The PLC-XT21 from sanyo is a value-priced, XGA (1024 X 768) resolution projector with an impressive 4000 ANSI lumens, a 1000:1 contrast ratio, along with DVI and Component connectivity. This projector is easy to install using SANYO's exclusive Lens Center design that offers unlimited setup options to meet specific staging requirements with 360-degree position function. To further increase installation convenience, the Up/Down/Left/Right lens shift ensures flawless image projection even in challenging and unusual positions. The Whisper Quiet fan produces an amazing low noise level of only 31 dBA, which is a major advantage in small offices and classrooms. The PLC-XT21 is also equipped with SANYO’s exclusive PJ Network Interface for wired networking where you can monitor the actual picture (with optional module and camera), check status and control projector functions via any web browser. A warning notification can be automatically sent to the registered user’s email whenever the projector encounters warnings such as maintenance needs.
