The Japanese manufacturer Mitsubishi has recently released two portable high-definition projector models - the WD620U and the FD630U.

The projectors weigh eight pounds each and come complete with contrast ratios of 2,000:1 and brightness of 4,000 lumens. The projectors do not disappoint on features and both include 10-watt speakers with audio-mixing capabilities, along with a visual PA system and closed captioning decoders.

The devices use DLP chipsets with inbuilt Texas Instruments BrilliantColor technology.
They also come with built-in RJ-45 ports for remote operation and management over LAN, WAN, or the Internet. This uses Mitsubishi's ProjectorView Global+ technology allowing users to monitor the status of multiple projectors and turn off the projectors remotely. These additional features make the projectors ideal for use in training and instruction scenarios, as well as for teaching and consultation.

Other useful features for these markets include the audio mix capability, which enables users to project audio from two separate sources and adjust the levels of volume from each input to the built-in speakers. These features help speakers using the projector as a presentation aid to orally interject during the presentation, and still be heard over the audio.
