I'm trying to decide between the Hitachi PJTX100 and the Panasonic AE700. But first a bit of history... I used to share a house with a friend who owned a Sanyo Z2. I always enjoyed watching movies on it, but always felt it was (i) a bit murky in dark scenes (e.g. pirates of the caribbean) and (ii) too dim for the screen size I preferred (about 2.5m wide). The distance from projector to screen has to be 4.5m in my flat, which is why I have discounted the Z3 (because the min. screen width for the Z3 at this distance is around 2.5m, and since this has the same lumens as the Z2, I don't think it will be bright enough). I've also discounted the InFocus LCD model as it's more expensive and also quite nosiy (I definitely want something quiet to run alongside my ultraquiet HTPC). So, in my price range (absolutely no more than £1200) that leaves the brighter AE700 and TX100 (I have ruled out DLP because I see lots of rainbows - even on fast colourwheel projectors - and always end up with a headache - it feels like a vice is being tightened around my head. They also don't have lens shift for both axes, which is essential for my room layout). Viewing will be via HTPC via DVI (digital or analogue, depending on which gives the best picture quality). Screen willl be a matt white wall for now - I can't afford a screen yet. So, has anyone had extended periods with *both* of these projectors? If so, what are your impressions? Worries I have about the TX100 are the reports of sudden bulb dimming (I'm assuming this isn't a macrovision issue) and loud fan noise (it seems like a lottery as to whether you get a quiet one or not). The thing that makes me like TX100 is its tweakability - the menus seem very comprehensive, allowing custom gamma settings (akin to a 5 band graphic equalizer) which I assume will help tune the projector for better shadow detail - and once you access the service menu, there are many parameters which can be adjusted to reduce vertical banding and colour uniformity. It's also very, very bright indeed (according to reviews), so it will go BIG! (from my long term experience with the Z2, big is very much something I require). Worries I have about the AE700 (I'm assuming that by the time I get around to buying, new AE700s will have version 1.07 firmware) is vertical banding (it seems like panasonic has a reputation for having the worst vertical banding of the epson panel using porjectors) and the lack of tweakability (compared to the TX100) for minimising it (along with colour uniformity tuning). Things that appeal about the AE700 are the smoothscreen technology, the dynamic iris used to increase contrast and the quietness. So, for those who have known both of these projectors, which would you say had the better shadow detail? (this is my main bugbear). Black level? Picture quality in general? Considering that I want an image between 2.5 and 2.8m wide, would the panasonic be able to handle this (in terms of brightness)? If not, perhaps I should sit closer to the screen... Any other comments would be greatly appreciated.
