Verdict

The Optoma HD91 is a Full HD (1080p) home cinema projector featuring a three-LED light source that delivers 1,000 ANSI lumens and an exceptional 500,000:1 contrast ratio. Its key characteristics include a durable LED engine rated for 20,000 hours, a wide 1.9x manual zoom, and horizontal/vertical lens shift for flexible installation. The projector's main pros are its superb colour accuracy, near-instantaneous on/off functionality, and highly quiet operation (23dB in Eco mode). However, notable cons include relatively low brightness levels that require a dark room, mediocre black level depth, and a slow HDMI signal lock time.
