A great pick for business use, this projector produces bright images and has good color accuracy.
The Optoma HD66 is the cheaper projector, priced at about $630. But it also has less projection power and lower resolution, so the extra power and resolution of the Canon might be worth the extra outlay.
Blacks & Whites
Both projectors can bring a lot of light to play: we measured both at about 2700 lumens in their brightest mode. But both have the same issue of the modes that provide the best color accuracy are much dimmer.
Both projectors scored well in our color tests, producing consistent whites and doing a good job of reproducing subtle color changes. These tests are carried out in our calibrated settings, which look for color performance over brightness, and both projectors produced images in this mode that are much dimmer than their brightest modes.
Both projectors produced acceptably smooth motion, although the DLP-based Optoma HD66 was somewhat prone to producing occasional color fringes on fast moving objects (called the DLP rainbow effect)
The Optoma HD66 has only a short range 1.1x zoom lens, which means it can only be placed within a limited range of distances to fill the screen. The Canon has a zoom lens with a longer range, which makes it more flexible for business and other non-permanent placement usage.
The Canon provides a wider range and number of connections, but the Optoma does include a HDMI port, which makes it easier to connect to devices such as Blu-ray players.
