX145 to install in a variety of facilities & use any existing ceiling mounts again. With a single press of the new Eco-Mode button on the projector housing (or on the supplied remote control) enables users to easily switch to energy saving mode. The VPL-EX145 is equipped with three brightness modes (High, Medium & Low), with which the user can adjust the light output & power consumption of the projector to the ambient conditions.
