I am looking for a new projector for my home and I was wondering what the pros and cons of LCD and DLP projectors were. The projector would be in a room with windows so there would be ambient light conditions during the day in case this affects the decision on which type of projector to get.
Answer
Lance gave you info on HDTVs ... not projectors.
DLP and LCD projectors are two of three common technologies (The third is LCoS ... a variation on LCD). At one time DLP was considered to provide better contrast ratio than LCD, but to be more prone to causing visual field issues (so called "rainbow effect" .. caused by the relatively slowly spinning color wheel used in DLP projectors) in susceptible viewers. While LCD projectors were more prone to "screen door effect" ... visible lines between individual pixels (LCoS's big advantage was the absence of "screen door effect").
In modern projectors there is no longer an automatic superiority by DLP projectors re contrast, "rainbow effect" is no longer a concern (due to higher color wheel rate) and with 1080p projectors fairly common, screen door is no longer a significant issue.
While not universally true, LCD projectors tend to have greater mounting flexibility (due to lens offset and greater zoom lens capability) than most DLP projectors, but due to the three LCD panels required are more expensive and more prone to degradation of the LCD panels with time.
That all said, I'd suggest considering the specs and features on the models in your budget range as being more important than whether the projector is based on DLP or LCD (or LCoS) technology.

5800 Lumen DLP Projector vs 6500 LCD projector?
tim m
5800 ANSI Lumen DLP vs 6500 ANSI Lumen LCD large venue projector. Both are hd, both are 16x9, both are same make - different model. This is for purpose of screening independent films in a dark movie theatre. Best quality is what im going for my patrons.
40 foot throw on a 20x30 foot screen. http://www.projectorcentral.com/parts_compare.cfm?pid_1=5939&pid_2=4895&pid_3=5510&remove_compare_list=5764 is the site i was using for the comparison. I know i need something more powerful to be really effective but i've used 6000 lumen projectors in the past and they worked well for what i had in my budget.
These are the two projectors im looking at with a side by side comparison. They will be used to screen independent films off a blu ray player (with a sound system) in a dark movie theatre that seats 500.

Answer
Since lumen ratings are notoriously inaccurate the relatively small difference in brightness isn't very significant. While the rating may be comparable given they are from the same manufacturer brightness varies a lot with how the projector is calibrated, so frankly I'd consider brightness a wash and judge based on other criteria. For example, do you have a preference for one technology over the other, what type of LCD panels, lens zoom range, mechanical vs motorized, noise level, mounting flexibility, does one accept auxiliary lenses or not, warranty, lamp replacement cost, projector cost, etc.
