Subj : Re: Power Point To : JEFF GUERDAT From : JAY EMRIE Date : Fri Sep 16 2005 01:36 pm Jeff, after replying earlier to this message I got to thinking. I have an OLD InFocus LitePro LCD 580 projector. Here are some of its specs: Resolution - 640 x 480 VGA with intelligent compression for 800 x 600 - Higher resolutions will be cropped. Keystone correction for only 13ø 300:1 contrast ratio 250 lumens I know that there are far superior LCD/DLP projectors out there.An Infocus LP70 for example: 2000 lumens - 1100:1 contrast ratio - 1024 x 768 native resolution - keystone correction +/- 15ø - 1500 brightness. These specs are far better than the 580 I have. We just do not know which might be the best over all for our needs. Those are just sample specs for one projector. There probably are some that are considerably better. That is what we are trying to determine. We want to compare both the specs and cost to try to determine which is the best for us - capability AND coastwise.
