Sincere thanks to all respondents. The information and suggestions provided regarding the projection of digital images in a large lecture hall are much appreciated and summarized below.It appears that affordable monitors or projectors are not yet available to display high-quality images in a large lecture hall and it is difficult to maintain consistency with different output devices. However, technological advancement in this area seems promising (see the Teaxas Instruments WWW site listed last below) and the costs should go down. The following are the best solutions suggested to date.
LCD (liquid crystal display) panels seem to be most commonly used; they are improving in quality, but are still limited. "Near photographic" and "pretty good" were terms used to describe the images projected using this technology which makes me wonder if this would be high enough quality to satisfy art history faculty? These projectors range in price from $6,000-10,000. Among the brands recommended were the following: Sharp XG-E1000U, Epson ELP 3000, Eiki, and GE.
There are other categories of higher-end projectors and compact polysilicon models. The highest recommendation in the former category was the Sony VPH-1292Q data projector (costing approximately $30,000). The latter top three performers (according to the article mentioned below) are the In-Focus Lite PRO 580, Hitachi CP-L500, and the Polaroid Polaview 105 the first of which came highly recommended (costing approximately $10,000).
HDTV (high definition television) provides the best available projected images in the $60,000-80,000 range. A specific brand or model has not yet been mentioned and I have not yet had time to research this. I will forward anything exciting that may turn up, but doubt if this is affordable for most of us.
Dick Harrington, from the Library of Virginia, recommended the January 2, 1996 issue of NEWMEDIA, p. 61, for a review of 18 projectors.
Kathy Lintault, from California State University, San Bernardino, recommended several WWW sites to explore (searching on "smart classroom"): http://classrooms.com/ http://www.nwu.edu/classrooms/ http://charlotte.acns.nwu.edu/gretchen/ http://www.cis.hawaii.edu/CurrentNews/latenews.html http://www.columbia.edu/acis/classrooms/ http://www.ti.com/dlp/docs/Companies.HTML
If anyone has additional information or if you would like to add to or clarify this summary, please feel free as I am a mere novice when it comes to digital projection. I, for one, can't seem to get enough information or suggestions. There were seven responses in total which makes me wonder how many people out there are actually projecting digital images in large classrooms? Any more news would be appreciated and thanks again to those who responded.
