The CP-WU8440 LCD Projector from Hitachi has 4200 ANSI lumens of projection power at a 3000:1 contrast ratio so it will give you a fine image, even when you can't achieve theater-level darkness.
Its 3LCD, 3-chip technology (the part that creates the image) delivers sharper and brighter pictures with superior grayscale detail. Smooth, seamless color combined with an unparalleled grayscale range delivers incredible detail to every image displayed by the CP-WU8440.
Those images can be in a wide variety of formats. Of course, the CP-WU8440 can project in 720p, 1080i and 1080p high definition. Its international credentials are equally impressive. It can project images in the NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, and SECAM video formats and it has a 100 to 240V AC 50/60Hz power supply.
This projector has a DICOM (Digital Imaging and Communications in Medicine) mode, which reproduces images with an advanced grayscale level. This mode is ideal for viewing grayscale medical images such as X-rays, and for training and educational purposes.
The CP-WU8440 makes your audience's life easier, too. It can display all four closed captioning channels as well as all four text channels from programming sources that provide closed captioning. Closed captioning is useful not only for the hard of hearing but also for people learning English as a second language and for everybody when you have to project in a noisy environment like gyms or trade shows.
If you are working in a noisy environment your CP-WU8440 won't be part of the problem for another reason. Its fan noise is a mere 35 dB in standard mode and in eco mode it runs at 29 dB; literally quieter than a whispered conversation.
