I'm in the market for a good, affordable LCD projector. Suggestions
on what to get or stay away from are appreciated! Must be 1024x768
minimum.
I found this one earlier today: http://tinyurl.com/s7wcx
My GM found an Epson that's about $200 more and has over 2000 lumens.
Would I notice a difference between 1500 and 2000 or are we splitting
hairs at that point?
I don't know whether it is a good idea to point out to you the inverse
square law here: if you wanted to achieve the same screen brightness
with the projector 50% further from the screen, the projector would need
an output (in lumens) 2.25x greater (1.5 x 1.5 = 2.25). You can do the
calculation in reverse to calculate how much further away from the
screen the more powerful projector can be and still achieve the same
screen brightness. These calculations assume that you are using the
same focal length of lens and that the lenses are of comparable optical
quality.
