Verdict

The Optoma HD33 is a home theater projector featuring native Full HD 1080p resolution and a single-chip DLP design with a 1,800 ANSI lumen brightness rating. It is distinguished by its full 3D compatibility over HDMI 1.4a and its use of an RF-based 3D sync system that avoids the line-of-sight issues typical of infrared emitters. Key characteristics include a 10,000:1 dynamic contrast ratio (measured at approximately 4,000:1 native), PureMotion frame interpolation for smooth motion, and an RGBRGB 6-segment color wheel designed to reduce the 'rainbow effect.' Main pros include excellent out-of-the-box grayscale accuracy, a punchy and bright image suitable for 3D or moderate ambient light, and exceptional 3D performance with nearly zero crosstalk at its price point. However, cons include mediocre black level performance that limits dynamic range in 2D, a lack of lens shift and a narrow 1.2:1 zoom that restrict placement flexibility, and a backlit remote control that some users find distractingly bright for dark rooms.
