I am looking to purchase some new or refurbished projectors for the school I work in. In looking some over I have found three questions that I have.
1. Do Lumens matter? If so, how?
2. Is there any significance to ANSI Lumens?
3. Most projectors are listed as SVGA, but a few are XGA. I assume XGA is a more advanced offering, but what is the difference, if any?
Thanks.
