In my experience, LCD gives a
more accurate picture of the image reflected on your PC.
If you are giving (for instance) power point presentations,
then you will benefit from the accuracy of LCD, as it better
reflects what you've created. This benefit is
countered by DLP's ablility to give brighter whites and
blacker blacks. DLP projectors offer a picture that is
driven by a circular reflector that throws a single ray
image onto your screen. It tends to run a little
hotter (thus the lamps tend to burn faster), so the cooling
down process seems to be longer (of course this varies by
manufacturer). In my opinion, if you are going to be
staring at your projected image for an extended period of
time, or if you are going to be starring at your image at a
close range (ex. using an interactive whiteboard or in a
small room in your home) then you will probably benefit more
from an LCD projector. If you simply want the
brightest image, then you should look closer at the DLP
projectors. DPL has had tons of recent marketing and
is making an impressive impression in the industry.
The best way to make this decision is to test both of the
technologies for yourself (at a local dealer's location),
and please, once again, keep in mind the cost of replacement
lamps. If a projector runs hotter then it burns it's
bulb faster. Also, if you would like the ability to
turn off your projector then you would prefer a cooler
technology. Again, for projector lamp information,
