Summary: Personal Experience Im on my second BENQ projector. Flat out, they do not last. They will have glitches with the software that tell the system that the bulb is out when it is not. You have to send the unit back to BENQ, and maybe they can fix it. I have to say the people at BENQ are very good though. They have been very helpful. Problems Goes through bulbs. Sometimes they last less than 3 months.
Summary: I bought the BENQ SP890 projector in Oct 2010 from Amazon and have used it 5-7 hrs. a day since then in my Living Room Home Theater and Computer Network. I am on my 2nd lamp which I changed at 3050 hrs. using Economy Mode and it was still bright enough to enjoy all aspects. Now it's Feb 2013 and about time to change the lamp again having 2050 hrs. on it but still working AOK.
Summary: This projector boasts impressive specs by way of resolution and lumens. My experience with the projector was marred by a problem caused by an inherent design flaw - the fans are too close to the enclosure. If the cheap casing shifts, the fans rub up against the side of the case, causing the unit to overheat. This is a poor design and should not be an issue in a $3000 projector! The projector was used in a room with some ambient light and it performed poorly.
Summary: Personal Experience There is nothing like it out there now, folks. Whopping 4000 ANSI lumen of brightness, serial 9-pin RS232 AND RJ-45 wired network connectivity with a graphical web browser control panel for all functions, like with the big dogs, even a confidence video monitor output. Respectable range with a 1.62:1 to 2.43:1 throw ratio using the 1.5x focal range zoom. Lens shift both V/H. Wow!!! Only downside is the manual zoom and manual focus.
