When I was at university my classes had projectors putting up a computer display on a huge screen. I'm not sure of the size, but the picture looked great.

I don't know much about projectors and am having trouble finding information on them online so I'm coming to you guys again to find the straight dope

What sort of resolutions to they put out?
What angle to they project at?
How far will they project?

I know that they all have different ratings but does anyone know of some specific examples of good ones and what they cost?

Thank you,

look at google under data projectors, some are in the 600 dolar range thru to 3000 I think

Want a cheap projector?

Get yourself an old OHP and a TFT monitor and build one yourself!
