You could do what you want with the fabric, but by the time you bought a used Stewart frame and new replacement fabric, you might as well buy a Stewart screen, since you would most likely have the same money in it.
Yeah I read that wrong, it seems. It had sounded like you had to sell the original material (since one would keep the frame) in order to get the newer material for the same Stewart frame.

Upgrading from a TW3600 which had to be swapped out a number of times due to bad convergence. Does the digital adjustment eliminate the problem?

Considering this alongside the new Sony HW40es which has lcos panel alignment plus costs a lot less in UK.

Thanks
sorry to quote myself, but anyone got answer for me

I'm using a Vapex tab-tensioned 100 inch electronic drop down screen. It has a 1:1 gain and I feel it's a terrific bargain. I personally don't see SDE from my seating position and have to get pretty close to the screen to see the individual pixels, but others have had some issues with it. It has got to be based on the throw distance and seating distance, I would imagine.

That's a good point to mention. On my setup at 1080P I don't see individual pixels (which I would think is similar to SDE-range) until I'm standing about five or six feet from the screen, about a third of the correct seating distance, far far too close for useful viewing of any sort. I have normal 20/20 vision, for what it's worth.

The only comment I can offer is that I looked at the alignment adjustment screens and mine seemed to be pretty dead-on correct straight out of the box. If I walked right up to the screen, literally two or three feet away, I could see a faint vertical offset on the red on *some* of the grid lines, but it vanished at four or five feet, and is definitely not visible at seating distances of 16 to 18 feet.

Not sure if that helps at all or not.

Of course if you have 20:15 vision you will see SDE a little further back from the screen than someone with 20:20. I agree that SDE should not be an real world issue for the vast majority of people when using a 1080p 3LCD projector and with any reasonable viewing distance. I've used a couple of 1080p Epson projectors in my home theater, as well as a JVC LCoS, and have not seen SDE from my normal viewing distance (120" screen with about a 12 ft. viewing distance).

Only for very small values of "a little further back".

20/20 means your vision is normal at 20 feet, whereas 20/15 means you see what a normal person would see at 15 feet instead of 20 -- a 25% improvement.

So if you see SDE at about 5 feet, for example, that means a person with 20/15 would see it at about 6 feet. Not a significant factor relative to normal seating distances.

I have read that the best human vision ever recorded was 20/8, a 60% improvement versus normal vision. As long as seating position is more than about 8 or 9 feet away, even that person probably shouldn't be expected to see SDE on a decent quality setup.

Hello all. I have a few questions for you guys. I'm getting ready to order the Epson 5030 and will be projecting onto a 120" diagonal 16:9 Seymour retractable AT screen that will drop down in front of my speakers. I'm in the process of doing the layout in my living room. I'll be setting 12' away from the screen and the projector will be mounted 3-4' directly overhead. I originally had intentions of using a low profile ceiling mount (that would put it ~ 3' above my head). Now I'm thinking it might cool if I put it in the column directly above that (I've attached pics to show this). Although, there may be a couple of problems with this. First would be space above the top of projector for enough ventilation to stay cool. Front, back, and sides would be fine I think because the front of the column would be totally open (for the air intake and output on the front of projector) as well as the back of the column and I could make it as wide as needed for space on the sides. The only thing that would be pretty tight would be the top. Projector dimensions are: 18.3"W x 6.2"H (with feet) x 15.5"D and column dimensions are 8.5" H x 19"D. I don't think the column is load barring/supporting of the ceiling (2 story with loft above) but depending on how the bracing is set up I know I will not have that much height to work with unless I can make some space above the column. Also having a sturdy platform the projector to set on will take up some space.

If that all worked out and the projector would stay cool enough, the next possible problem would be enough vertical lens shift (without using keystone) to have the top of the 120" diagonal image 13" from the top of the ceiling. I read a 5030 review the other day saying that from the middle of the lens to the top of a 100" diagonal image could go down as far as 22.5". That's quite a bit of vertical lens shift so I think it would go down far enough for my 120". Do you guys know if PQ or lumens is effected when approaching maximum lens shift? The last possible problem would be some of the projected light hitting the tip of the fan blade if it was on (would be close I think).

The wife definitely likes the idea of the projector being mostly hidden with a cleaner look. I think it would be cool as well. I'm really into 3D so I'm sure I'll be watching a lot with the Dynamic 3D mode (for the brightest possible image) with the fan at its noisiest/fastest. So putting the projector in the column would put it about a foot higher above my head than with a ceiling mount to the bottom of the column. That and the somewhat enclosed projector would probably cut down a little bit on the high speed fan noise. Do you guys think this is a good idea and would work or should I just stick with the original plan and use the ceiling mount to mount to bottom side of the column?

One other question ...sorry for the long winded post. I'm ready to purchase this projector soon but keep trying to talk myself into waiting to see if Epson comes out with a 5040 soon after CEDIA. My screen wont be here for 3-4 weeks anyway. I'm pretty much maxed out on my budget but may be able to swing a few hundred more dollars if its around $2700 ish. Do you guys think it would be worth waiting to see? If so what do you think the earliest to purchase would be (I'm thinking maybe end of October possibly)? I'm so excited I don't know if I can wait that long

Thanks,
Shelby

I'm by no means an expert but I wanted to comment on these three points.

First, ventilation is through the front only, both in and out. However, the top should be accessible to your hand to adjust lens shift, zoom, and focus. There are no vents anywhere but the front.

The lens shift on this is definitely great. I read that it automatically compensates for the minimal keystoning that is unavoidable with lens shift. I couldn't see it and I'm using about a third of the full range of vertical shift. There is also a chart I saw somewhere online (sorry, can't find it) that shows lumen loss at maximum shift. I want to say it was something like 12% but that's off the top of my head and might be totally wrong. Search around, you can probably dig it up. Here again, I'm using about a third of the v-shift range and I'm amazed at how bright this thing is.

As for waiting, I think I read that Epson was one of the only companies to roll out a major update last year -- my guess is they'd sit back and ride this one out while everybody else plays catch-up.

On my last PJ, I kept waiting and waiting for The Next Big Thing -- there will always be a Next Big Thing. The 5030UB is pretty awesome -- buy it and enjoy it, I say.

You are most likely going to run into issues if you attempt to cut a space out for the projector. First, the height of the column is barely enough to house a 5030. Secondly, there are most likely 2x4 cross-members there, taking 1 3/4" away from that available space. Lastly, the section is undoubtedly load bearing, meaning you cannot modify it in any way.

My recommendation is to purchase a high quality low profile mount and take the easier route.

Here's an excellent mount that you can take a look at. It offers micro adjustments.

I have a very long room, so it it best to have it set up where its at mid zoom, all the way open, or closed mostly? I would guess its best to have it all the way open as you are using the bulb anyways, its not like the bulb dims if you have it closed down more? So what do you guys think?

You always want the shortest throw that will fill your screen.

If you need maximum brightness yes, but there are downsides (image quality, depth of field...).

I should say "I" always want the shortest throw ... admitted light-cannon addict here. I defer to the experts, a big bright picture makes me grin like an idiot and I'm done.

Can you please elaborate on this? Make it as long as you need. Also talk about the wide open mid and closed please

^ The difference in brightness between the ends of the zoom range is often measured by the review sites. It's not the same amount for all projectors, but it's always brighter at the short throw end (projector as close as possible to the screen for a given image size).

What's harder to quantify are the other effects. Depth of field is reduced with short throw which makes it harder to achieve perfect focus (and can make it impossible to get perfect focus over the entire screen if things aren't perfectly aligned). Image contrast is also reduced with a shorter throw, and any aberrations caused by imperfect optics will be more noticable (but there won't necessarily be a big difference).

If you absolutely need the max brightness then go for the closest mounting position, otherwise you might want to mount it a bit further back. I can't really quantify it.
