Optoma's TX542-3D is designed to meet the demanding requirements of school districts and businesses. Bright, high contrast images provide easy-to-read text, and the built-in closed captioning decoder displays text from videos that have closed captioning embedded in the signal. Wired networking allows remote management and control of the projector, and a built-in 10-watt speaker system outputs volume required for larger audiences. Optoma backs the TX542-3D with 3 years of Express Replacement Service and a one year lamp warranty to provide added peace of mind.
This thing is as powerful as the sun. We have 4 other projectors, but we no longer use them. This one is amazing. It's also super easy to connect with other projectors (via VGA). You should totally get this! its a must buy camera , good performance and good point and shoot capability
