This is the best around $500 movie cinema projector for a low budget. It costs less than the under $1000 options that are often mentioned, but delivers a comparable picture. It works well both in the office (presenting) and at home (watching movies).

Pros
Pro Very good picture quality
BenQ TH670 has a resolution of 1920x1080, producing a detailed Full HD picture. It has a white brightness of 3000 lumens so it's bright enough to deal with ambient light in a family room.
Compared to other inexpensive HD projectors, the TH670 has the best contrast. A contrast ratio of 10 000:1 means there is a reasonably large difference between the blacks and whites this BenQ projects on the screen. This helps create a life-like picture. The contrast ratio (as for TH670’s competitors) is boosted by BrilliantColor technology. Unlike its competitors, the BrilliantColor can be disabled. This lets you choose between a high contrast or better colors, depending on the content.
