Last Update October 24, 1996
Of course, active matrix costs more then passive matrix (see costs section below).
Until very recently, most LCD projectors were limited to 640x480 resolution and could only do 800x600 in a compress and highly pixelated mode. Now, there are two very good true 800x600 projectors that we have evaluated (see below). The higher resolution units do not yet exist, except for one 1280x1024 fixed focal length LCD projector made by ASK. This has a list price of about $17,000.
3M has also come out with the model 8650 which is a true 800x600 unit which has 1000 ansi-lumens of brightness. This is a beautiful projector if you can afford it. Educational price is $7500. We are also a little wary of buying this resolution if the 1024x768's aren't too far behind.
Update: Well the 1024x768 LCD projection market is still not here as of Sept. 1997. In the mean time there are several impressive 800x600 UNITS out there including the 3M8640 but we definitely like the SHARP XG-NV1U Notevision - extremely crisp display and nice and portable. Highly recommended.
Although prices continue to vary and in general are coming down here is a rough breakdown from the bottom up of the kind of pricing that is available at the educational discount level.
