Optoma Technology TW631-3D Multimedia Projector

The Optoma TW631-3D Multimedia Projector packs a lot of advanced features backed with strong specs and cutting-edge technology into a surprisingly affordable package. Its 3500 lumens of projection power combined with its 10,000:1 contrast ratio and WXGA (1280 x 768) resolution means it will provide a tack-sharp, vivid image in medium to large rooms, even those with high ambient light challenges.

Another of the TW631-3D's key features is its Texas Instruments DMD DLP chip. This single 0.65" DC3 DMD DLP processes not just the three primary colors that all other chips work on, (red, green and blue), but also their complements: cyan, magenta and yellow. DLP chips increase the brightness of colors by 50 percent versus DLP chips without it. An added advantage of this chip is that it requires no filter that has to be periodically cleaned and replaced, an operation that can be risky in ceiling mounted installations.

The TW631-3D as its name suggests is 3D capable. Thanks to DLP link technology 3D content can be viewed with compatible 3D glasses and a 3D equipped computer. Studies show that viewers retain 3D screened information more than 2D. Imagine adding this immersive element to classes or presentations.

The projector's wide connectivity includes HDMI, two VGA inputs, a RS-232 and a USB for mouse control. An RJ-45 connector is also included for control of the projector or several of them, remotely over a network. As far as audio is concerned, the 7W sound system eliminates the need for external speakers in most cases.

The TW631-3D is world-ready thanks to its auto-switching 100 to 240 V AC power supply and compatibility with NTSC, PAL and SECAM color systems. It's also compatible with PC and Mac resolution and frequency combinations so it's ideal for laptop-based business presentations.

Lastly, once you've gotten used to the TW631-3D's advanced features you wouldn't want it to take an unannounced leave of the premises. There's a control panel lock, password protection and a security bar to prevent that from happening.
