best projector lens shift image
Roberto
i want a projector that its worth it but at the same time economic, i want it for a standard not so bright room, and I be using it as a home theater projector.
So what some considerations that i have to keep in mind, and where can i get these things?
thanks for your help xD
btw when i say cheap im thinking about 200ish more or less, although idk if its good enough
Answer
Projectors are the best way to get a big image, but they are not for everyone.
The lowest price you are likely to find for a reasonable quality projector suitable for home theater use is about $500. You may find a used one or a end of line or refurbished one for a bit less, but realistically expect to pay $500+. The lamp alone usually costs $300 or more and must be replaced every 3000 hrs or so (so be careful with used projectors .. the lamp may be almost dead).
In terms of what to look for ... resolution (look for 720p or better e.g. 1024x768, 1280x720) and contrast ratio (i.e. at least 2000:1). Most inexpensive projectors will be lower resolution and have low contrast ratio (e.g. 4-600:1). You can probably live with lower resolution (if you keep image size under 70-90"), but low contrast means a washed out picture. Better projectors have dynamic CR's over 50,000:1.
Brightness is another critieria that matters, but since you get the best image in a dark room, anything over 1000 ANSI lumens is plenty.
A wide range (e/g/ 1.7:1+) zoom lens and lens shift is nice, but adds significantly to cost.

Difference betweem a Home Projecter and a Data Proector?

Guys, 2 projector from the same brand and same specifications are priced differently because one is a data projector and other is a home projector. Why so, what is the difference. Now for example Benq MP 611C and Benq W100, both are priced very differently. Please explain.
Answer
There are different requirements for a business and video / home theatre projector. The latter is more demanding in a number of ways -- particulalry re. resolution, expected colour accuracy, fan noise level, and contrast ratio -- and delivering this can result in higher costs (and a higher price).
But let's look at your example. The specs are similar in many respects, but are far from the same.
Both are DLP based (although the 7 segement color wheel on the W100 (vs 5 on the 611C) may be indicative of better colour performance, and the faster spin rate is less likely to lead to artifacts (Rainbow effect). Fan noise is very similar, at least in eco mode (24 db vs 25 db). Weight and size are similar. Neither have lens shift, and lens appear comparable.
But bigger differences exist in resolution and aspect ratio (4:3, 800x600 for the 611c vs 16:9, 854x480 for the 100). Contrast ratio is marginally, but perhaps significantly, higher (2500:1 vs 2000:1) but brightness is much lower (1300 vs 2100 (the latter is typical of business projectors that must be able to work in a fairly bright room)) on the 100 vs the 611c.
The two models are plainly aimed at two separate markets, but I agree there is little to justify the apparent price difference (MSLP of $750 vs $1200), but the current dealer prices (See links below and follow the "current dealer prices" link on each page) are almost identical $586 vs $595 suggesting the marketplace agrees with you.
It might also be worth considering that price of projectors (particularly home theatre models) has been decreasing quickly in the last year, therefore the Feb 2007 shipping date for the 611c (MSRP $749, business model) and the July 2006 shipping date for the 100 (MSRP $1199, HT model) may be at least partially responsible for the apparent price difference.
Finally, while maybe not the case here, in general manufacturers will anticipate that consumers will be willing to pay a premium for relatively small feature differences. This is commonly seen in many areas (e.g. cars, cameras, stereo equipment (e.g. A/V receivers)). A base model will be one price and the next model up will be significantly more expensive because of some attractive feature that doesn't actually justify the price differential.
Hope this helps.
