The Epson is well rounded for HDTV and sports. True, its maximum under 1400 lumens is only 2/3 of the BenQ (the brightest), but still healthy and one of the brighter projectors (in "brightest mode) in the entire review. Very good blacks get the job done for movies as well, but defintely work on those darker Discovery HD scenes. Hey, I pulled down my JVC this Superbowl, and put up the more expensive Epson UB (same brightness, mostly same everything, but black levels - which in this case didn't matter), for our annual party.
If I have one complaint about the Epson for sports and all digital content from HDTV and it's one shared with every LCoS and LCD projector under $9990 - and that is, it could be a touch sharper.
There would have been no noticeable difference between the 8100 and the UB for the entire day's viewing. I worked out great. It filled my screen, with some shades partially open. My JVC would have required them all closed to be comparable. Made for a much more fun party, having those lumens. BTW, in the 2nd half, when the sun is no longer coming into the room, I changed the Epson Home Cinema 8100 from Dynamic (brightest) to LivingRoom mode (2nd brightest, with still about 1100 lumens. With that mode, color became very good, (get's rid of some excess green).
Not that my audience would notice! Hey, it's a key reason I like the 8100, it's versatile, and pretty bright when you need it.
