Optoma projector launched entry-level (model: EP720) for home entertainment purposes. Weighing only 2Kg it offers SVGA (800 × 600) resolution, 2200 ANSI lumen brightness, contrast ratio of 2000:1, and built-in speaker, if you do not have external speakers for hook activity. If you want to build low-cost Home Theatre these low-cost projectors, decent 5.1 Home Theatre speaker system and DVD player will do a fair job.
