I have the same interest as the OP’s idea to go from Non-At to AT Scope screen but my projector is a 7yrs. Old Epson Pro-6010 with Panamorph Phoenix Lens as I don’t’ like zooming, for the Lens will allow more lumens on the screen when watching movies particularly the 3D which I enjoy the most.
Before I would upgrade the projector or other equipment to 4K, I think the most important thing I would like to change first is the screen which is going to be my biggest concern for any images going to be projected on it.
I’ve been watching my PVC 117" 2.40:1 scope screen with DIY curved frame for nearly as long as I own the 6010.
The screen is suspended freely with eyelets and high strength rubber bands that keep it perfectly flat with the frame.

Only defect of the screen yields is the sparkle which view at close distance but not with 3D movies as the active glasses likely act like a filter. However my seating is about 13 feet away so there’s no issues here but if I want to add another front row for 4K viewing in the future that screen is going to be a pain to watch.
So this time I eager to choose a new screen with material that can last beyond 4k or like DreamScreen advertises that’s good to 8k+, such that I ordered a sample and try it out.
It took almost a month time to receive that sample from Norway and my order was the mid size A4 about 9”x13”.
It came in an envelope and folded with a big wrinkle right in the middle, at first it felt like heavy fabric not vinyl for sure and colour just like the previous post with image compare it to the sheet of paper.
Right away I put it under my desk lamp and with a Led flashlight shines directly in every angles and very satisfy that I cannot see any sparkle in that close up view. But if I shoot the light from that shiny back black layer, the sparkles will appear on the front layer, that quite convince me the back layer can reflect light to the first layer of fabric.
Next I put the fabric over one of my desktop speakers and use a fixed distant SPL meter to check the db lost and result hardly show any variation from left speaker to right one.
My second thought is that wrinkle that come with it may not be repairable like PVC by stretching, for that mishap can happen again during the installation with a big sheet of fabric which I deeply concern , so I try to press it down firmly and pull it hard on both ends and that wrinkle resist to go away for that fabric is not easy to be stretched at all but that dose not stop me to try using an clothe iron with steam on medium heat, slowly by ironing the black side till that wrinkle is gone completely and with no obvious marking can be found by shinning the light on the lighter colour side.
That’s good news, in case I’ve to fold it and transport to other location, I won’t have to worry the wrinkle at all.
Installing the eyelets to this fabric is a lot easier than the thin Vinyl material ,by which I have to double the edges for a stronger support and this time just cut to the size, pierce small holes and drive the eyelets on and hang it.
For screen test ,I hang the sample with a white thread and flush mount to the current screen and then move it to different spots when I watch the movies . The images that show on the sample do obviously stand out.
A close look the sharpness does increase and colour looks a bit more vivid and for 3D has no impact due the sample size.
I’m quite convincing now that this Screen fabric definitely will be the right choice for converting to AT viewing .
Question is, whom should I order from ?
