But 92" screen does not do projector a justice, and will probably be too bright. If not limited by the room size, I would go as large as possible.

This seemed to me to be an easier route than trying to get it perfect using any sort of rigid mount.
The 5020UB - it isn’t an issue as the Epson has the biggest lens shift in the business and you can put the PJ almost anywhere and use the lens shift to get the image lined up properly. Lens shift is an optical adjustment so it it has no negative impact on the image quality - it literally moves the lens.
Thank you much for thew information above....I guess I wasn't misunderstanding too badly what the calculators were trying to show me
. A few more questions:
1. What mount would you all recommend if I went the route of the BenQ? I guess with the current screen setup it would require a adjustable pole in order to get that necessary distance offset from the ceiling....
2. I'm leaning towards the BenQ since I'm a novice entry level media room guy. This was a bonus part of the house we bought, and I get to toy with it, since it's "mine" according to my wife
. After the requisitie furniture upgrades and purchases, not much money left to play with to outfit this room, judging by what I'm reading here, in order to turn it into a real theater experience room. Given that, I felt like the Epson would be overkill for me and my purposes. Does anyone have experience with both and can explain what the biggest differences will be between the 2? I don't have a calibration disc or white meter or anything fancy like that, so I'm not a videophile by any means.....
I have experience with both. In fact, I am currently waiting for the release of the 5030UB (early November in the UK) and will be upgrading to that unit.
Really, there is no comparison between these two units. One is an entry level PJ that costs under $1,000, the other is a fairly high spec unit that costs three times as much. If you can run to the 5020UB that will give you advantages all round, with one possible exception (see later).
I'll confine my remarks to difference in PQ between the two, rather than 'mechanical' differences such as lens offset, throw distances etc, as these can be easily checked on one of the PJ comparison sites.
The biggest difference is the black level. The w1070 is average for black level, the 5020UB is way above average. Black is important because it is the 'foundation' of the image. It contributes hugely to 'punch', especially in dark scenes. The w1070 is remarkable for the money - on any scenes other than very dark ones, the PQ is superb. It is pin sharp (DLP PJs are renowned for sharpness) whereas the 5020UB, being a LCD PJ may have convergence issues, where the R, G and B are not fully aligned. The PJ includes a feature to improve convergence. DLP has no convergence issues. The w1070 is very bright, but so is the Epson, so I'd say there isn't too much in it unless you have a huge screen and/or a huge throw distance. The w1070 includes a full CMS so it can be calibrated to ISF standards, which is almost unique at this price level. On any scenes other than the darkest, the w1070 is spectacularly impressive IMO.
So it depends on what you are looking for and what you are prepared to pony up for it. If you want the best PQ you can get for under $3,000 then the Epson is your choice. If you want the best PQ for under $1,000 it's the BenQ. If you think you won’t be too fussy about black levels or about seeing 'dark gray' not 'black' bars when watching a 2.40:1 aspect ratio movie, then you will be very happy with the BenQ. If most of your viewing is TV and sport, you will be delighted with the BenQ. Does that help?
WRT to mounts, just use google or Amazon and see what there is. Measure the distance from the top of your screen to the ceiling and use that as a guide for where the centre of the lens should be, then choose a mount that has flexibility up and down for a few inches, This will enable you to get it spot on. I can't recommend the mount I use because it isn't available in the US. No need to spend a fortune - the BenQ isn't all that heavy. If you go with the Epson, then you can use a mount directly attached to the ceiling and rely on the Epson's huge lens shift adjustability.
