Interactive Short Throw Projector
Brighter than expected. We measured the TW610STi at 2937 lumens, or 95% of its 3100 lumen rating. The surprise, however, was how little brightness it lost in interactive mode and eco mode, called Std. Interactive mode came in at 2756 lumens, Std mode at 2535 lumens, and both together at 2369 lumens. That works out to only a 6% brightness drop for interactive mode and 14% for Std mode, with Std mode increasing lamp life from 3000 hours to 4000. Even with both modes on, the TW610STi was easily bright enough in my tests for the 93" screen size to stand up to a moderate level of ambient light. For lower light levels or smaller image sizes, other presets range as low as 981 lumens in Bright lamp mode with interactive mode off.
Acceptable brightness uniformity. The TW610STi scored only 62% for brightness uniformity across the screen, which is typical for short throw projectors. However, this isn't an issue for real world use. Although the difference shows on a solid white screen, the brightest and dimmest areas are far enough apart to hide the difference when the screen is broken up by text or graphics.
Good connectivity. The TW610STi's back panel offers a reasonably full set of connectors, including an HDMI 1.3 port for a computer or video source, two VGA inputs for computers or component video, and both S-Video and composite video ports. Still other ports for image sources include a mini-USB B port for USB display and a USB A port you can use either for connecting Optoma's $29 WiFi dongle or for reading JPG, TIF, BMP GIF, and PNG files directly from a USB key.
Audio ports include three miniplugs for stereo input, stereo output, and a microphone, plus one set of stereo RCA phono plugs paired with the S-video and composite video ports. Also included are a 12V trigger, a pass-through monitor port, a LAN port for both sending images and controlling the projector over a network, an RS232 port for controlling it locally, and a second mini USB port to connect with a computer for interactive mode and for controlling the mouse with the remote.
