Panasonic technology assures sharp and comfortably viewed images even with the blinds open by enhancing fine details (particularly in dark areas of the image) that are normally difficult to see in bright rooms. A built-in sensor measures ambient light while Daylight View Basic adjusts halftone color and brightness to suit ambient illumination. Insert a USB memory device into the projector port. In less than a minute, configuration setting files and an application are copied. Plug the USB memory device into your PC, click the player icon, and transmit video and stills wirelessly to the projector - no software or network setup required. DIGITAL LINK transmits uncompressed video, audio, and control commands through a single CAT 5e or higher STP cable. You don't need a computer to start presenting - just insert a USB memory device containing media and start projecting straight away. This includes Full HD video as well as still images. A simple Graphical User Interface (GUI) assures a smooth and stress-free presentation.
