I purchase this projector after read a favorable review in a computer magazine . when I try it out , I fail to properly plug in the power cord all the way . unfortunately it come out when I move the projector to adjust the picture . it take only a few seconds to figure out what have happen and to plug it back in , but the device do not survive lose power . the internal get so hot that component go up in smoke without the fan properly cool down the lamp . Amazon quickly send a replacement unit . I call Acer support the next day to get a opinion on this issue . the question that I ask be : `` what be the expected result when there be a power outage while watch a movie '' . I spend 2 hour on the line with India , without get a answer . the people I speak with recite the manual , which I have already study . the same magazine that originally recommend this projector publish a note a couple of issue later that describe support issue at Acer . the projector require a firmware update because the original firmware do not remember configuration setting . this can only be do at the factory , but customer report that they projector come back without any update do . I like the projector , it be bright and crisp and quiet . I can not comment on the 3d capability - I do not purchase it with the intent to watch 3d content right away , but I want to have the option in the future . Update after 15 month of ownership : I have have the projector store away in its case for most of the time until recently . the lamp have no more than 20 hour of use when I install on the ceiling of my newly finish basement for more frequent use in a home theater setup . three day ago , a white pixel appear . since then , several new white and black pixel appear on a daily basis , and I now have over two dozen . it will soon be no longer usable if pixel keep go out at this rate . the basement be clean , air-conditioned , and a low-dust environment . from what I read , replace the DLP chip be cost-prohibitive and the projector will become e-waste ater a little over a year with less than 100 hour of use . I be downgrade it to one star . my picture look very much like the one show in this thread : -lrb- ... -rrb- and base on the number of post there be seem to I that this be not a unusual problem with Acer projector .
