Sounds interesting. I'll have to check them out. The original SmX is what is known as a 2 x 2 weave (95/5). When I saw 4K SmX, the weave itself looked the same, but the holes were much finer. I think we even blogged about the weave not being visible at or just past 3 feet. It was impressive stuff. I can't seem to find the 4K fabric here. The best I have found is a 2 x 1 weave (97/3). The numbers in the brackets represent surface area to hole area, so just 5% for the 2 x 2 and even less at 3% for the 2 x 1. I would love to get some 1 x 1.
That you have no complaints about the image is also interesting. OT a bit, but...the coarseness of weaves could certainly be too great, but most are now quite fine. Even the original SMX is quite good once you are beyond 8' or so. It seems there is a lot of consternation over AT screen images not being as sharp as non-AT. That is true at 2' viewing distance maybe, but I've not seen a good AT yet that didn't resolve just as much when viewed at normal viewing distances of 2.5 or 3 viewing heights. You?
I am still using the original SmX 2 x 2 weave. My current projector is a BenQW6000 calibrated to 6500k @ 14FL. It is due for another calibration soon and what I noticed is that it seems to shift the FL up over time.
I sit at 2x the image height (my front row) and where the screen height is is just 38". Because my screen is probably as small as one would ever make an AT screen, I have to be careful with how bright I can go. The pixel to hole size is close and the projector is a light cannon. The only way to solve this is to decrease the hole size as increasing screen size is not an option in this room and I have the projector wound right down to be at 14FL.
On a full white field, I can see the weave from that distance. The question is, how many times in a film (and this does happen from time to time) does the screen go full white in a movie? It is probably the one thing that bugs me.
The look of the Elite fabric appears to be slightly more visible than the SmX, but in most home cinemas, you won't notice this.
