there be two main reason I buy this projector : 1 . the increase in resolution over my SVGA projector . 2 . the horizontal keystone correction so I would not have to have the projector perfectly square . the projector succeed in the resolution department as I can now easily read small text in the Netflix movie description . however , the horizontal slide correction do not work anywhere near as well as I have hope . it do function and help some but no where near the correction capability of my Uncle 's Panasonic pt-ae700u with lens shift . grant the Panasonic model be considerably higher price than this projector when it come out , I still feel Epson 's horizontal correction capability be overexaggerate in the diagram provide in the description . if you do not care about this feature this be easily a four star projector for the price -lrb- can not really knock it for be 720p instead of 1080p in this price range -rrb- . the minus one star if for a fan that be a bit louder than my old SVGA projector that be similar in brightness and rate at 2600 lumen , so the brightness be not the only factor in increase fan noise . ultimately , this be a upgrade to my previous projector and be probably a fair deal for the price but I feel it do not quite live up to some of it be claim .
