Conclusion: Rated at a bright 4,000 lumens, the 6.5-pound Optoma TW762 business projector manages to be both bright enough for a mid- to large-size conference room or classroom and portable enough to carry.
Pros: Bright, with a 4,000 lumen rating, yet light and portable. HDMI port. 3D-ready. 1.2x zoom lens.
Cons: Although data image quality is certainly acceptable, it's a touch below top tier.
