"I am trying to investigate using projectors in our distance learning labs rather than the TV monitors that we currently have. The problem is, when I look at the specs I have no reference point to go by (knowing nothing of projectors). So, if I look at the lumens I don't know what is bright enough for a lighted classroom, etc.
I can figure out how large the area projected from a given distance is, and that kind of "room specific" parameter. What I need to know is minimum resolution, brightness, and possibly the more robust brands to look at for a classroom environment.
Another angle may be cost of maintenance. We have a $10k HD projector in our student center for "movie night" and other activities, and I just found out they go through about 2 $300 bulbs per year. That times the 13 or so rooms I intend to convert gets a little pricey.
BTW, these rooms will prob be going to the Vtel Vista codecs, so compatability with that is a must.
Thanks"
