Remarkable 5000 lm brightness & high contrast of 3000:1 make projections crisp, clear & stunning, even in large lecture hall settings. Need to present in a brightly lit room? No problem with the DLP projector, because projections remain vibrant & clearly visible whether the lights are up or dimmed. The Mitsubishi Electric color wheel & Brilliant Color guarantee that images are rich & true-to-life. This projector installs virtually anywhere. Simply open the top cover & use the shift-adjustment toggle to manually shift the lens vertically. A significantly low noise level of only 28 d B in low mode ensures that the presenters voice comes across loud & clear without a distracting fan noise in the background. When using the LAN display function, a USB (Universal Serial Bus) mouse or USB (Universal Serial Bus) keyboard can be connected to the projector, making direct access to a computer using the Internet or other application possible.
