The XD550U creates a intermediate category in Mitsubishi Electric's line-up of high-performance portable projectors. Placing a focus on greater operation ease, an advanced user-friendly display has been newly added to ensure convenience and simplicity when giving presentations. Other unique features include USB and Internet ports for trouble-free, direct connection to video sources, making these projectors ideal for use in classrooms and meeting rooms.The high 3000lm luminance helps to ensure presentation images are clearly seen without lowering the light in the room. Dark chip3 is designed to the DLP chip line-up. Stray-light processing has been optimized for the optical system, achieving a high contrast of 3000:1. This makes it possible to reproduce sharp, vivid images in which sentences and other characters can be easily read.Fan noise during projector operation can be distracting during a presentation or videoconference. The XD550U projectors operate at a significantly low noise level of only 28 dB (i.e., in "low lamp" mode). As a result, presentations and conferences can be held without distracting projector noise in the background.To use the projector to reproduce images from a computer, a VGA cable, USB cable, LAN cable or commercially available wireless dongle can be used. For displaying images via a LAN, up to four computers can be connected to one projector. The projection screen can be divided into quarters, reproducing all computer screens simultaneously.When using the LAN display function, a USB mouse or USB keyboard can be connected to the projector enabling direct access to a computer utilizing the Internet or other application.
