If you are looking for an economic 3-D projector, check out the Viewsonic PJD6531W, which is Blu ray compatible. This DLP 120 Hz projector is bright at 3200 lumens and can be used in the economy mode in a dark room, thereby extending the lamp life, which is rated at 4,000 hours.
All quality 3-D projectors have 1920 x 1080 resolution. There are some 1280 x 720 projectors on the market, such as the Acer H5360, but I would stay away from this resolution. The price is enticing at under $500.00, but these projectors do not have many of the basic features of the higher resolution projectors, such as an air filter, which can cause a buildup of dust and might lead to a system failure. Some of the low priced 720 projectors utilize a DLP color wheel with a low speed of 4x, causing a “rainbow effect,” which is disturbing to many people.
DLP projectors flicker parts of color to make the image appear complete, whereas LCD uses three panels (one of each primary color), which are projected at the same time. Because of the flashing of the DLP mirrors, some people have a problem seeing artifacts, which appear as a rainbow, when looking at images from a DLP projector that uses a single DLP chip with slow speeds. This effect disappears on the DLP projectors that use 3 chips with speeds of 5x or 6x.
