What happens is you have two patterns (projector SDE and screen fabric) that are very identical but not lined up perfectly.

hmm, so you suggest de focusing may help? Or trying to move the screen/projector around to line up?

A high resolution camera will always show the patterns especially if you zoom in. The question is whether the patterns are visible to the naked eye at the normal viewing distance.

It will be hard to line up. Actually being too close to lined up is the problem. If they had the pattern at an angle, you wouldn't have the problem.
Defocusing the projector reduces one of the pattern.

The pattern should be cut at an angle. I had confirmed that with ST when I was inquiring about purchasing from them.

Yes, the fabric pattern should be cut at an angle to avoid moire pattern. However, if the OP is seeing the fabric patterns (weave lines) themselves, than the issue will remain regardless of the cut angle.

(the pics are not zoomed in) sorry, why would I put pics here if I do not see any patterns visible to naked eye?. naked eye is even worst than what you see through these pictures

Thanks. So, did you have such a problem, or did you buy ST (acoustic transparent) screen?

So, if you think that the issue will remain regardless, where is the problem? My projector?

You previously said "It is not my projector as paper test was negative". Assuming "negative" means that you did not see the same lines on a piece of paper, then the only remaining explanation is that the screen weave is too coarse for the viewing distance.

Ok, thanks. Well the thing is, what I see, the distance does not matter, even at 16ft, I see the effect clearly- again, this is only visible in the lighter part of the scene/colors. For dark colors or dark scenes, it is just fine, no lines. so, not sure what it is. ST has been kind enough to mail another screen(to Canada). I will post again next week after I receive and test it.

I just called them to ask if their AT material was cut on a angle when I was shopping for screens. I did not buy a ST screen.

The problem is only when projected on the screen so it's when two patterns are on top of each other is when it's happening.

Do you know if your screen is rated for 1080p resolution?

That was why I suggested previously to de-focus the projector to see if the pattern remains visible. That would allow distinguishing projector issue from screen issue and moire interference patterns.

My Moire patterns on ST AT Screen disappeared completely when I upgraded to a 4K projector. (Quasi 4K actually, the Epson 5040)

Obviously, higher resolution will help significantly because the pixles would be smaller.

If you want to test whether the weave angle could help in any way, take the projector and angle it incrementally to see if the Moire pattern improves or even disappears.

Yes I have and they are sending another screen. They mentioned maybe the screen was not cut at a proper angle. I should receive it any day next week, so hopefully will be able to install and test it out by next weekend.

Yeah, maybe I should test it this way as well along with playing with the focus.

Throw a white sheet over the screen and see if you still see lines. If you do...its the projector, if not the its the screen. Some people see weave, some don't.

I have tried white paper test and could not see those line on the paper.

Ok, but try the sheet too so you can see whole big picture from where you sit. If everything looks good I recommend you get a better quality AT screen.

It's Moire. Nothing else. I know this screen well and you have Moire. Defocus or get a 4K projector are your only realistic solutions. Or a better AT screen?

Yes, appears to be moire from his zoomed in pics. Maybe a perforated screen would be best.

To me the lines look like the actual weave pattern rather than moire (you need to view the image at "1:1").
In any case, de-focusing the projector, or changing the zoom, will allow this to be confirmed for certain.

Silver Ticket Screen?

Nope. It's Moire. I have this screen. That's what Moire looks like. You can stare at the screen with projector off and see nothing. Then project a white pattern and then Moire appears. Then zoom in or out and you can watch it 'move'

The posted pictures do show some mild "ripply" Moire pattern, but you can also see the much "tighter" pattern which would be the weave. I'm not sure which one the OP is referring to.

Yes, that would prove it without a doubt.

Thanks all. I think it has to do with projector's projection hitting the weave pattern in some odd way. The lines that I see,shows the weave across the whole screen on ligher scenes. I beleive I need to adjust both, the screen and the projector. I certainly need to do more testing, once the new screen arrives.

I tried to search reviews on amazon with people using the same screen and there is no complaint of moire, so I am assuming either the screen has not been cut at a proper angle or Epson 3000 and ST WAB screen are not a good match. I certainly cannot afford 4K projector @gnolivos . And I am not sure if I can return ST screen, so I have to find a closest solution that I can enjoy watching on my big screen .
