Conference Room Projector
BenQ makes a strong statement with the MX812ST by providing over 3,000 real world lumens and many advanced features in a short throw package. The MX812ST does not compromise image quality to achieve a short throw. The projector provides a sharp, nearly distortion free image with a brightness uniformity comparable to standard lens designs. Packed with features, this projector can run computer-free presentations and includes multiple options for remote control, monitoring and image display. With a street price of around $1,600, it is not the lowest cost XGA resolution projector, but it is a good value when compared with the competition on image performance, brightness and features.
The MX812ST is a good fit for a classroom, as it only needs a small amount of floor space to project a big image. A 100" diagonal image is projected at a distance of just 4 feet. For the classroom, I recommend combining the projector with a mobile cart to help accommodate the fixed lens design. The MX812ST has a relatively large 15% image offset where the image starts above lens center. Using the projector's adjustment feet along the auto keystone feature helped to quickly align the image to the screen. At the maximum keystone setting, I was not able to find any obvious image distortion, even on small font text. At my main office, we have a number of small focus-rooms for groups of about three to four people. This setting was ideal for the MX812ST, as the short throw design allowed us to eliminate the awkward sharing of information using small laptop screens. Placing it on a table about 2 feet from the wall, we were able to project a very bright image about 50" in diagonal. In addition to working well in the small conference room, this projector would be a great way to add a large screen to an executive office.
The short throw of the MX812ST would work well with a ceiling mount installation. Having the projector close to the screen minimizes interference between the presenter and the audience, allowing for a more interactive presentation.
